Dad and I have a plan, 1/10 nitro converted to bl

[NitroBoy24]

My family and I just got back from visiting our old neighbors in virginia and the guy (we stayed at his and his wifes house) and my dad is now obsessed with his r/c plane that is running a brushless and lipoly batteries :D Obsessed to the point of wanting to get the same plane that he has and put a bl and maybe lipolys in it.

Anyhoo to make a kind of long story shorter he told me we should maybe pick up a brushless motor/esc and try and custom fit it into my GT. And to our luck one of our friends works at a machine shop and could easily help us make a motor mount. And we figured if this all worked out we could mass produce the motor mounts and sell them to the public.


But I am getting a little bit ahead of myself there. I have a few questions:

1. Can the Novak HV-Maxx brushless esc operate off of a Novak SS5800 bl motor? I dont see why not, the only thing in the way would be that it has two battery connectors since the maxx runs off two, but if I were to run lipolys one pack would give it enough juice. (If im not mistaken the hvmaxx esc can handle more volts then the SS esc) The reason I am asking is because if we were to sell the kits itd be more popular if the adapter used the SS5800 instead of the maxx motor since not as many people will own them.

2. I should probablly go to the electric forum but oh well Ill ask any ways. What is a good lipoly battery charger and a company that makes good packs that arent going to kill me price wise?

This is still a distant plan but I think it would be kick ass to have a GT running on lipos and a novak BL :D Then if that all works out like I said we could have our friend make a lot of the mounts and start selling them if people will want them (with out stating it im asking if you would consider converting your nitro s/t to a bl electric lol). And if I want to here the sound of a 2-stroke motor again I could just take off the adapter and put the motor mounts for my ae .15 back in! Heh, once again I am getting ahead of myself.

Are there any major drawbacks are problems (besides having $$ to buy all this) that might stop me from doing this? Also what do you think of the overall idea of this? I know peole are turning 1/8 buggies in to brushless monsters so why not a gt :D

[Craps]

Go to the "Electric Forum" and my thread called "Lithium Poly Batteries", there you will find all the info you need.

And go buy a T-4 or a XXX-T to save yourself alot of grief!

As far as Brushless for the beginner, get the Novak SS5800 and then if you need more, buy a Schulze 18.61K ESC and Lehner 4200 or 5300 motor.

Good Luck!!!!!

[alpinesky1]

No, that esc wont work, you need a Brushless esc. ...

I also say get a T4 or XXXT, its just way too much work to make a gt electric....:cool:

[Strike 4]

Lol Craps I think alpinesky1 lost us both...

I think it would be awesome to have a electric GT, and it probably wouldn't be that much grief to make a motor mount and a battery tray if your friend in the machine shop can do it "easy" . If you make a conversion and sell it for a fair price here is your first customer :). The only problem is the battery mounts. You would need to make post for the clips and a holder so it wont fall out.

As far as Brushless for the beginner, get the Novak SS5800 and then if you need more, buy a Schulze 18.61K ESC and Lehner 4200 or 5300 motor.

Craps, some people can not afford all of the cool stuff that you run, however, I am sure all of us want the freedom of running 12 cells so can he use a HV maxx ESC on 4 Li-Po cells and a SS5800 motor? I would like to know myself, I want to supress 10 cells and have a sensored setup.

[Craps]

The main thing about go with a T-4 or XXX-T over converting a gas truck is that mounting the motor behind the rear wheels helps the weight balance better on the truck rather than mounting the electric motor in front of rear wheels.

If you are on a budget, there are alot of used roller chassis for sale like a T-3 or even a XXX-T that guys have switched to the newer T-4 that would save you alot money and you would be happier with. Also if you're on a budget, go with the Novak SS system for around $225 new or look on E-Bay for between $150 to $200 for almost new system versus the Schulze/Lehner or Hacker systems that run you from $375 to $425 for brand new equipment.

Here is where I buy my Schulze/Lehner systems from:

www.finedesignrc.com

I hope this information helps you!

Good Luck!!!

[gizmoguy303]

Forget converting the GT, they're already electric stadium trucks out there. I say convert a 1/8 nitro buggy into electric - then you'd have something nobody else has! (except for Craps. :D)

Well, whatever you do, it sounds like it'll be a lot of fun. Be sure to post pics when you are finished! :D

[NitroBoy24]

Wow! Thanks for all of the replies!!

After reading all your posts I think I might just end up buying a T4 roller or T3 roller off of ebay. I still think the SS5800 with the hvmaxx esc would be sweet since it can handle more cells..

I have a question though.

Does anyone know if the HV-Maxx ESC can run off just one 4 cell lipoly pack instead of like 2, 2 cell packs since it has two battery connectors? That would be more to my liking because then I would only have to charge one pack of 4 instead of 2, of 2. Can anyone reccomend me a good lipo charger though? I am still clueless on who makes good chargers and packs (besides of like kokam)..

Who knows, I might end up trying to convert my gt, or make it a bit easier on myself and get an electric s/t. A T4 would be my best bet since the T3 has been discontinued and parts might be hard to come across..Thanks for the replies and keep the ideas comin!!

[alpinesky1]

ummm... Ok i read wrong:o , i reread and dont know how i goffed that up, i thought he ment "use the E-Maxx stock esc...." , i must of been high or just read too fast for my brain too see "Novak HV-Maxx brushless esc":o ..........

WoW i need to lay of something
:rolleyes: :D

Im sure the Novak HV-Maxx brushless esc. will work, but its just too big, and you dont really need more then 7cells on the novak, if you want something faster, try a basic 4200 or 5300 and Schulze or lehner, or hacker esc....

Sorry again for the mix up:)

[Craps]

A TP8000-2S4P 7.4 volt pack and the Novak SS5800 BL system is more than enough power to hook up at any dirt off road track. I don't know how you can use anymore. I can't use all the Lehner 4200 has, it is just too much power to hook up.

Good Luck!

[Mr. Constructor]

Maybe this would be a help:

www.coldfusionracing.com/8ths then click on members rides, there are a few converted projects, and there might be some other too, if they will have the time to update their page !!

maybe these ones will help you for the first few steps, as it si not that easy for the conversion, there a re a few well over thought parts, but then everything runs like hell, as the vids show, good luck, and send me a mail when you have any questions, i will try to help you !!

greetings from Germany !!

[NitroBoy24]

Thanks for the links Mr. Constructor :) And when/if I do a GT to BL project I will email you..And Craps, and dual bl, or anyone else thats done a nitro to bl conversion lol.

Whoa I just thought of something that is REALLY important for me to know!

How many cells are in the TP6000 pack??? Also does anyone know how many volts the novak ss esc can handle? Crap I know losiguy1090 knows..I think it was like 14.4 volts or something which works out to be 2 lipo cells.

Thanks for the help :)

[Craps]

The TP6000-2S4P 7.4 volt pack is a 2 cell pack. That is what the 2S stands for in the number. You will not find these on TP's web site, but you can call them to order it ($119).

Good Luck!

[Mr. Constructor]

You mean the HV version?? it has 12 cells (14 as the EVX does is OK too, but not a gramm higher !!;-) )

and the SS has only a 7 cell limit, wich is the major feature that it does NOT run in a 8th conversion, as the power is greatly limited too, the esc is rated at 225 W (for a good 8th conversion you propably need 600 W (peak of 1000 W is OK) then you´re good powered (12 cell is recommended, everything below puts the power to weight ratio down, and anything above either as the car runs too heavy (with 12 cells, a good weight is around 3,5 kg total ready very good is everything below 3,1 kg !!)

The conversion of any gas car isn´t that big thing, as the BL motors are quiete very similar in their behaving than nitros are, except that the torque is better in every rpm range and they do react more linear (the nitros only have a small power band)

[NitroBoy24]

Whoops,
Mixed up the voltage numbers on the ss and hvmaxx yesterday in that post :o The HV-Maxx controller would be nice for the extra voltages but a 4 cell lipoly pack or 10-12 nice nimh cells is way to much for now..Eventually the price will drop and I will have a job so I could upgrade to a schulze controller and some lehner/hacker motors :D

I got grounded from the internet for a week yesterday night, so my only refuge is having access to a school computer for about an hour after school, but I have a lot of homework that I want to get done and out of the way!

For now the novak ss and say a tp6000 pack should be "adequate" in my gt ;) :D

[glassdoctor]

Where can I get a TP6000 packs for $119? Are these the newer "high-c" discharge cells?

Thanks.

[Mr. Constructor]

as for the Li Pos, try this one:

www.thunderpower-batteries.com

the pack you might be looking fore is the 5700 mAh 7.4 or the 11.1 V pack, the 7.4 is around 120 USD.

@ NitroBoy24:

Yes the Novak SS 5800 (there are 2 versions out there) might be good for beginner, but be warned, this system is "only" able to produce power like a good 12T Motor, so maybe this is too low for you, rethink it with a Lehner Basic 5xxx series and a LMT Warrior (the low speed driveability is worse comp. to the Novak, but the rest Datas are way better !!
(and then check out :
www.kontronik.com for really a great esc (with switched BEC up to 18 cells and programms for ALL types of RC for around 160USD and the Motor (take a lok at the twist series (same than fun 480 but suited to cars !!)

maybe the Novak SS 5800 gets in the shadow at these parts ??

[Craps]

Just had a long talk with Jason with Thunder Power on the phone yesterday and all the batteries sent out from now on will be the new type with the higher "C" discharge rate.

When ordering from TP, planning on waiting a week or 2 due to the large amounts of orders they have recieved and they are not even advertising on the RC car side yet or do they really need too with me out here.

I wish I could have bought stock in the company!

[NitroBoy24]

Thanks for the help mr constructor ;)

I have a question. Which esc for $160 were you talking about? There is the smile and jazz series here:

http://www.kontronikusa.com/escs.html

Also,
How much would a lehner basic 5xxx motor and LMT Warrior cost me? And where can I buy one online? All of the links on www.finedesignrc.com wont work so I cant find prices until I find another good site that sells them..

Do you know how good lehner or kontronics customer service is? I dont want to buy a brushless, have it die, and wait forever to get a replacement :)

Also on the "Twist" motors, are they a 480 size like the fun series or are they 540 sized which is what all 1/10 rc's use? Also, I could find any twist motors for sale and the the rpm per volt on the fun 480 motors were very weak (2800 and 3300 rpms).

Thanks for all your help guys!

[alpinesky1]

The Basic 5300 is $150 ($140's something), as for a controller The 18.61k is what you should get if you go the sensorless route....

After talking to Chris F. at finedesignrc.com , he said the Sch 18.61k and 5300 should be 8mph faster on 6cells/or a 7.4v lipo, then my aveox rc7 on 6cells/7.4v lipo.....

BTW (my aveox rc7 is a hair faster then the novak system, but has way more torque)
Also i love my aveox system, on 7cells it will run with the gas boys, but i only will be running 6cells/7.4v lipo packs, so im selling my aveox for a Sch or Hacker or Lehner setup:) .....

aslo you can email Chris F. at ( chris@finedesignrc.com ) he should help with priceing since there webpages are down..;)

[alpinesky1]

Quick question............................

90% of the time where/or what will you be doing, with you BL Truck?

Playing/Bashing, Raceing on Dirt, Raceing on Pavement, etc.... this will help deside what motor/ controller you need......
:cool:

Just like a real car if you try n put a 6,000hp motor in a baja/statium truck, youll well, be sorry :( , on the other hand if you get a 6,000hp motor and a cheap controllerand race it on a F1 track it will thermal all day long, and vise versa...:)

[NitroBoy24]

Sorry for not answering for a few days, grounded from the net at home and the forums were down yesterday, yatta yatta yatta.

I will be bashing like 90-95% of the time if and when the GT is converted to BL. I will doing a lot of pavement bashing (in my neighborhood), in dirt a lot of the time, grass a lot of the time (if its electric and quiet which it will be Ill be bashing on the golf course!), and some sand :cool:

With that info in mind can someone recommend me a controller and motor? I will be using either a TP6000 or maybe a TP8000 pack if that would sway the decision any..

Also,
Since the finedesignrc.cim site is down does anyone know off hand how many rpms per volt the basic 5300 (or the motor you'd recommend) puts out so I can calculate how many rpms my truck would be pumping out.

Thanks again,
NitroBoy24 (still gettin used to the new layout

EDIT
Finedesings site is back up!!

[NitroBoy24]

Looks like the Schulze 18.61K esc will be more then enough for me right now! $225, I can easily make that much money just from allowance and selling some old N64 stuff on ebay. Then $140 or whatever for the lehner basic 5300 (which I can find on finedesignrc, anyone have a direct link? Maybe Im blind!) and $120 for a TP6000, $110+ for the astroflight 109..Kinda pricey :), oh well I have money burning a hole in my pocket anyways.

One other thing,
Is the SS5800 motor the same diameter/width/length as the basic 5300? Does lehner have a home site where I can find all this information? I just want to know so if our friend can make a couple bl conversion kits I know what motors will work with it..

-NitroBoy24

[OptimaMan]

The SS5800 is essentially a 540 "bolt on". It's about 1.5 inches in diameter by 2.0 inches in length (not including shaft). The Basic motor is also about 1.5 inches in diameter but it's only 1.5 inches in length (not including shaft and wires sticking out).

Now, here's the kicker... when I open up the Novak motor, the rotor is longer but smaller in diameter than the Basic motor. SO, the Basic motors will always have more torque than the Novak ss5800 motor and be less prone to bogging down due to gearing too tall... meaning if you gear your buggy 20:1 (hardly any load to the motors), the Novak will probably be faster than a Basic 4200. However, if you gear it like 8:1, the Basic will probably be faster.

Be careful with the 18.61K and the 5300. The 5300 COULD overheat my 12.97 (w/o heatsink) at times during indoor carpet TC racing so it possibly COULD overheat the 18.61K also. Fortunately, the heat sensing in the controller works well and will shut down before it burns up.

[Mr. Constructor]

@ NitroBoy24:

the Jazz series of esc´s from Kontronik is the one that´s around 160? here in Germany, maybe your shop will sell it a little higher, but take a look on the flyer shops, as the esc´s are very popular within the flyer scene !!
And for the Motors, the twist´s are available as a 5600 Rpm/V version, this one might not be shown on the american pages, try to surf to the german ones, there you´ll find all datas on it.
As for the size, the Twist is slightly bigger than the fun 480, due to the heat finnes around the housing, the rest datas are similar to a normal 540er type !!

(the weight is lower, the torque better and rpm/V better than any 9T Motor, so try it out, most shops do carry the kontronik brand, maybe they´ll have to order them for you !!)

As mentioned by the others here:
the Basic series from LMT DO draw much more AMP , so you might try the Kontronik ones, they´re better suited for cars, the amp draw is reduced and the driving time exceeded due to better heat flow and lower amp draw !!
I think i saw them at www.stormerhobbies.com, they do carry some LMT, and some Kontronik as i remember.

As for the bashing around, everything around 5000 RPM/V might be very good, the speed/power is above a 9T and running time should easily reach the 8min mark (with good cells off course, but if you plan on using the TP Packs, you´re always on the safe side !!

see ya !!

(have i said, that you get a 10-15% off on the selection of a jazz esc combined with any twister motor ?? (ask the dealer for that, is a general thing here in germany (from Kontronik ITSELF !!))

[glassdoctor]

MrConstructor
Does the Jazz controller have brakes? Suitable software for cars? I thought it was just another airplane esc.

NitroBoy
The Basic 5300 is 5300k/v. Makes sense, huh? :rolleyes:

Maybe I'm a little off here, but I was just thinking that a great setup would be a Basic 4200 and a 3 cell Lipo (11.1volt). Go to 4 cells lipo for even greater speeds.

That should be awesome in a 1/10 scale, with the extra voltage. Major torque and speed.. and the amps should not spike as high with the higher volt battery, in theory anyway.

Watts=ampsxvolts

Any thoughts on that?

[NitroBoy24]

Thanks for more replies guys :)

glassdoctor,
A 3 or 4 cell lipoly would be ideal on a basic 4200 but a lipo with that many cells would be insanely high price wise. Also, the jazz esc is suitable for cars :cool:
http://www.kontronikusa.com/konm3100.html (there is the info on it)

Mr. Constructor:
Have you or do you know anyone that runs the Jazz esc?? The thing looks and sounds like an awesome deal to me! Around $160 (from what you have told me), 6-18 cells, compatible with cars, planes, boats, etc! If I wanted to could I run a basic 5300 on that esc? The only information I have found on the esc is on kontroniks site so I am hoping you know more about then I. I think the 5300 would work since the jazz esc is most likely sensorless. That twister motor sounds nice also and a 10-15% discount would be easier on my wallet!

Like I have said a million times...Thanks!

-NitroBoy24

[NitroBoy24]

Wow..Good news!! The Jazz ESC is compatible with sensored AND sensorless motors! So for some reason I am short on cash and HAD to buy a novak ss5800 I wouldnt be SOL with the jazz esc..

I want to know if you guys think a Jazz esc with a Basic 5300 (or the twist motor that I think only mr constructor would know anything about lol) on a 2-cell TP6000 would be a good setup? Me thinks it would be! Then maybe a 2 cell TP8000...Insane run time!

[Mr. Constructor]

@ glassdoctor:

as for the esc: it has programmes built in for all application !! (heli, boats, cars, funflyer a.s.so.) and the car programm can be switched between brakes only (wich are proportional) and brakes and then reverse !!

as far as i know, due to many tests and speeches to others here at the pages, the basic line DOES draw a lot of amp, as the rotor is fairly small seen to the competitors productions (they´re mostly longer but little thinner) the motor does produce a good strong magnetic field, but that wants some amps in any case, so try to use a motor that is better suited to the car, the fun 480 (and the twist) are better suited for this application, due to their smaller torque (bet me, it´s anyway much more than any brushed 540 design !!) but this is more than enough for the smaller 10th cars, i do drive 2 of them with a Hacker B 40 S Series motor, they are powered that much, nothing above is needed (see the pic)

@ NitroBoy24:

the basic 5300 could be used for the jazz and then CHECK the motors voltage end, the lipos maybe too high, also the rpm at the end should not exceed the 60.000 line (as a 100.000 line is said, but to be on the safer side, thge rotor will not crack in these conditions)
I was thinking of a 6 cell powered car when i told ya the basic 5300, so if you really plan on using lipos (they DO HAVE TO put out around 50A peak for maybe 10-15sec. check that out !! or the batteries might be damaged)
so with these extra volts, you might be right with a 4200 motor !!
(the 6 cell rpm at all under load with the 5300: around 38.000 (at around7 v during hard accleration) same with the lipos, they should have then (with a 4200 Motor around 44.000 (calc. with 3.5 v under load, but they might be getting down more, as the motor will hit easily the 40A Or even the 50A mark)

try to get a setup with around 40.000 rpm at all, then you´ll be on the safe side, this will be OK for the car, and the speeds are great too (not really flying, but close to that without damaging the esc or the motor or even the battery packs (due to overload !!)
As for the sensorless motors: ALL sensorless esc´s will handle these motors, as the sensor wires are not needed and will be hanging at the motor unused, the electronics (in the esc) will replace them, so these JAzz esc´s will work with almost every motor (even LRK´s will work!!)

The basic 5300 will devinetively be too much for the lipos, as they draw too much amp, then you might go with the 3 cell lipo and the 4200 (or similar with the twist,this motor will draw less amp, and producing enough power to get your car running very high speeds !!)

And check this out first too, there will be a new charger also, that is aMUST HAVE when using lipos, so take this in account too, this will cost you around 100-150 USD (when having a good schulze one) maybe the good old Nimh cells are better for now, the lipos are way too costly for now!! (i am NOT using them so far (only as transmitter batterys or receiver packs on my big scale electric ones (safety reason!!)) as the batterys size is not comparable to any other sub c 6 cell packs, so these packs will fit only in this specific car (i have too much of them to built all around to the lipo size !!)

see ya !!

(and for getting more info´s on these Products (or even getting them to you, i will try to help you out !! (i made several postage handlings for people like you, getting them here in germany and then having them send to the us, or wherever they live !!)

greetings from germany

[glassdoctor]

mr.constructor
How do think the hacker c40 series compares to the twist and basics? I wasn't sure what you meant... Also, I thought that a thinner, longer rotor would be more of a high rpm, lower torque and amp draw?, in general... That's how I've heard the Basic compared to the Novak... the Novak is weaker with a smaller rotor, with less amps.

As for the Lipos, it seems that they are in fact good for BL setups, even with high amp motors. Some of the guys are using lipos in Emaxxes and 1/8 buggies... I was concerned about lipo/amp draw too, but now i keep hearing impressive stories about them. And they appear to be able to deliver maximum voltage under load, so that they have more "punch" than comparable Nimhs. Everyone says a 7.4 lipo is noticabley faster than a 7.2 3300 pack, the best nimhs. But the catch is they can literally kill themselves in the process! :eek:

I'm going Lipo pretty soon...

They are expensive, but if you look at the cost per amp hour, they are not much different than what good quality matched NIcds and Nimhs have alwasy been. Before the GP cells hit the market, an average matched 6 cell pack would cost @$60 with the best ones @$70-80. That's for a 2000-3000 mah pack. Now you can get good GP3300s for $40-60 ea.

But a 7.4 2000mah lipo is about the same cost really.

For my Emaxx, example:

lipo: 14.8 volt 8000mah pack @ $300
lipo: 14.8 volt 6000mah pack @ $240
nimh: 14.4 v 6600mah pack @ $200-240 (4 packs @ $50-60 each)

The difference is that you can go with budget nimhs for @$120-160, but for some real good nimh the cost is similar, and the Lpos arfe supposed to actually perform better.

Interesting...........

[NitroBoy24]

Mr Constructor,
I already know I need a lipoly charger (astrolfight 109, like $110).

How do you think the twist motor would do on a 2 cell lipoly battery (equivalent to a 6 cell nimh pack)? I havent been able to find info on the twist motors, so I was wondering if you know how many rpms/volt that motor will make? I am aiming for around 40k rpm's like you mentioned, but I need to know how many rpms the twist is capable of!

So,
I take it the basic 5300 on lipolys is not a good idea? I could get a TP5700, 3 cell pack for $172 which isnt too bad and then run it on a basic 4200 which would give me around 46000 rpms.

I need help with an engine choice though. Can someone recommend me a motor that would work good with 2, lipoly cells instead of 3?? Or would the basic 5300 work? I'm still a little bit lost on why it wouldnt be a good choice for a 2 cell lipoly which is the equivalent of a 6-cell nimh pack..Thanks for educating me on lipos and bls!

[glassdoctor]

I'm not the most experienced in bl, and I've never run a Basic5300, but I have heard good things about 5300 on 6 cells in the past. I thought it was one of the best choices... isn't the only negative that it's a little bit of an amp hog compared to some other motors?

Also, the new 10C lipos should be great to use with it as I understand. The 5700mah pack you mentioned is good for 57 amps continuous... more than enough for a 5300 in a 1/10 vehicle. Some are running bigger BL on these lipos w/out any issues.

I have a Hacker C50 now, so I am thinking of trying a hacker C40 for one of my 1/10s...

mr.constructor, is that a hacker in the picture?

[Mr. Constructor]

@ Glassdoctor:

In general you´re right with lipo´s, they do cost the same if you wanna higher quality cells !! but the use of 2 cells (as a comparable 7.4V pack) isn´t that good choice, as the power the emaxx and the 8th conversions uses would be generated by much more voltage (maybe 3 or 4 cellsin series and then 2 parallel) but this will rise the costs on the pack that much, that it might be easier to run 2 packs of the old good NiMH cells.

OK; I will try out (faster or slowlier in time) the lipos too, but as for now a really new KONION cell aproaches at the market wich could handle around 12-15 C and a peak (for 30s) around of 20 C !!
These cells where produced by kontronik too, (the name said it already) they´re not Lipos !! (the liion cells are way better in the high amp conditions (i used mine in smaller12th cars, they run OK (although they´re only borrowed from a Laptops battery wich can handle only 6-8A)

These cells will be really making it easy as they provide a closed HARD body (similar to the Sub c bodys) they could be soldered easily (same than my Notebook ones wich are now in my Computer Radios) and will not been destroied as a safetey circuit (against: overheat, overload, underload) is built in.

The only "bad" thing is that they come only in 1100MaH sizes for now (planned up to 2000 MaH ) so the time is there, these cells have been tested in our german flight magazine, as a discharge rate of 18.2 A (they really did handle it, getting around 700 Mah out of them !! (on a 7.4 and a 11.6V selection)

Pretty good, but not in the same size than the sub c´s (wich would be really great as most of our cars accept them without any building (if you have as many Cars than i have this thing comes in common !!)
Here is the german HP description on the Twist series (the german writings have been translated, it´s a general overwiev, see pic for the motors design, i´m searching for tech datas (diameter a.s.o.) as soon as ai find them i will post em !!)
Twist 28
* 2800U/min/V (voltage rating)
* 6-16 Zellen (cell count in wich the Motor could be used)
* 5-30A Dauerstrom (continous amp draw (depends on gearing, cooling a.s.o.))
* 50A kurzzeitig (Meaning short time A draw (during accleration for excample))

I forgot to say yes it is ahcker B 40 S series in that GP truck (the electric was 50Euro more so i choose the GP, removed the Motor and used the Chassis (better more stable drivetrain anyway) as a ideal basement for BL use, the vid of this car could be send to your e mail, maybe around 4MB (maybe thinner, depends on quality and what you like (the compression had to be done aynway)

The C 40 is way too heavy for a 10th, the power of these B 40´s is way enough for these small cars !! (and they´re cheaper too)

@ NitroBoy24:

as you thought a lipo out of 2 cells would be too much amp draw on a 5300er esp. if not geared totally right !! (wich does happen more often than you might think, many people cooked their motor and esc due to this peoblem, when you detect it, it´s too late !!)

the only way for 2 cell lipo is the lighter car (on road not offroad) and then a good setup that really goes hand by hand with the rest of the car (during accleration the lipos will hardly go down on their voltage (mine where running 4.2 at 2A then 2.7 at only 8 A, so they do go down the same than nimh´s do, take this in account, to use a 2 cell lipo in that car, maybe the tp 8000 pack would be OK, but its bigger in size than the 6 cell sub c, so you might get space problems !!

Hopefully the figures from the Twist´s will show you what i mean, these motor are better suited for cars and they´re not that heavy (in power and weight) than the C40 are (they´re better for 8th or MT´s like the Emaxx)

as for the Tech Datas i connot find them at the german page, but ive spoken to the designer itself, the size is generally the 540 !! (with the mounting holes of a 400 a 540 and a 600 series !!)

greetings from germany !!

(another pic with gear at this time (the motor is used in the flight scene too))

[glassdoctor]

yeah, 2 cell lipo would not be any good for a maxx... but the 4 cell 14.8 would be great. "Craps" on this forum is getting good results with a 14.8 8000mah pack (2x 7.4V packs) in a 1/8 buggy with a Hacker B50 9XL motor! That's a big motor :eek: I want to try that!

Thanks for the Twist info... I did find them on a site, but there wasn't a lot of info, pics etc...

The 5500 sounds good for a 1/10, right? Are they similar in size, power to the Hacker C40 series? Can't really tell by just the specs... it would be about 600 watts @ about 12 volts?...

[glassdoctor]

Mr. constructor, could you try to email me again using a different address?

clearconcepts@mchsi.com

That should work, and I have broadband so no trouble with the large files. Thanks!

[NitroBoy24]

Mr. Constructor,
Is the number next to like volt (in the motor info you pasted) is the 4700 or whatever rpms per volt or just like an amp draw thingy?

Also,
Can you recommend me a twist motor (size wise) that would be running on 2 5700 or 6000 lipoly packs? It would be going in my gt, and Im looking for like 40,000 rpms or more :D. Thanks for all your help!

[glassdoctor]

Yes the Twist 47 is 4700.... actually 4750k/v or rpm per volt. (correct me if I'm wrong Mr.C)

The Twist 55 would produce 40700 RPM on a 7.4V Lipo :D

[NitroBoy24]

Yes the Twist 47 is 4700.... actually 4750k/v or rpm per volt. (correct me if I'm wrong Mr.C)

The Twist 55 would produce 40700 RPM on a 7.4V Lipo :D

:D

And I could get a 3-cell lipoly pack and if I am right that would be 11.1 volts...Times 5500...Which equals...61,050 RPMS :eek: :D or to be on the "safe side" I could get the Twist 47 and get 52,170 rpms :cool:

I think the 5300 is definitley a keeper..And if I want some crazy, fast speed I could get a 3-cell (5700 mAh) lipo pack for $170 or so and be spinning some seriously crazy rpm numbers. I would have to watch my throttle finger incase of cracking the rotor though it should be able to hold up to that many rpms.

This has been a good day!

[Mr. Constructor]

If you plan on using the Lipos in 3 cell mode, go down a little with the RPM, the twist 47 might be better, but you could not switch back, so think over it enough, the motor might not be that cheap, the 5500 Rpm Motor might be better suited for the 6 cell sub c packs, but it will handle the lipo 3 cell too, the Amp draw will take the voltage down, so there might be around 10V dring load, this is aceptable, check this out: the max. RPM should not exceed the 60.000 RPM line, equally wich cell count or RPM/V readings or even under or without load it should not be exceeded !!

I will try the Twist 55 in my Dyna Storm (it is the re-released version) to see weather it will perform with 6 cell sub c or not, but this takes a few months, the car will be mine in may (a birthday gift from my wife)

The combo 3 cell lipo and the Twist 55 shouldbe OK !!
(under load the RPM will not crawl over the 60.000 !!)

[NitroBoy24]

I plan on just running a 2-cell lipoly motor for now, so if I want some more speed Ill get a 3-cell!

Do you know how much the Twist 55 will cost? (us currency) I am going to go see if I can find it on a site that sells plane stuff (like you said) but if I have no luck Im pretty sure you will know :).

[Mr. Constructor]

In this case the Twist 55 is OK !!
The Twist sells around 150Euro here in germany(JAZZ 40-6-18 is 150 too, JAZZ 55-6-18 is around 170 others have to be asked), so i think in US it might be little more du to the Shipping costs, maybe you shouldlook at the flyer´s side at this forum to get prices in the US (back to the main page and then select the plane sector, there should be more info than you might need, if nothing really worked, I will help you out and order it for you here in germany (i need a similar one for my Car too, a friend will be having a 3rd one, so the shipping costs are near to nothing, only the international (from Hamburg to you have to be payed) and i could get you a JAZZ esc too, the time of delivery is around 3 days here to me, then from me to you, should take around 2-10 days (what you like)

It isn´t a great problem at all !!
(Send me a Mail if you wanna discuss the safety things with me, IF you cannot find any parts in the US)

http://www.icare-rc.com/kontronik.htm

They have the Twists an sale for $132

Jazz 55 $213
Smile 50 $145

Wouldn't a Smile 50 be plenty for a Twist? That would make a really nice affordable combo.... @$275 on sale :)

MrConstructor, you're too kind... is that a standing offer to help get us stuff? :D Hopefully we can find good sources here and won't have to bother you...

[Mr. Constructor]

Be careful, a smile hasn´t got the lipo mode and the 50 Aversion is ONLY a optcoupler version, the smile range with BEC goes only top at 40A (50 A peak) this might be too low for a good Car, go with the JAZZ, the software is the latest you could get and the PC interface is in there too (you´ll need a spec. adaptor cable for it !!) and the software oprions are more too in the JAZZ.
The SMILE is a good esc, but onlay for 10th pan cars or light 12th carpet racer, the amp draw of a good Sedan or offroad might be moore than 40 A during accleration, so stay on the safe side, this JAzz will be a better choice (esp. if you plan on using it in several Modells (such as boats planes, Cars, helis, the software is built in !!)

see this shop at:
www.icare-rc.com/motor-controls.htm it´s in Canada, maybe it´s a solution ??

Otherway: As for my offer , YES it is a standing offer, if you could not find whatýou´re searching for, i will try to get it to you from Hamurg !!
