Assuming the fact that the hv4400 moter has the same rpm limit as the ss4300 and ss5800 motors, you may be able run ss4300 on 10-14 cells for 700 watts of theoretical power output. (175x4). Using the hv maxx controller of course. The power rating for the esc is iffy though.

Whoa, the HV Maxx gets released? Wonders will never cease...

I'm not convinced performance will be that great though. For starters it is a sensored system which already limits performance dramatically...and Novak don't barely mention higher performance in the HV Maxx ads, they focus on the zero maintenence area. If performace was so awesome they would be shouting it from the rooftops. But we will see, I suppose.

I could care less about the HV motor. The HV- ESC coupled with a 5800 or 4300 would be neat :D. High voltage! :eek:

SpEEdyBL

It's not the sensored part that limits the performance. 70,000 rpm is more than most sensorless systems spin anyway. You haven't tried using the hv maxx yet, so how can you make assumptions? Forget about how the super sport performs, its a different motor.

They said it goes 32-38 mph which is simalar to the speeds reached by many sensorless systems so it can't be that bad.

If I had to guess, it'll not have the power of the C50 maxx motor or the Basic XL but more in line with a C40L series or 1530 motor. So, yes, it might be able to suck up 600 watts for extended periods of time, but the diameter of the rotor is small so less torquey and less amp hungry. If you ever open up a Novak motor, the windings are thick and the rotor is a short diameter - similar to a 400 size motor. I took apart the 5800 and a basic motor for comparison a while back ago - it's somewhere in these threads. Now, this is assuming that the HV motor is a longer version of the SS5800. However, if the motor is a larger diameter can, these assumptions are totally off!

Even the speeds (32-38) are appropriate for what I'm guessing (remember, the C50 maxx motor and 3100XL will take it to about 43 mph on good 14.4 volts)

Just because a motor is sensored doesn't mean it has less performance.

My 2cents worth.

If you think about it, sensored systems are in their baby years still, at least for Novak. I mean, if you look at all the systems out on the market for cars, the only other sensored system is/was the Aveox RC7, albeit a 4 pole, but it was ungodly powerful. That system is no longer really sold as the sensorless technology has advanced. It's kinda like when Ford first put out their 4.6L V8. It was new technology and wasn't very powerful. Now look at the '05 GT's 4.6L powerplant. It pumps out 300 horsies now, and with a few intake, exhaust, timing, and other simple mods, it can put 300+ horses to the rear wheels N/A, coupled with removing the rear seats and some dead weight, it'll supposedly run a 12.3!:D Basically what I'm trying to say is Sensored technology is new for Novak. Give them time to refine their technology and it'll be just as, if not more powerful than sensorless, and still maintain silky smooth throttle control...:D And don't judge a book by its cover, ya never know what's inside;).

I am gladd to see that novak went to a larger diameter shaft for the part that is in the motor and the bearings. It appears that it is cut down to 1/8" only for the pinion gear section of the output shaft. This may make them run smoother than the 5800 series. Novak managed to make the loudest brushless motor I have ever heard when they make the ss5800. My personal opinion is that it is due to using an 1/8" shaft all the way through the motor. Plettenberg does this too... but they don't have the 1/4" gap on eithe end of the motor between the magnets and the bearings. I believe it is this gap combined with the weakness of the 1/8" shaft that allows the motor to vibrate slightly when each coil pulls on the rotor. Have to see what the new motor is like.

SpEEdyBL

12-12-2004, 07:07 PM

Or maybe it's the bearings. They're smaller and not as smooth.

Don't tease us man, who is shipping this now?

Tower lists it for $279 slotted for late Dec. shipping.

Novak specs. 375watts of power, will this be enough to push an 1/8th buggy conversion, how much does a stock E-Maxx weigh anyone know?

On a possibly related note, some pigs flew by my house today! and I heard rumors about snowball fights in Hades :D

glassdoctor

12-13-2004, 10:24 PM

A light emaxx, mostly stock with about 12 cells and one BL motor setup, and a few things stripped for weight should weigh @ 9 lbs. I have the numbers on mine somewhere... it was somewhere close to that. Some of the heavily moded aluminum trucks push 12+ lbs.

A buggy will be lighter than a race ready emaxx, and the drivetrain mass is a lot less.

I think the Novak HV motor might be too "hot"... but it's an interesting possibility for sure. Too bad they didn't still with something in the 2500-3000kv range.

The motor wind just doesn't seem right for the application. It's only rated for 375W yet it's a very high rpm motor for it's size and purpose.

Add to this the 32-38mph claims form Novak, and it's obvious that either the kv # is just bogus, or it has so little torque that it only makes about 2/3 of the rpms it should in the truck.

At least when you compare it to what other motors do with the same setup... same # of cells, same truck... same speeds or less than lower kv motors.

I hope it doesn't just run hot and have thermal problems cause it's the wrong motor choice....

glassdoctor

12-13-2004, 10:28 PM

I'm assuming this will need to be geared very low to work right in a emaxx, which is fine if it works well.

But in a 1/8 buggy we can't just gear down another 20% or so .. without some modifications for a bigger spur like the Ofna Dom. I don't want to do that...

jocktheglide165

12-14-2004, 02:18 PM

just teasing man I dont know whats going on I still like Novak even after its been year and half in the making of HV. I highly doubt anyone here will make fun of the HV once its out the only folks who will make fun it will be promod, glassdoctor, hiamp, etc.. the folks who push the brushless to the extreme of 70mph plus. U guys probably demand the HV push 50mph if we didnt know any better. Nothing wrong with that, but theres always the 400 to 600 controllers for ya out there for you guys to test for us poor folks..

kufman

12-14-2004, 06:38 PM

It will be interesting to see how the HV has to be geared in a Maxx. I run a Feigao 10L (2480 RPM/V) with 70/16 gearing (stock tires and diffs). This setup get my U-force 75 pretty hot (160 -170), but runs really well. If the HV system can only handle about 25 - 30A continuous, that motor will have to be geared 72/12!!! I was really expecting Novak to make something closer to 2500 RPM/V. I did figure out something the other day though. Novak quotes a no load rpm number and everyone else seems to quote a loaded rpm. Anybody have any input to this??

ElectricThunder

12-14-2004, 07:16 PM

They do that possibly to make the average consumer think it's better than the competition. When they look at the lehner 5300 and the SS5800, they'll think "oo! Higher number! GIMME!" That's my take on it. On another note, anyone know how much an HV controller will go for? I'm thinking that instead of getting a whole new system, get the HV controller and use it with anywhere from 6-12 cells on the novak 5800. (that is if the controller isn't the cost of an SS5800 system or starluck combo).:D

glassdoctor

12-14-2004, 11:49 PM

Well, I talked to Novak today... but gotta call back tomorrow to get the right guy who has done the testing of the system. Anyway, it sounds like they will only be selling the combos at first. They did the same with the SS... it was a little while before you could buy them separately.

I'm going to try to find out more about the motor. Like, does it simply need to be geared lower due to the high-rpm traits. We'll see. The guy I talked to just said they were getting basicly low 30's typically, but he wasn't really the right guy to ask.

Jocktheglide... actually I wish I was one of the guys with extreme BL setups... I am working on it. :) I have a Hacker controller/ C50 in my emaxx, and I run 12 cells matched 3300s. That's about it for me, other than a Novak BL. I do have a couple other motors, and a 1/8 buggy in the works because the emaxx just isn't tough enough. I've been too busy, and more in the "planning" stages for the past year.

This stuff is expensive... I have to buy junk when I'm feeling irresponsible, he he.

I want something that I don't have to play nice with, so the emaxx has got to go... ;)

I'm also going to ask about using an Aveox motor with Novak's HV... maybe that would make a nice combo for a buggy or maxx.

SpEEdyBL

12-18-2004, 01:59 PM

They changed the cell limit on the HV esc. You can now run down to 6 cells on it. So people with those SS5800s might be able to safely run 8-10 cells.

ElectricThunder

12-18-2004, 02:50 PM

The highest I've heard a 5800 motor could take is 12 cells (supposed it makes sense since it's actual loaded Kv isn't 5800). 13 made it smoke :eek: . Looks like a new little door just opened up for those with the 5800 and want more power:D.

I back ordered mine nov. 12, 2004. I hope you have your's before me.

came with the fan for the heat sinks and a heat sink on the motor both are very welcome to see come in the box included. now could you find a larger capacitor? :cool: that thing is large compared to what I normaly see. another nice touch is the cover to help keep dirt out of the open motor hole in the mount.

on an e-maxx there is only one slight problem that has happened and it is an easy fix, the stock battery strap (when using stick packs) hits the motor heat sink and you are unable to get it in place, have no fear the heat sink rotates and the stock battery strap fits between the fins. I was thinking I was gonna need to da a "little" dremeling too, lol... oh well.

now if it could so nicely stop raining I could go for some test runs and see how many parts I can break and make a price list for stronger parts. :)

Nice setup fuzzy! Looks like you can pop rolling wheelies easy with this system. From what I've gathered, all it takes to really wake up the novak is just more cells.. Hmmm. I definitely think they need to couple the 5800 and 4300 motor with the HV maxx controller..:D

glassdoctor

01-01-2005, 11:59 PM

Nice report on the HV. Was most of the video run in second gear?

I run similar setup with my C50 20/66 and 12 cells, but I have it locked in first gear. So I'm wondering what the HV is like in first... acceleration and top end.

I'm beginning to think the HV would make a decent 1/8 buggy setup... just have ot ignore Novak's 4400 #.

fuzzy2133

01-02-2005, 02:56 AM

I was switching between 1st and 2nd. the wheelies were in 1st and the tires would just spin when I was taking off in 2nd may have been since the ground was still slightly damp. I am going to play with the gearing some (20 or 21/70? or 19/64?) the ESC was stayed cold thanks to the fan. I have a couple 7 cell packs ordered and on their way it should be interesting. also thinking about running a RX pack since the truck is still fairly fast in 1st gear when the batteris dump and this causes a power loss to the stering servo.

ElectricThunder - in time I think Novak will sell the HV ESC alone many people want to run the 5800 and 4300 on a higher cell count.

will there be a significant improvement in using a hv speed controll with a 5800 motor with only 6 cells? not much extra room in a b4...

glassdoctor

01-06-2005, 03:17 AM

The HV is a huge heavy controller for a buggy. It weighs almost 3x as much as the SS controller. It would work but I wouldn't bother unless you want to run 10+ cells. I bet the old 5800 would really wake up with 10-12 cells. :)

If someone has a Novak 4300... maybe the HV and 14.8 lipos? :eek:

If you want a better controller for the 5800 motor and 6 cells, I would get the new reedy controller. It's smaller and lighter and supposed to be able to handle more than the novak.

I just instaled my HV in my E- Maxx..Wow,Who ever said 38mph is way off,It's much faster than that,Just smokes my buddys Revo and LST,I would put the top speed in the 40's(45+)I was getting around 12 to 18 min. run time(that was around a track)I know this is big difference but sometimes I drive like a spaz :p On the 1st gear speed thing..Its hard to explain..but it would want to flip on it's back(roof)every time I would nail it,so I just stuck it in 2nd gear.This was on the street,In the dirt it was almost as bad,it was almost impossible to get around the track in first without getting it real sideways or spinning out,it was much easier to get around a track in second gear.I tried bow tie 40's,Panther Dragons,hot bodies mini pins.It makes the E-Maxx alot of fun.. :D

2 7 cell 3300 matched packs @ 1.17,On the speed I had no radar gun so at best it's a guess,but it was alot faster than the Nitro's I was running with.When the track was in "race trim"(had traction) it was so much quicker out of the corners than the nitros..Wow,clearing the triples was not a problem.. :D

Novak recommends 1 tooth lower than stock(70/14)I was running 70/16 and the speed controller did not seem like it was to hot(I am using the fan)I should check it with my temp gun(gauge).I'm interested in how fast this truck really goes..it is fast.

OptimaMan

01-07-2005, 01:51 AM

Isn't stock 18/66? Yeah, I'm extremely interested too on how fast you guys are going also.

According to their numbers, it's slightly less than 400 watts though. I can't imagine 400 watts of power really pushing and emaxx over 40 mph. But, I could be wrong.

From my experience, it seems like you really need about 1 hp (750 watts) to truly get into the mid 40's in an emaxx.

I'm not in any way bashing the Novak system. I actually like the SS5800 for what it does at that price point. I've never seen a HV-Maxx motor - but I'm thinking it's similar to a C40L series or Lehner 1530 motor. Kind of a long "small block" motor.

Anybody willing to open that motor up and measure the magnet diameter and magnet length for me?

glassdoctor

01-07-2005, 02:03 AM

I've been wondering the same thing... size of the rotor, etc. compared to other motors.

The HV is really long... almost as long as a B50 XL, but a bit lighter.

I haven't picked up a new controller yet for my buggy, and I'm considering being a guinea pig and getting a HV if good reports keep coming in.

The problem I have with it is the weight... the motor and esc are HEAVY.... 4-5 oz more than my 8L and Hacker esc.

Signats

01-07-2005, 11:56 AM

If you download the instructions for the HV-Maxx, from the Novak site, the specification for the controller power is 525 watts when used with the included fan ;)

kufman

01-07-2005, 01:16 PM

Hmmm not a real good sign that it needs a fan to do 525W. Not that that it is bad, it just isn't going to be a beast of a system. If it is realiable, that will be a good thing.

pinolelst

01-07-2005, 01:26 PM

Why even build Heavy duty system that only has a power output of 3/4 HP and have to use a fan for ??
The typical nitro engine used to power similar small block sized trucks has somewhere well over 1 HP ??

I know for larger electric airplanes we use a scale of something like 50 watts/lb for level flight and 100+ watts/lb for aerobatics and vertical flight.Is there something similar for land based vehicles...I guess gearing would come into play but is there some ball park figures for acceptable performance in watts/lb for various platforms ??

OptimaMan

01-07-2005, 06:08 PM

That's pretty cool - cars have similar performance needs. I believe 50 watts per pound would be "sport" performance. 100 watts per pound would give great performance! 200 watts per pound would give insane performance! My TC4 is in the 200 watts per pound range and it takes off like a bat out of hell!

Unlike planes, cars are not continous power. 200 watts per pound is under acceleration which is quite often.

SpEEdyBL

01-07-2005, 10:24 PM

I think the high wattage ratings for most of the other motors on the market are a little misleading. Most of the time, the motor's rating is "power input," not power output. Take the lehner basic 5300 for example. It has a power rating of 700 watts at 55 amps. 12.7 volts is needed to reach 700w power input, which exceeds voltage limit anyway. Since the motor would be 80% efficient at best, 560 watts power output is what you would expect at that voltage. By the time you're running within the voltage limit, which is about 10 cells, your only getting 495w max.

Novak's power ratings are measure the power output so it will sound like less. Who know's what the power input could be. The 375w is measured at 14.4 volts. On 16.8 volts, it should be around 510w power output.

I don't think you need 1 horse power to run a monster truck. Isn't 1 horse power supposed to be comparable to the power of a horse? There's no way a 8-10 oz motor is more powerful than an 800 lb animal. Have you ever tried those bicycles in science museums with watt meters on them? Bet it's not easy to reach the 500w mark. It would be kind of silly for your palm sized brushless motor push you and your bike faster than you could ride.

that is a very good observation SpEEdyBL and yes; the horse power measurement is the ammount or rate of work that can be done by a horse. a BL motor pushing you faster than you could ride, no way. not with the gear reduction required just to make you and the bike move.

OptimaMan

01-08-2005, 12:06 AM

Actually, 1HP is approx 750 watts, it's also 550 ft lb/sec. So, if you weigh 550 pounds and can go up 10 feet in 10 seconds, you actually can have a burst of energy equivalent to 1 HP. Or, if you only weight 100 pounds or so, you'd have to climb 55 feet in 10 seconds.

Horses have more than 1HP, but 1HP is 1 horse just casually pushing along on a "treadmill" of sorts. I'm not exactly, but I faintly recall some form of merry-go-round that was tilted sideways a little. A horse would walk around on it chasing after the grass and as a result of the wheel being tilted, the horse would be stationary and the wheel would spin. I believe that's how they actually put a number to 1 HP originally... mabye I heard wrong. Not sure on this one. :)

Those power ratings you see on Lehner Basic motors are peak power for intermittent times from my experience. Typically, running a Basic motor even at 150 watts for extended periods of time with little cooling air will tend to overheat!!!

With proper ventilation, I believe most motors are pretty good at 1/3 to 1/2 their "peak" power ratings for almost continuous use.

A 5 minute run on 16.8 volts with 3300 pack - the pack is giving out approx 500-600 watts continuous!

Testing out my Emaxx/novak B/L in the basement and stripped the orginal universal joints in seconds and center joint warped. It's probably due because i've converted to a wide maxx but there isn't any excuse for the center universals. Luckily I have 2.5 joints on standby but I need 2.5 center joints.

It's much more powerful than stock and will see how fast it'll run in the warehouse tommarrow with the radar gun :D

glassdoctor

01-08-2005, 01:49 AM

gixxer, the center shafts will twist easier than the rear ones. You probably should go ahead and put CVDs in the rear and rear center shaft.

My emaxx has done ok with stock sliders in the front half of the truck. They are twisted some, but haven't snapped or anything. Actually, the front "center shaft" I reversed so the twist in the slider is the opposite direction. I think it's stronger than a straight slider.. it should resist any more twisting. I hope you know what that means.

For example, if both rear sliders are twisted a little, take them out and swap sides. Now the "twist" is reversed. I think they will hold up better with this twist than a new straight one.

LMK if that makes no sense. :)

BTW, it's good to hear the Novak is impressive compared to stock... again.

gixxer, the center shafts will twist easier than the rear ones. You probably should go ahead and put CVDs in the rear and rear center shaft.

Where to buy CVD's for the center on the E-maxx. The T-max uses 5mm and emaxx 6mm correct?

Do you have the 2.5 widmaxx setup? I've changed the U-joints on the axles and thinking about buying the stock 2.5 center joints. It is a little larger but I really dont' know if it stil twist.

Have you checked with RD Logics on the CVD's Their prices are way cheaper than the MIP ones,I have a full set on my Savage and they seem to be holding up fine(I have had no problems with them)The ones on my Savage have an extra set of holes for the pin,so when the pin starts to get some slop in it you can move the pin to the extra hole and get more use of of your CVD's,the MIP ones only have one set of holes for the pin.

Sorry guys no accurate speed test yet. The warehouse is too small and my Panasonic ultra metal are brand new. 1st year goes 23mph. and I can't get full speed on 2nd. Under low power last (1-2min) when it became for controlable in the dusty warehouse the truck ran 28mph. It's really hard driving straight and pointing the radar gun by yourself. When the snow melts i will get an accurate reading.

Oh, forgot to add - the "formula" typically is that 2nd gear is only about 1.5 times for moderately geared setups. If you gear really tall, that ratio drops to about 1.4 times the first gear speed.

Anybody willing to open that motor up and measure the magnet diameter and magnet length for me?

Rotor diameter 14mm, but it has a metal sheath around the outside of the magnet. I would estimate that the actual magnet has about 1/2" of diameter

Rotor length: 44.5mm (1 3/4")

Inside the can the shaft is 4.5mm (3/16"), outside the can it is 1/8".

The endplay shimming much better than any of the 5800s I have owned or looked at. :) very nice!

The included heatsink for the motor is massive, around 75 grams :eek:

The fan is extremely quiet, it hardly makes any noise at all :cool:

Can't wait to run it outside and do some GPS speed tests.............

Anyone see that Supercross on ESPN2 today? WOW! :D :eek: :p

gixxer: In my experience, you have to hit about 28-30 mph in first gear to truly be able to hit 40 in second gear. From my mathematical "guesses" and charts of speeds on my emaxx, I'd guess in second you are most likely hitting about 33-35 mph in second gear.

Get a tripod and mount the radar gun to that and get some zipties and ziptie the trigger for the radar gun. Just be sure not to hit the tripod with the truck!!! I did that any my brand new bushnell radar gun went tumbling down the street about 50 feet... all beat up... but it still worked! That's pretty tough huh?

maybe its going faster than 28? He claims he has a hard time controlling it going straight thats usually a good indicator of a lot speed. So it has to be faster than a stocker with 14 cells. I know on matched 14 cells my truck is still going straight pretty easy and from the videos we all used to like to watch of Hiamps hitting 50mph he had a hard time maintaining a straight line. Im probably wrong since I only ran a dual SS5800 in my truck so not much experience.

that is a very good observation SpEEdyBL and yes; the horse power measurement is the ammount or rate of work that can be done by a horse.

for horse-Power:

a race-horse can put out for short periods about 35hp !!!

a typical horse can put out for short periods around 20-25hp

I don't know it could be close. How fast is it with stock 14 cells?

You have to understand the warehouse is so fricken dusty and spin out when i full throttle it. Outside I can get a very accurate reading and probably take 6 accurate reading to verify the speed. It's just so wet and so much snow here that I can't test out the speed :( .

Anyways, i just order some MIP center CVD for E-maxx. Found some on Ebay. Are you guys buying RD Logics off ebay so should i get MIP? Probably only the rear is needed and I hope the emaxx tranny will not break.

I will really like to see how fast this novak HV is :D

I saw the HV at one of the LHS today for $279... I almost brought it home... man BL stuff is addictive. But I resisted the urge this time.... :)

Any more reports on the HV performance?

The guy at the store said they tried one but only ran it in the store so far.... still ice and snow all over outside. All he could say is that's very punchy on the low end. But this is not a hardcore racing type place... what do they know? ;)

is any one else having trouble with the motor or ESC running hot with a 14 cell setup? the thermal protection keeps comming on when I run in second gear for prolonged time. it is geared 19/70 I was thinking about going to a 18/70, any sugestions? other than a fan mounted to the motor.

there is only one fault with this system, when the thermal protection comes on you do not have any brakes. you are crusing along and you go to slow down and the truck keeps on coasting at least you still have steering.

How about trying the Novak gearing suggestion (from the gearing chart in the instructions) of using 14-16 pinions with a 70 spur gear?

Horsepower is officially defined as "the amount of energy required to lift 550 pounds, one foot, in one second."

# 1 horsepower is equivalent to 746 watts. So if you took a 1-horsepower horse and put it on a treadmill, it could operate a generator producing a continuous 746 watts.

# 1 horsepower (over the course of an hour) is equivalent to 2,545 BTU (British thermal units). If you took that 746 watts and ran it through an electric heater for an hour, it would produce 2,545 BTU (where a BTU is the amount of energy needed to raise the temperature of 1 pound of water 1 degree F).

# One BTU is equal to 1,055 joules, or 252 gram-calories or 0.252 food Calories. Presumably, a horse producing 1 horsepower would burn 641 Calories in one hour if it were 100-percent efficient.

thanks I was heading that direction however I have the HV box and instructions packed away in storage did not know how far to go.
