CHEAPER Brushless Motors FOUND For conversions!!!! [Archive]

So, it seems for the moment, feigao was the only company making cheap brushless motors worthy of 1/8 scale conversions - untill today, i stumbled across some VERY cheap (about 1/2 the cost of the feigao (assuming the feigao is $50.00)) motors, with a 5mm shaft and good spec:

Here (http://www.hobbycity.com/hobbycity/store/uh_listItems.asp?hotDeal=&orderBy=recently&strSearch=&idSupplier=)

The good news is, obviously the price - Only 26$ per motor! a 5mm shaft and also 540 size motor (obviously). furthermore they are able to cope with up to 5s and pull about 60A, so same sort of spec you would expect with a feigao but about half the price.

The bad news comes here, first off, they are only 60mm long (about the same size as the feigao 540L and similar to the NEU's they have gaping big holes on the front of the can. im also guessing they need to be clamped to stop them falling appart. Last bit of bad news is that in the biggest size (60mm long) they only come in 1200Kv (too low) 1800 Kv (about same as a feigao 9XL) and 2600Kv (TOOOO high) ratings. at least, for a truggy...

i reckon for an E-maxx running 4-cell, you have found gold with these motors!

for a truggy, i will let you know soon :D

Let me know what you think, i will post my findings as soon as i can.

take care,

they look ok but in reality you get what you pay for meaning they will most likely run a lot hotter than the higher quality around.

yes they are a 10th of the cost and would be almost disposable. But in the long run a decent quality motor like one of the german made ones or the neu motors more than pay for themselves with the time saved with changing out cheap motors when they cook themself to death.

Also the bearings are so much better quality meaning you hardly ever have to oil them on the high end motors whereas you have to oil the feigao bearings very often to keep them running smooth unless you change them out.

to be honest, other than bearings, nothing wears out in a brushless motor...strength of the magnets also do depending on the age.

im willing to give this one a try, if it works out, we have another motor for those who are on a tight budget...

If the motor runs, just very hot, so be it, slap a few large heatsinks onto it, be a little more conservative with gearing and run it anywho, if your on a tight budget and just want to get bashing, it could be ideal.

Take care,

actually the 2600kv and TURNIGY Plush 100amp Speed Controller would be a very nice light revo conversion for around a 100$, you can not beat that with a stick

Demon-TC3

03-16-2008, 05:17 PM

Indeed, im not sure about the 100A esc they have, very high Voltage, bought one for a friend and he wants to use it in a savage conversion, we can program it to work as a car radio should (i.e neutral is at 50%) but not sure how it will start it moving since its a "Soft start" esc...for planes...

will probably work just fine to be honest.

for the moment, i want to try this thing on a BK 9920 and a MM esc on 14 cells. if its all good, will let you know.

take care.

yeah I ordered 2 2600, for a dual mambamaxx emaxx project should move my supermaxx good

I guess it's enough "air" to breath on until the MMM comes out. The 2600 has the same specs as a feigao 9L, which has decent power in buggy. Still, I would rather have my novak hv4.5 motor than any number of feigao motors (if I couldn't sell them). TBH, I've never been able to complete a run with my 9l without it overheating no matter what gearing, and it runs hotter on 3s than it does on 4s.

Hey which one is the 540 ?

pcnutz

03-17-2008, 08:00 AM

if the 2600 is 4 turn? does it have more than 2 pole?

suthernboy08

03-17-2008, 08:51 AM

Is the 2600 a 540 sized can?

pcnutz

03-17-2008, 08:54 AM

the bottom 3, 2600, 1800, 1200 are 540

Demon-TC3

03-17-2008, 09:49 AM

yea, the 1200, 1800 and 2600 are all 540 sized cans (same as Feigao 540L cans).

strange, my feigao has NEVER over heated. warm and once hot (was pretty much crawling up a steep hill :P) but its been perfect.

i may have to give one of these a try though...

take care,

I saw someone say the 2600 was to
small what do you mean to small?
Will the 2600 be to small for a staduim
truck with 3s if so how? Need to know
before i buy. Or will it kill my batt?

suthernboy08

03-17-2008, 01:54 PM

Im sorry demon-tc3 i miss understood
So will the 2600 be enough power for
my staduim truck and 3s battery or will
it kill my batterys? Im thinkin about
buying one of them.

Demon-TC3

03-17-2008, 02:31 PM

they are really for 1/8 applications because of the 5mm shaft, they are the same size as a 540 can (a bit longer but mount anywhere a 540 would) and if u can get a 5mm pinion they will fit just fine.

on 3s that thing will HAULL. you will have more torque than u kno what to do with! as i say though, make sure you have a 5mm pinion.

Take care,
Demon

suthernboy08

03-17-2008, 02:55 PM

What is and where to buy 5mm pinions?

Demon-TC3

03-17-2008, 03:00 PM

a standard motor has a shaft 3.2mm in diameter, that is what a standard pinion gear is designed for. the shaft on these motors is 5mm and hence you need a pinion wiht a 5mm shaft to work with it.

To be honest i think you would need a different motor in a 1/10 application, either that or you need to turn the shaft down to 3.2mm. i dont think they make standard 5mm shaft pinions (48dp).

take care,
Demon

there is one thing i don't get?!

how come that it looks like, a lot of people involved in R/C are cheap or broke?
seriously. i used to motocross, that cost me thousands a year. i used to scuba dive, cost a few grand a year. mountain biking, **** brakes all the time...and so on.
if you get yourself into this hobby, prepare to spend a few bucks. how many motors do you need? if you would need 5 or 10, i understand. but you need for each model only one motor! if you already spent 500 for a revo, 400 for a nice Transmitter, upgrade a bit here and there, charger+batteries...the motor is least expensive item!!! unless of course you get yourself a hacker, lehner, pletti or neu...even if you do, they are worth it.
believe me, you feel much better knowing you got a super nice motor, even if it did cost you 200 bucks, than getting one for 26dollars! you get what you pay for. period.
plus: this hobby is like everything else. its there to waste money and enjoy.
and by the way: i am not loaded...believe me.

p.s. i hope someone thinks the same way and i don't get a trillion messages telling me to **** off. i really have NO intentions pissing anyone off!!!

Well, to be fair, some of us, like myself (and I think Demon as well) are in college. "Fun" money is a huge scarcity in college. I'm lucky that I have a free ride and get money BACK from all the scholarships I have, but even still, that money isn't able to be spent on fun stuff. I have to spend it on things not covered by scholarships like housing.

Just because I'm a broke ass college student doesn't mean I don't enjoy my RCs though (there's not a whole lot to do here unless you have a car, and I didn't bring my car with me the first year!). And unfortunately, I'm guilty of buying things (with my own money I worked for over the summer) while in school. You can bet I look for the cheapest stuff I can find though (but I don't totally cheap out ALL the time; especially if I know it's a part that will wear out or receive a lot of usage).

I think that's the reasoning (at least one reason) behind trying to find cheaper things like motors.

ElectricThunder

ElectricThunder, i had no idea. it makes totally sense the way you explained it. i am 38. for some reason i thought most people here are my age. don't know why. anyhow. i wonder how old most people are here? if they are my age, they better have a good reason for being cheap. ha ha. what is it? kids? alimony?...

just kidding. thanks for the reply though and not taking it personal.

No problem.

As for how old everyone is, I think there's a huge range of ages on this board. From 13 years old all the way up to at least one member who I know is in his 60s (hasn't posted in a while, though I think he's in the Heli forums more often now).

At 34, I guess I'd be considered an "old" guy here. Still I started this hobby a long time ago when money wasn't as plentiful. Like Some of the college students on this forum, I can remember making that critical choice between a new radio, or a used book with a few pages missing..

That being said, I gained much more appreciation for the hobby when I had to be frugal. Besides, there are many good deals out there now and it's always good to pass the word along to help others.

I haven't had to go that far, but some of my books could EASILY buy me a new radio or brushless setup. My physics book is $240! Last semester, I spent about $700 on books, and this semester, about $500! Between those two expenses, I could have had a pretty kickin' brushless 1/8 conversion. Or a few Helis (I have no RCs that fly, and yet I'm an Aerospace Engineering major- needless to say, I'm getting into planes and helis now also....ugh!).

Oh well.:(:wave::huh:

Just a guess, was that for all three volumes of University Physics or just one?

ElectricThunder

Just a guess, was that for all three volumes of University Physics or just one?

It's two semesters (physics 1 and physics 2). I don't have to take physics 3 for my major.

My Calculus book was "only" $200, and is good for three semesters of calculus (1, 2, and 3, which I have to take all three, and then switch over to a different book for Diff Eq.).

splode

03-22-2008, 03:35 PM

Ok, I just thought is might be one of the old Sears texts sence they are pretty much the standard for freshman physics.
Cool that you can have the same book for calc. I-III. My school was never that nice to us :).

ElectricThunder

03-22-2008, 05:50 PM

Heh, my school isn't all THAT nice. They raised tuition by something like 10%, and then cut the budget by 6% twice in one year, so a 12% budget cut. Books are also going up. I'm sure it's like that all over the country too, but because Florida's "Save Our Homes" tax passed, there's not near as much revenue from property taxes, so of course, they cut the school budgets (I go to a state University).

killaj

03-22-2008, 06:26 PM

Yeah.. the "Save Our Homes" tax did help me out a bit. I'm also a Fort Lauderdale resident and a first-time buyer here in Florida. The property taxes were killer!

03-24-2008, 07:32 PM

hehe hey all,
Sorry was away last few days and took me a while to catch up - nice to see the thread progressing..

Ok, well, reason for the cheap-ness, as ET said, yea some people are tight on cash, partially due to reasons such as education and other expenses, but also (For me at least) that the truggy is my basher, i want a fun thing to bash arround and keep it going at minimum cost - my touring car on the other hand is a different matter, nothing but the best for that. ive spent well over $3,000 on that thing easily, so when i can justify soemthing to be bought i will, but, if i see something with a good spec at about 1/2 the price of anything else on the market (and when i dont need the best) you better beleive im gona go on the cheap :D

I cant agree more that this is an expensive hobby and if you are racing competatively there really is no alternative, but for bashing, i would say its possible ot get away with a $26.00 motor!

Take care all,
Demon

electric thunder maybe you should take footnotes in the book or something. and then sell it to somone going into the class at a higher price.. MUHAHAHA

I need that same book for physics 2. After that, THEN I'll sell it to someone for like, 100 bucks or more (definitely more than I'd get back from the bookstore for this book in MINT condition!).

neavissa123- No problem. It's a good question, and the addage "you get what you pay for" is so very true; RC is no exception.:teacher::cool:

Hey all,
well i stumbled across a new item on UH today which seems to be EXACTLY the same as the Feigao motors - http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=6678

Same dimentions, max current, stall current, idle current, shaft size, resistance and overall seems fairly similar performance wise - at $30.00 seems like its a strong replacement.

Take care,
Demon
