So I just bought a second hand LCC and it is either setup poorly or the motor is bad. Current setup:

Mamba Max ESC
LiPo 3 Cell 1300mAh
Speed Gems Acronite 19t(?) Motor
16 tooth gear

Right now it has almost no power to climb and runs hotter than a pistol. I honestly know very little about RC motors or crawlers for that matter. Battery is brand new and being charged with a decent charger. I started out crawling and within 5 minutes it is was smoking hot, I let it cool down tried again and got about 2 more minutes and the battery was dead. I am thinking I burned up the brushes in the motor as it now has almost not power and gets hot almost instantly.

Sooo I guess the question is what motor would compliment my battery/ESC setup nicely and give me some decent torque and battery life? (Could really careless about wheel speed) Also not looking to spend a ton but will spend what I have to.

your motor is way off to say the least, and probably has not been taken care of....i smell the smoke from here....most people run brushless, the few people running brushed are running in the region of 35t with very frequent comm lathings and brush changes...that, and its over-geared. you can make a brushed motor work, but you need to take care of it, and gear conservatively, if you're not up for that, i recommend switching to a sensored brushless system. the mamba max pro and tekin 17.5t combo is running very well in my truck with a 14 tooth pinion.

What ghtpdm5 says....I agree..I run a 21.5 on 3S with a Mamba Max Pro and a 14 tooth pinion, it has lots of torque and wheel speed and runs cool.

relic68 · 07-16-2011, 12:29 PM

Yeah...what those guys said

, I personally am running a Goat 3s with a 17.5 ballistic geared at 15t on 3s. It get's a little warm after a 6 min coarse, but I've never had one get to hot to touch.

From my experience with a 19T they dont like 3S in a LCC. If you want to use that motor try 2S with a 13T on it.

If you want to jump to a different brushed then Brood or Holmes Handwound 35T's would be my recommendation on 3S.

You cant drive a Losi like you would a scaler or other rig, they dont like running hard longer then (id say) 10 minutes. The motors just heat up to much.

If you want something you can run for 10-20 minutes (pending battery lasts) then you could try a Traxxas Titan on 3S with a 13T.

outkast7222 · 07-16-2011, 10:03 PM

Thanks for the reply's everyone. I went to a few shops today looking for a brushless motor and there is nothing local to be found. Sooo I did some online searching and ordered a motor that way. But for the time being (since I really wanted to play around some) I picked up a cheap 55t Intergy and a 13t pinion. Seems to be working pretty good, has way more power and after a 10 minute beating I can still touch the motor with out receiving burns.

This leads me to my next question: Is 10 minutes a reasonable amount of time to run on a 1350mAh battery? Should it be much better when I go to brushless?

2500hdon37s · 07-16-2011, 10:10 PM

yes you will get longer run time with brsuhless as they are much more efficent.

I am running a 18.5t Novak goat system in my LCC with a 1050mah 2s lipo, and a 12t pinion and its great! pleanty of tourqe, right amount of wheel speed, takes a while to get warm, adn i can get up to 30min out of a 1050mah pack.

OOHHH so true EeePee

ghtpdm5 · 07-16-2011, 10:17 PM

for runtimes with my setup, i get about 45 mins of bashing it, driving decently hard. last comp i only went through 2 1000mah batteries in 3 5 min courses (driving HARD) and quite a bit of bashing practice.

outkast7222 · 07-16-2011, 10:28 PM

Hmmm makes me wonder if I have something else going on that I am overlooking. Or is there really that much difference in run time between the two? 10 minutes is really pushing it right now.

ghtpdm5 · 07-16-2011, 10:38 PM

chances are the axles could use a re-grease too. i had piss poor runtimes with the lnc trans on brushed, a 3000mah nimh would get all of 30 mins on it.

outkast7222 · 07-16-2011, 10:59 PM

I did notice the rear axle was a bit warm after running it so I will have to rip that down. Front one was cool as a cucumber, but will rip that one down while I am at it.

How do you guys adjust your slipper clutch? I noticed that this one was setup with it tight to the point it didn't slip even when bound up.

Supermanjrp · 07-18-2011, 09:33 PM

Why do yall not recommend brushed motors? Im bout to put two HH 35t motors on my moa conversion losi.

ghtpdm5 · 07-18-2011, 09:39 PM

moa conversion is completely different than a shafty losi....the friction of the worms and the huge reduction means running the motor at high load and rpm while running. the moa gearing is different and also only pushing one worms worth of friction.

I have the hh sport in my losi moa and I love them I have mmp on 3s great great motors buttery smooth

outkast7222 · 07-19-2011, 02:08 PM

Well the place I had ordered my motor and ESC from called me this morning to let me know they couldn't get it in for at least two weeks.

They had no explanation. Everyone else seems to have it in stock.

Was planning on the Goat 3s 18.5t. So I have the option now of running down and ordering something else. Sooo anyone got a recommendation of what to get for about the same price point? Or am I just better off ordering the Goat from someone that has it in stock?

flyinfatkid · 07-19-2011, 02:30 PM

I have a goat 2s 18.5 ran it on 3s never got hot and tons of wheel speed! But it's not recommended. Voids warranty also! But very capable motor/ esc

outkast7222 · 07-19-2011, 06:35 PM

I am starting to really second guess ordering the Goat, after lots of looking around seems there has been a lot of failures with them. Is this something they have gotten figured out? (Most of the posts were from 2007-2009)

ghtpdm5 · 07-19-2011, 06:46 PM

imo, novak esc's are over priced for what you get....very much so, and the fact that you can't run another company's motor in them and still have crawler instant reverse (there's a resistor in the motor that id's it as a novak crawler motor, without it, the esc will only run in double pump reverse). combine that with novak's iffy at best customer service, and theres a reason that the only thing novak in my box is a set of pinions. the mamba max pro is the best bang for the buck.
