I didn't modify the tranny at all.
It's a 18/61. I had to move the controller to the front or the wires wouldn't reach. I think they're less than 4". I'll check again after school.

I ran it 4 more times, and it overheated every time. At about half-pack, it just shuts off, waits 5 seconds, and then comes back on. Then I drive for 5 more, and it does it all over again. Quite annoying. I have the fan on, I don't know what else I should do. Also, all the heatshrink on the batteries melted off

Look for the same thing as with a standard motor.

- Maybe your ratio is too low (big pinion)

- Maybe your drivetrain is not free enough

- Maybe your pinion is too close to your spur gear

etc.

what is the amp rating? e-maxx should have atleast 100amps controllers

k_sw31 · #**405** 09-12-2002, 09:40 PM

Even the stock drivelines?? From what i've heard, i wouldv'e thought they'd fall apart.

Btw, maybe you should try it in your bolink

OK Soya
The brave Schulze seemed to do its job under hard conditions ... so the melt-down of the heat-shrink -> STOP USE THEM THAT WAY

To have an idea, heat-shrink comes to melt down only when Amp is too huge (I think about it) OR a short is coming between cells polarities and the pack heats (often due to following poor stock bridges)

I really come to think your Motor is overgeared ...
--What sort of duration did you get ? (please don't do it again !)
If you're not in parallel, count 3min total (goes and stops) along with 2000mAh is BAD ...
-- You didn't talk about the motor : Does it also heat critically ???

Another common issue can be :
1/ pb in the gear train -> Make it turn manually from each wheel w/o the motor ... Must turn freely w/o any hard point ... I say that 'cause I recently broke a teeth with my BAD Spd700Neo Outrage truck and hardly found the cause ... The ESC (Schulze) was the first to work strangely (I was right !)

2/ Wrong motor setup with the ESC ... But you note quickly strange handling and bad control ... (obvious to find)

What?
The motor's temp is fine with that big ol' heatsink. It can't be wired wrong, it either goes forward or reverse, and the middle one stays. I'm using the stock gearing. Run time wasn't too long, probably because of the cheap Peak packs. Pinion-spur mesh is fine; a bit loose if anything. I think I'll put it in my rally car next....

Popop · #**408** 09-13-2002, 05:00 PM

Did you also run it along with serious batts ??
(means both good cells and good wiring)

#**409** 09-13-2002, 05:37 PM

The wiring is good, the batteries WERE good....

Hey dudes I got the hacker/shulze system right now and its got too much power. MY TC shoots out SOOOOOO FAST!! I cant belive it, and my e-maxx does wheelies on command. If I didnt need money I wouldnt be selling this brushless system EVER!, if anyone is looking to buy mu brushless e-maxx look at my post in the BST forum. I just now charged a 1500 pack and ran my TC for 10 min without the ESC getting hot, but I did zip tie a small heat sink onto it, in my e-maxx it gets kinda hot. Also, anyone ever melted a tire? I just tried to see how hot my tires would get, i held my TC in place for 5 sec and i burned myself when I touched the tire and then little rocks got stuck on the treads after I stopped, a full throttle acceleration took those all off, but it left fill tire marks for 5 feet on my wood floors in my room, I shoulda taken pictures b4 I paniced cuz my mom got home...

Bolink! Bolink! sorry, i'm just ready to see a bolink go into orbit.

gixxer · #**412** 09-13-2002, 08:51 PM

Forget nitro!!

I have the aveox setup and my Losi Lx-t truck goes 38-41mph with a 37/84 gearing on the old trans. Slipper wouldn't hold with that gearing so i'm going to convert it to the old JRX-t type "no slipper" and then the 32 pitch 27/54 combo.

Simply awesome with only 6 cells. It'll probably get 50 mph with that gearing and who knows how fast with 10 cells.

And yes all my speed is recorded with my radar gun and my mp6 inferno with 13T clutchbell and Os V01B only goes 38 so my stupid electric truck is faster for the moment.

k_sw31 · #**413** 09-13-2002, 11:14 PM

what kind of run time do you get?

Can ya lift the wheels pretty easily with that gearing?

#**414** 09-13-2002, 11:38 PM

I just put the BL stuff in my rally, but the reciever pack isn't working, perhaps I'll borrow my friend's reciever....
I need new tires for the Bolink; they're shredded (not to mention the car's in several pieces

). Alas, I have no money

#**415** 09-13-2002, 11:47 PM

Oh, about that tire melting thing. When I first got my D4, I put it in my rally. At the time, I had Proline LP2 slicks, and 4-TEC shocks. I set it on my front walkway, and yanked on the trigger. It left tire marks for about 6'. Wow, did that thing have power. Perhaps I'll post a pic tomorrow.

k_sw31 · #**416** 09-13-2002, 11:50 PM

wow, six feet of tire marks, sweet, i'll have to get some slick for my t3.

#**417** 09-14-2002, 12:15 AM

It was weird. I did it like 10 months ago, and the area where the streaks were is brighter than the rest of the sidewalk

k_sw31 · #**418** 09-14-2002, 10:47 AM

maybe you should start a street cleaning company, lol

#**419** 09-14-2002, 11:05 AM

Riiiight

It's kinda hard to see in the pic, but it's been there for almost a year

#**420** 09-14-2002, 03:18 PM

Here's my setup for the rally. It still overheats, I've tried changing the frequency, still doesn't help, I still don't know what's wrong

rawbert · #**421** 09-14-2002, 06:51 PM

Guess what

I just ordered my setup - Aveox RC7 and L160RC ESC.... I can't wait!!! It's going in a off road truck, so I will tell you how it is next week!

k_sw31 · #**422** 09-14-2002, 07:26 PM

maybe you should try running the motor w/ out a car, see if it still gets hot that way.

#**423** 09-14-2002, 07:29 PM

Yeah, good idea.

k_sw31 · #**424** 09-14-2002, 08:43 PM

hey u guys, i was thinking, should i pay the xtra ten bux for the lehner 70 amp esc for better brakes, or would 40 a be fine?

SandManRacing · #**425** 09-15-2002, 01:37 AM

I think you should go with the 70 AMPs. Better go higher than lower. A brushless motor in a car or truck draw between 50 and 65 AMPs I think. I have read about that somewhere...
