I've been running my V2 using the internal UBEC with no problems at all.

Sounds like you need to lower the gearing some.

if after lowering the start setting with the ESC and its still too hot try lowering your gearing( smaller pinion, bigger spur)

Mine too

lol my v3 works fine :)


adding an external BEC doesnt fix the problem, only hides it... it may have been proven to lower temps in esc's with a linear BEC. a switching BEC creates almost no heat.. But since you have it all under control i will stop talking..

I think it is crazy that he thermaled a MMM.

[Joram]

haha, lol

It was not thermal shit.... Just a empty battery

But i assume it is normall then that the fan spins when the cut-off is working???

Did today some bashng with no problems, only fried AGAIN the stupid slipperpad:S

if your slipper is too loose, it will create more heat for both the motor and the esc. if you kept it a little tighter, it would help.

[fastbaja5b]

The flux slipper you have to pretty much tighten it up, even going 1/4 turn out and red loctite on the bastard it'll still come loose.

[Joram]

You don't wanna know how i have tighten the slipper up....

It is almost inpossible how tight it is, with blue loctite on it and that helps...

But the slipper just smokes... Spur becomes hot and i have a lot power so the pads burned away, i saw smoke from the car coming

I'm now using that bycicle repair stuff, what you can cut in you own way!
It is very sturdy and i make it fully covered.

Not only as a normal pad, but also in the middel around the shaft. Just make a round one and cut the hole for the shaft...

I hope you understand this what I say


I am also working on a mountingsystem with no slipperpads, so directly the spur to the shaft...

You'll want to keep the slipper no matter what. If you bypass it your magnet could come off the shaft in your motor on a bad landing. The slipper is there for a reason. A different pad material is probably your best solution.

Riley- why have a slipper? Buggies and truggies don't have slippers, and I'm sure many other people (as well as me) have had plenty of bad landings without their magnet detaching.

It can happen. It is also a little more important on a mt because there is more weight and larger tires being thrown around. I guess you could go without it, but you run a much higher risk of ruining your motor. It may not happen to everybody but you may just be the lucky one...

[Joram]

I think that there is an very low chance to ruin you motor with that...

Today my slipper was again the troublemaker... I'm going to screw the spurgear to the slipperhub with 3 screws, threw the spurgear. I drill the holes and use soe bolts with nuts.

I've everything on my truck bullterproof with the highest quality, but only that piece of ***slipperpad

sounds like its time to rebuild your slipper clutch
