the big thing I'm worryed about with mounting it back that far is that area is allwase filled with dirt and crap...

what if I mounted the esc on the novak battery strap??

wouldn't having the RX over the servo and the esc were the RX is be far enough apart?? the power wires would be going over the motor to keep them from geting chewed up, and the motor wire arn't that long...


just thinking outloud here, but I can flip the motor mount around and have the motor facing the other way, the spur clears the chassis, and the motor is moved slightly to the servo side, my main worry would be the motor clearing the body, but I could alwase cut a hole and get more air over the motor, then move the esc to were the motor is now via plate between the batt boxes:neutral:

I guess I will play around with it when I get the motor in:whip:

I would put the esc in the back. You can make a small mudguard out of some scrap plastic to keep the dirt out. If you put the motor in the front it will stick out of the body and the first time you flip it over you may damage the motor and mount.

WOT!!! my motor came in today!!!:yipi::yipi::yipi::yipi:

I lil on the fast side, but I'm only driving in an open field right now.


did I enter the amp draw right?? 1000 cont. watts / 14.8:neutral:

after its madin voyage, I have mixed fealings...

the pinion is a PIA to get on and stay on, I hope grinding a flat spot on the shaft solves this...

the esc gets a little hotter that I would like, 6(i think) LEDs after a 15min run, but yet the case wasn't hot to the toch and the hotest temp I got was 165 off of the solder posts. any sujestions on colling it down??

COGING!!!!:grrrrrr::grrrrrr::grrrrrr: its only a little going forward, but I can't back up at all, it just stutters:grrrrrr::grrrrrr:

OMFG I have POWER!!!!:yipi:

its at the track right now, so I'll get pics tomarow, but I realy like the way I layed it out

still sounds like a chainsaw...:whip:

anyone??/

Help with what? Cogging? Try changing your settings.

yes, but IDK what to change, the timeing is a 0, the current limiter is off, and it only cogs trying to back up

You timing can't be 0. Change it back to normal. That should fix it... Why the heck did you set the timing at 0?

the motor is a neu 1512 1.5d so its non adjustable timeing on that, nothing changes when I set the timeing to 5-15%

anyone know were to get the RC8 plastic spurs???


I think i found the prob, the CC bec is only set at 5.1v from the factory....

If it only cogs in reverse, what is the issue? It doesn't really matter in reverse. If you aren't overgeared I can't think of any more problems. Change all your settings backs to stock. I don't want to be mean, but if you set the timing to zero you probably set something else wrong...

I would see if your lhs carries or can order in rc8 spurs... It would be way faster and probably cheaper then ordering online. If they can't get any in, I guess you could get one on tower...

it doesn't GO in reverse, it just stutters(coging) and goes nowere

Would you mind posting a picture of your settings? If it isn't your settings, the only thing that comes to mind would be binding. Push the thing in reverse and see if it rolls as smoothly as forward. You could have a drivetrain problem.

What radio are you using? Sounds like you may need to zero everything to do with the throttle channel and recalibrate the radio to the esc. I am not familiar with tekin products, but if it works one way and not the other you may have a controller issue. Do you have the reverse % set very low?

its a JR XS3(75mhz fm), it has the same functions/adjustments as the spektrum DX3 without the whole spektrum thingy. I'm 100% positive that the setings on the controler are right...


the drivetrane isn't binding at all, so thats not it.





EDIT: I found the problem, the CC bec is set at 5.1v from the factory.:grrrrrr:I hooked up the esc without the external bec and problem solved...

anyone have a castle link I can barrow?

How is your bec causing the problem? If the esc works witout the bec then I guess it doesn't matter.... 5.1v is perfectly acceptable.
