Lipo: Anything 5s? I would say maxamps, trakpower, trueRC- all the well known brands basically. Look for the voltage you want to run, a minimum of 4000mah, and 20-25c ideally. Obviously, the better the specs, the higher the price (true rc does 8000mah 10c packs that would be good; so long as the batteries can cope with the amp draw of the motor, you will be fine).

Whats your budget for motor and esc? there are much more efficient motors available than the feigaos, but with a lower kv rating like the 9xl it shouldnt be in danger of running too hot, especially with a fairly average weight truck- not a 13lb lump thankfully.

I can't spend a ton of money...this is going to be a backyard basher...would it make more sense to go with a 10xl with 5s to keep things cool?

Here is my problem...I have gone the wrong direction too much with this truck by purchasing the wrong esc and a 9L before I really got on this site. I now have a new 9L sitting...I want to do the right thing, only once.

I was looking at the quark monster pro esc in the store, is that what you are referring to or is there another Quark 125?

Soooooo Confused.

Thanks for helping.
