I read somewhere (one of the mamba manuals perhaps?) something that basically said that brushless motors will use all the power you can throw at them. This agrees with my experience with brushless systems - it implies that either your batteries or your motor is going to be overloaded and overheating - and thats a full throttle - if your driving around half throttle then your esc will just cook. That follows my experience pretty well. If I put some crappy batteries (3s 3000mah 15C) in my rustler it doesn't go very hard and batteries will cook. If I put some relatively good (3s 4000mah 25C) batteries in, the batteries barely get warm, but the esc and motor cooks.

Does this mean you have to match your batteries with your esc/motor combo as well? and according to people here there is an optimum gearing as well, so then you can't change gearing or something will overheat? that doesnt sound like theres a lot of versatility in these systems? something just doesn't seem to add up right right... I don't want to spend $600 on a brushless conversion to have a truck that I have to stop and check temps and let cool down every 5 minutes.. I crave the power of brushless in my truck, but to me nitro engines (although very messy and expensive to run) seem so much more versatile and reliable (or have been in my experience anyway...)

Basically I guess is there a balance with brushless/lipo combos? If I run quality nimh packs in my rusty then nothing overheats and its got nice controllable power good speed and is fun to drive. If I put lipo's in, either it goes like a dog and the batteries cook, or it absolutely insanely overpowered to the point where you can't give it full throttle without it swapping ends or flipping, which usually results in the esc overheating trying to limit all the power from the batteries, or if u let the power through the esc, the motor cooking from dealing with all the power..

Sorry bout the long post guys :P I hope I'm kind of making sense.
