I've had good luck with the HXT 12kg servo. It has enough torque to turn my e-revo wheels on cement and it has metal gears, a lot of torque,,, It only costs $8. Just make sure to use washers and be careful with the mounts, because I've broke a couple. If you have a solid mounting point like most vehicles do and you use washers you'll be fine.

there is a reason why the kd 36 is known as turning toasters of death... the kb 45 is not high end yet, but at least has a balanced rotor. and In my opinion they get hot, but not that hot like the kd. make sure that you can install some fans for cooling purposes, the normal heatsinks don't fit. maybe a losi heatsink fits, dunno. some boat guys drilled holes into the front and endbell, so the heat gets out easier, I did that as well, and made it dustproof with a nylon-sock. however, make sure you have a proper cooling for that motor, otherwise - when it turnes too hot inside - the rotor is demagnetized. and that can happen pretty quick...

the shaft is 6mm, most of the pinions are 5mm, so you have to get the shaft done for 5mm. or you buy a bunch of pinions and get them drilled for 6mm. you won't be able to do that with your drilling machine.
