Been a long time!...Need some Guru input.

I'm sure the mount will work.

Gear mesh = the space between the pinion and spur gear, how the teeth of the two gears "mesh" together.

Do you mean gear ratio? Like the tooth count of the gears?

Rc-Monster has pinion gears, just look under Rc-Monster parts.

I have notified the owner of Rc-Monster (Mike) of this thread, he should chime in on what battery tray to get.

For 4s use in a buggy I recommend the Castle Mamba 2650kv setup. Plenty of power and insane speed when you want it.

Tell me what you want to do with the buggy (bash/race/speed runs) and I can recommend what tooth count you want for a pinion. (gear ratio)
