My first nitro to brushless conversion!

[Superbasher]

I'd probably leave the upper deck in as it mounts the servo to it i take it? also i'd probably keep it so i could put the reciever where you have put it, i was thinking of modding a hot bodies radio box to it, but then i thought forget it when i could mount it to the upper deck. So 12 teeth is the ball park figure then, even if it turns out to be a bit undergeared. My T4 is slightly undergeared as of now, but it still amazes me how fast it is on 6 cells.
