That is why I suggested the 2200 motor. Using Mike's 2 speed adapter he should be able to get the correct gearing to do about 40 in 1st with 4s and maybe 80+ in second gear on 6s. If they have some sort of smaller 2nd gear spur that would be a good choice to get max speed. And the 2200 motor will have enough torque to pull that gearing without revving too high.
That is how i would do it... I am still working on the 7h scale spped car with the 2 speed in it. Planning on running a 1800kv kb45xl motor on 6s lipo. I had mike bore one of the 2 speed adapters to 6mm for use on that motor, and will run 18/25 gearing on the adpater. My 2nd gear spur will be 49t, so should be good for 80mph or so. I just need to get to the machinist to get the 49t spur I found machined out in the center to match the stock 2nd gear shape.
