Converting my CRT .5

[BrianG]

Welcome! Your setup sounds almost exactly like mine, except for the conversion kit used (I made my own mount, ESC/rx tray, and batt tray) and I stuck with stock size tires. I think you'll be very happy with your proposed combo. As far as gearing goes, I have mine using a 14T pinion, which sets the top speed at around 35mph. Seeing as you are using 2.2" wheels, you may want to gear down a little more, probably 12T or 13T because the larger tires will have a higher roll-out; that will keep you in the ~35mph range.

BTW: There are some R/C calculators (link in my signature) that may help in choosing the right gearing.
