Ah, just ignore my post. I didn't notice the thread below, and also did some heavy duty googling. Seems the transmission ratio is calculated by dividing the shaft gear by the diff gear (52/20 = 2.6:1), which is then multiplied by the Spur divided into the pinion (80/27 = 2.962 recurring).
These two figures should then be multiplied ( 2.962 x 2.6 = 7.701 ).
So I should input 7.7 into my esc programmer gear ratio field? Hope this is right.
