ME-student, I apologise if I get the wrong message above but if you read my other post in this forum, you will know that I'm not short of knowing what internal and final ratios are even though I'm still a newbie.
Since I do not own an MTX-2 (much less MTX-3), I do not have any clue as to what the internal gear ratio is for the MTX-3.
I have assumed that the figures given by Robbie in his earlier post was the final ratio of the car when using 22T/42T gearing. My bad. In any case, thanks for clearing it up. No biggie
