What spur do you use then for the Mod1? I was thinking of using the strobe + 51t ofna spur...... also is it of to run the tranny backwards? the reason for me asking is if I use the motor mount, this will reverse teh rotation of everything right? this would work perfect for me cos I have a nitro supermaxx and the diff spins bacwards on a nitro truck....... Im buiding this brushless right now and I dont even have anything yet but teh suspension and transmission, if the tranny can run backwards, then all I have to do is switch chassis....... thanks
