motor mount
 

i have just taken my motor mount off because it is such a pain to swap spur gears,and as i am experimenting i need to be able to change these easily. I am using the stock mount at the moment and just wondered if any one had any idea's or thoughts on this

what tooth spurs and pinions do you have?

I have a hv maxx and novak suggests 70/14-16 so that along with i have a 72 spur and the stock gearing this is what i am playing with at the moment

Why would you want to swap Spur gears? It is much easier to swap the pinion. Once I put a Spur gear in I leave it and change my gearing with the pinions.

i am not the most knowligable person on gearing but i wanted to find out the differences if there were none surely novak would have suggested 66/.....and the only way i thought i would find the difference is by experimenting,if there is a short cut to this knowledge iwould welcome it

There are some other guys on this forum that run the HV. If Novak is suggesting a 72T Spur I would go with that and then you can play with the pinion size. Start with their recommendations and then you can go up or down a tooth size to fine tune the gearing for your needs.

I agree with Frank. I would stick to a single spur and change the pinion for experimentation. Each tooth change on the pinion is equivilent to a 3 or 4 tooth change on the spur. If you change the spur from a 66 to a 72, it is almost like dropping a tooth on the pinion.
