Just after a little advice for Petit R/C next weekend.

What overall ratio should I be looking at for the above combination? I've got a choice of 87 or 91 spur gears.

Thanks for any advice guys.

Dave.

16 or a 17 on the 91

So something around 11.659 / 10.974 then?

I might try 16/87 then as it'll give me 11.147 to start with.
