Ill look in to that for both of my TP motors as they have 8mm shafts.
I only have one 1/5 scale and the K8 uses Mod 1 gearing so I wasn't familiar with mod 1.5
I was reading something on another forum today that mentioned something about mod 1.5 gears. Is there such a thing and what scale is that used for? I've not heard of mod 1.5 before
