Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use this on older RB7 variants?

It is intended for RB7 and RB7SS specs. Older variants may fit but always verify shaft spacing and mount points before committing to installation.

What pinion size pairs well with 69T?

Pinion choice depends on motor and track layout. As a starting point, test a few pinion sizes to find a balance between acceleration and top speed for your setup.

How to check gear mesh properly?

Set mesh with a single sheet of paper between pinion and spur, rotate to seat, then tighten and recheck. Proper mesh prevents premature wear and noise.
