I'm setup with an Scorpion 890kv 170 main 14t pinion. I want a 13t pinion for it and the 700 I'm building which also has the 170 main gear, 520kv 14t however I have tried several times to drill out a 13t from 5mm to 6mm shaft with no luck. I'm always a little off center and have a slight wobble with the pinion. I got a 10t and 12t Rhino Gear pinions which would run efficient but the walls are so thin and I've seen pics of the pinion separating and causing crashes. ESC % is in the mid range so the temps can be 165f but it not caused a issue yet. It's not the most efficient setup.
On the 600, whether it be 6s or 8s I've had to put weight in the tail cone for CG.

I need to correct myself. I using the 188t main helical gear with a 15t pinion on the 700. I can switch out to a 170t if I had faith in these pinions
