Hello my friend and I want to convert this 50nx to Electric the gear ratio says it is (( 8.76/1 )) but with the gray counter gear it is (( 8.67/1 )) I have a hacker A40 10L 1100kv with a Electron 80/100 amp esc and 6 cell 5000mah 30c so what would be a good pinon gear for this heli. And Thanks for any help that you guys can give me.

How to find out...

https://rc.runryder.com/helicopter/t626816p1/

RPM = Motor KV x Batt V (3.7 per cell) x Motor Efficiency (80% = .8)

Gear Ratio = RPM / Head Speed

Pinion = Main Gear Teeth (MGT) / Gear Ratio (GR)
