I was wondering if anyone has installed a brushless motor system in a 22d or 22A? I have a helidirect hdx300 brushless system I want to install in my 22d, I was also wondering what size or how many teeth pinion do I need and were can I get the pinions. The pinions would need to be .4 module. I'll be using a 11.1 v lipo with the setup. The motor shaft is 2.3 mm
