I just got a blade CX for Christmas and got it flying just today. Inner shaft gear (lower gear) is getting it's teeth all ground up! Now it wont fly. I just upgraded the inner shaft to aluminum and was wondering if I can do the same with gears. If not can a buy JUST the gear without the shaft. Please help me solve my problem

Thanks in advance!!!!!

you can buy lower gear at helidirect.com

once you replace the gear, check the gear mesh with a piece of paper between the motor pinion and the gear. a mesh that is too tight might tear up the gear.
