I need some help in choosing the right planetary gear box for a Kontronik 480-33 motor. The matching Kontrinik gearbox for this motor came apart after just a few flights and Kontronik wont stand behind the product. I believe it's a 5.2:1 and I'm wondering if there is another manufacturer that makes one that will bolt up to the Kontronik motor ?
Any info on where I could find a replacement gear box would be appreciated

Thanks,
paul

You will probably get more help on the electric forum.

It needs more oil in the fuel, too much nitro! Or maybe a new glowplug. Yea, that is the problem, you need to replace the glowplug.
