calculating gear ratio
OK, I'm going at this in another direction. My gearbox on my Yak 55 has the bearing support broken. I don't know what size to buy. I've counted the teeth on each gear. The pinion has 11 and the spur has 51. It mounts on a square balsa stick 3/8". What is the ratio? And where can I get one? Thanks

RE: calculating gear ratio
Back to school:
How many times will the pinion gear turn in relation to the main gear. 13 into 51=3.9 to 1? Solution, buy a brushless with adequate power to fly without the complications of gear systems. May be cheaper in the long run aftr buying gear systems and airplanes when the gears fail. It sure would be a much better flyer. Gear systems in my view are a crutch for adequate design. To each his own! Sorry, cound not resist the jab.
