Hello folks,

May I know if there is still place where I can buy the older version helical main gear? I noticed that the teeth started to show some signs, not sure it they were like this before or just due to the recent relatively short flights??!!

otherwise, not sure if the later straight gears will be a direct replacement? but then again, i have to change the pinion from clutch, main gear and the tail transmission gear...3 pieces...

anyone can make me a helical gear?

Cheers

Lawrence
