Hi Troy,
Could you please tell me what the thread size for the output shaft on a YS50 ST heli engine?

Regards,
Syd.

I'm not sure will have to check on that one. I don't know much about the heli engines...tuning them is about the same and how they work...but specifics like this....I'll have to ask.

My guess is the 8mm x1 this is the thread size for all current YS engines on the 4 stroke side of the house.

Just talked to Richard Verano and all the YS engines currently in production....the Heli, and 4 strokes are all 8mm x 1

The older 2 stroke airplane engines were 8mm x 1.25
