My Hyper went south as a bearing chipped and went up through the engine. I went out and bought another Hyper and am waiting for warm weather to break it in.
Question is I have the old motor here and found it needs a rear bearing ,cylinder liner, piston and ring from the looks of it. Can i use the old con rod ,piston pin and or retaining pins?
Is this thing worth rebuilding to have as a spare or is this motor a throw away piece at this point?
Thanks

Setup is everything, All my heli's can fly far better than I can pilot them

It's most definately worth rebuiling. You're looking at less than $100 in parts.

Hell... I can fix that.
Uh oh..
Nope.
It's ***ked!!!

Yes you can. I just rebuilt my YS 50 with a new piston/ring/liner and reused the con rod, wring pin, and retaining clips with no problems.

I would replace both bearings and the piston/ring/liner. You would essentially have a new motor once it's all put back together.

Yes, then you will have a spare, just swap out when the other one goes south, then repeat. Those wrist pin retainers have a way of disappearing, so be careful when taking them out.
