I doubt you will ever find one of these ....but the Worst engine I ever owned..Flat out!
Was the OS .35FP!

I swear I have a patch of grey hair from that engine!

I bought it at a time when I had just gotten married, and things were LEAN for us!

If I had the money I would have thrown that thing in the lake and bought something else!

It drove me out of the hobby...as I couldn't afford to repair/replace the planes it ATE!

When I got back into flying, a year ago..I found all my stuff as I left it in my flight box.....

And there, sitting on the bottom was that Damn OS .35!!!

Can you guess where it "Rests" now??
