I have a new and a V good condition OS50H engine that have had the rings broken. They are the original 50 (not the modern hyper type) engines with the top mounted 'L' shaped ring.

Anybody perchance have any new rings for this engine in their spares box or know who might have some.

Joe

PS dont ask how the new one broke as its a 'sore' subject......

"L" shaped ring would be a "dykes" ring. That's going to be a hard one to find.

Edit, maybe not that hard...a search for dykes piston ring got this website:

http://stunthanger.com/smf/index.ph...=3109.msg135733

Don't know anything about this fellow, but seems to have all sorts of rings and can make them.

Engine Rings, custom made, source 2:

For all of us modelers who need piston rings and cannot find them, try contacting Frank Bowman. He manufactures repro and current piston rings for our modeling needs. He can make standard and Dykes type rings. If he doesn't have the ring you need in stock, you send the piston and cylinder and he will make it then. prices are $7.50 up to $9.50. His work is of the finest quality.

Happy landings, Zach

Frank can be reached at fbowman@acs-online.net or 1-505-327-0696 ( 6pm to 9pm mst. weekdays) and the following address:

Thanks for that.

I have a number of other engines that I nearly threw away that only needs rings. Good info and I will pass it on.

Rings
I've bought rings from Mr Bowman to rebuild a couple OS 28's for Crickets and they work well.

I found all the parts for my os 50, and 61 rf's at Tower hobbies. If you know the pn, type it in under search. They have a parts listing for the older engines, takes some digging to get to
