OS .25 from eBay, looking for info
I just received this in the mail and wondering what to call it. It looks decent and moves freely. It was listed as an OS fp25 but there is no "FP" marking. Just Max OS .25. It has a small 702 muffler strapped on. Iron, ABC, Schnurle...?
Thanks,
Rusty

Re: OS .25 from eBay, looking for info
Hi, this is a .25 Max R/C.
No ball bearing, plain bushing,
not Shnuerle porting but piston (cast iron ) with baffle.
I bought mine in 1976...
Need a lot of castor oil (20 - 25 %)
Good engine,

Older muffler mounting strap. Muffler mounting is integrated in the casting on newer engines.
Based on Navion's comment, drop the muffler off and look in with a good light and see what the piston top looks like.

Thanks for the comments, I'll take a closer look. I have an NVA on the way for my other fp25, They probably have the same requirements in that department.
