Again. the OS remote nva from the LA series engines bolts right on the McCoy .35.

Can't fit both pictures on the same post. It will take some minor trimming of the bracket and lots of plastic washers to install it on a Fox .35.

How well does it run?   Have you tried it in flight yet?  Very interesting.  Those McCoy needle valves are hard to find.

Thanks for the tip Perry.  I'm getting ready to put a MC35RedHead on a ringmaster.

I've had several of the metal needle valve plates break from fatigue fractures.  A piece of 1/16in. nylon sheet or even a cut down control horn does the same job and only sometimes breaks in a crash.
