Is the sig control horn with nylon horn useable for a 35 size sport plane? Is there a way to insure that the horn wont spin on the wire. Thanks John

I would not use one.

I have used them in the past, but not on anything bigger than a .35 size plane. Especially in cold weather like we have now. The nylon gets very brittle with the cold and also with aging it will get brittle. Save your self some grief and don't use it. H^^

NO, NO, NO a thousand times NO!
I lost my Nobler on one of those that broke. O.S. .35 S (so much for that crap!)

Bought a Sig flap horn to try on a homebuilt a while ago. When I opened the pkg., I tested it and it was way too flexible. I also could feel play in the plastic horn. No matter how you feel about your aircraft, don't use it. Your ships have value added by your labor on them. Don't use something that may cause a failure. All the ARFs that I have put together (C/L and R/C), the hardware bag gets the "round file"...
The anything that resembles a Sig style horn would too.

Put them in the garbage, I used one in a Nobler flap and while I was sanding the horn broke, do you know what a job it is to change a flap horn in a finished plane. n1

Neal I do know what a pain it is. This plane was almost ready to recover. I removed elevators cut open bottom of fuse and removed that sig horn. Replaced with all steel version. Now I need to open top of fuse to check what I used for flaps.

I lost a Sig Chipmunk on the L-pad a few years ago, when the nylon horns just plain bent from their positions. This allowed much less control throws than what I needed. Use a metal horn and save your plane. (Throw the nylon things away.)
