need some opinions on brass hinges with steel pins. I am building a 144 inch wing span super cub. The wings and flaps will have a total of 10 frise type hinges. the hinges will be made from sheet brass and 1/4 inch square tubing with steel hinge pins. will these cause any radio interferance?. your opinions will be appreciated.Thank You.

Use fiberglass printed circuit board for the hinge bodies. Stainless hardware. Seen a thread on these either here or on RCGroups.com.

In a word, no.

Your hinges should be fitted up with no slop, so there should not be any metal-to-metal RFI generated. A bit of lube wouldn't hurt, either.

I'm covering my 1/3 scale L-4 now, and it has the Frise ailerons but no flaps. Same hinge design, I think.

Nice try, no cigar.

I have three antennas on my mobile radios (ham) - they're all stainless. The operative part of the term is stainless _steel_.

OTOH the stainless pins certainly should have excellent _wear_ properties.
