RE: Another Fine Day With FEJ
I have used plastic arms on full flying stabs. Back in the day we didn't have metal arms.
I had an AD F16 with full flying stabs. It was perfect with 8411 and plastic arms. No flutter. I even used a big arm and last hole!
My 2 BVM F100 used plastic arms and 8411. Linkage on last hole no flutter either.
Designed correctly it works fine.
