RE: Suitcase Shrike
Walbanger,
There is nothing wrong with a properly done Z bend. I suspect there is too much slop somewhere and you need to get rid of it. It could be in the servo or linkage or maybe the torque rod in the aileron itself is loose. I over sanded the ailerons on my Shrike and had flutter only at top end speed in a dive. I finally covered the gap with a 1/64 ply strip and the flutter is gone.
