I had/have flaps on mine and after flying the plane didn't think they were needed. I have TT Pro 46s and at idle it floats in real nice. I'm doing a little reconstruction on mine and am going to eliminate the flaps. I did like and use the same setup as "mucksmear" for my flaps but didn't have enough deflection to make them effective.

My wing is repairable but the fuse is a comple rebuild. I left the "per Pica plans" gear setup that came with the kit and was having problems with prop clearance. I'm modifying the gear as shown in the Mk II version so I won't be challenged in that respect.

This being your third "Duelly" are you planning any other mods that the flap setup?
