Zero
Hey, thanks! I had planned to glass the wings, since the concept of ironing Econocote over foam gives me gas.
Ouch on the retract thing ! Retracts in general seem to be my Achilles heel in warbirds. I'd think about re-vamping for a heavier set, but if I remember correctly, that would require changing the cutouts in the wings in a major way.
Appreciate the input from somebody with real experience.
