RE: Curare build
If you can, then get a hold of the RCM&E plan (the web address is in the forum somewhere) all wood, reasonably accurate formers and shows the original (1975) Curare with the simple (Sicroly) type flap. Built to the plan with a HP Gold cup .60, mech. retracts with two retract servos and Solarfilm finish it flys at 6.75 lb. I can supply the original magazine article that goes with it too.
