Just finished looking at the two DVD's Windy sent me. Changes Windy made or reccomends are radius l/e,use cf tow on ball links and epoxy top and bottom nuts on bellcrank,motor offset 5/16",replace flaps with 1/4" 4lb. stock flat sheet/radiused edges, Rabe rudder (personal choice), tape all hinge lines. he is using RO/Jett RE .76/ 14x5 Rev-Up, 68',.018's. He says front lead out runs when l/o's to far back. If possible remove peice it rubs on (ARC). Need 1/2" longer gear when using 14" prop. Windy has got the weight down from 65oz. to 62oz., he now is using one of his CF spinners. Hope this helps, i am getting more DVD's as they become available. I will be happy to share them. Ron
SORRY meant to say elevators with 1/4" not flaps, and word is rub not runs on lead outs.
