Thanks, I used the middle setting they give you for the CG , maybe I should try another 1/2 inch forward to make it more nose heavy, my prop is a 12x5 ,I noticed how light the huge wing is and its like a kite when the wind hits it, when I come in with almost an empty tank on a windy day its tricky ,when you slow down the throttle it wants to rise up bloom, and then at the slightest throttle its staightens out forward but wants to take off upward again. my down thrust is good ,on a calmer day its much better, but what will make it better on a windy day?? I believe any tail weight would make it worse. any suggestions.
