Thank you for your responses. They are much appreciated. I knocked up a rough CG stand just in case my fat fingers were causing any bias. I have everything in place as it would be in flight and 3s 2200ma lipo battery sitting hard up against the back of the firewall. I sharpened the tip of the dowels to a 1 mm chisel point and the plane rocks freely without hesitation. I had to reverse the undercarriage to fit the stand in. I think it looks fairly well balanced. Looking down the plane the main wing and evelator are in good alignment. I am thinking more along the lines of too much increase in thrust for very little stick movement. I think anyone would have trouble driving a mini minor if it was powered by a super charged V8 with only 1 inch of total throttle movement. While I am waiting for the new props to come I will knock up a thrust meter and adjust the throttle curve on the transmitter to have a linear run up and cap the thrust between 700 and 1000g. I found this feature while I was doing my repairs. View attachment 145420 View attachment 145420 View attachment 145421 Does anyone have a CG point for a heavy cub that worked for them? I could also set up the ailerons and run them in flaperon mode with a little reflex if that might help. I did plan on going to 4 channel eventually.
