Most Excellent, Rowdog! I applaud you! Gives me hope, some day I may take mine down from the ceiling and fly it. Looks like it flys just like my Z. I have a magnum 120 four stroke in mine, and it balanced like yours. I just had problems with a too high idle, and sort of moved on to other models. It sure looks good hanging, I have two smaller non flying Gee Bees on display with it. Duane
