Ooooo real pity, I'm sorry you lost that airframe it was so beautiful. I see you saved the tail though
.
Yes weight is an issue on this airplane as it is with the struts - Aviation Design has no solution for the retracts so far. Hope they will soon. On the weight issue I've a P200RX on the airplane which is ok at top speed but not real push when the stick is below 50%. I was thinking for the new P300PRO but then it's a trade off - the fuel tank would be small and then if install something additional then I'd add around 2kg more of equipment and fuel.
Anyway I'll be following closely your thread.
