Hello Pull Up Now
When I first read this thread, I was very concerned to put a Bee 80 in this airframe because I fly at 7000' altitude, we lost here near to 30% of the thrust (and the lift)
It turns out that the power was more than enough and it fly’s for 8 minutes with plenty fuel to land, and feels like a sport jet
Only modifications I made were to the fuel tank, I made a new stopper hole a little lower than the center, so the clunk could travel from the bottom of the tank to near the top
