Ok while waiting for the backorder on the new airplane I decided to do a quick fix on the broken one and re-install the magnum 40 engine. The repair was quick but solid and the monokaot is not the same but it was just for a test flight. I took the airplane to the airstrip and left at a 20-30 deg. climb out. No stall and no unusuall behavior , although underpowered it climbed out at a steady speed and continued onward for 4 good flights. I just dont understand why it doesnt roll with the magnum 40 but with the saito 72 it does. I did manage to get some better video this time and it did fly quite well but I still had very little vertical but after 4 flights it is still acting normal on takeoff. Maybe a little smaller 4 stroke in the new one when it arrives?
