I built the Kyosho Cub about three years ago and it sat on the shelf in basement . Power is an OS 46. Yesterday I tried to fly it off some fairly tall grass in no wind conditions. I horsed it off the ground several times with a too low flying speed. It dropped back to the ground each itme and cart wheeled, etc. Finally I let it fly off and got it up about 30 feet and it apparently stalled and went in nose down. Everyone watching was amazed. Just nosed over from a wings level, nose level attitude. I'm not an expert pilot, but have had a half dozen various kits and ARFs that have flown OK. This seems unusual. Anybody else have similar problems with this plane?

Didn't know what wing incidence was supposed to be, but when checked, it was positive 2 degr. from horiz. stab. I set it to zero and tried to fly it. Same results as above. Everything looks good. Next step is to put wing on Hobbico 60 Trainer and see how it flies. Can't think of anything else. Comments welcome

Check out the cg. I had one with a 46 and it flew just fine but it would snap on landings. I put a 4 stroke in just because a cub needs a 4 stroke()and it stopped. I think that the cg in the manual is wrong. balance it a little nose heavy. if it already is, add more to the nose. Ine of my best flying planes I have.
