Yes, he keeps the nose down too long, but thats maybe typical a Goldberg Cub, it may be difficult to land it other ways. Maybe Im wrong.
I just got my cub ready to fly, after doing different things. I balanced the cub, and I experienced that it wasmuchnose heavy. I had to move a bit heavy 1700 NiCd batteripack from beneath the tank to the wall in the back of the cockpit. This measurements was done with the CG point at approximately 4 inches behind the leading edge, its equal with 36,5% behind the L.E., a bit much, but thats what stands here:

I hope it will fly better, Im gonna try the plane in the easter, if the weather allows it
