Charles, "Misconceptions"? It should cost them alot. This is an ARF. The control surfaces should not need to be balanced if you follow their instructions to the letter. But there has still been a flutter problem. When I buy an ARF I am expecting to not have to be an experienced P-38 test pilot to fully grasp how to fly it without watching it fall from the sky after that dreaded buzzing noise. Where there's smoke, there's fire. How many other 1.2 size models DON'T have threads like this? Most of them!
