I go away for a few days and this happens?????????

I don't know nothing about nothing.

This is what I know. Profile & fuse 3D planes with thick airfoil wings, with wing tip, do not perform in the same manner. Greatly improved KE, harrier, roll speed and just tossed around allot better.

My thinking, remeber, I know nothing; the wing tips increased stabilty at speed, like for pattern or general sport flying. On landing, if you got it too slow it would TIP STALL. Up until only a few years ago, most pilots wanted a more stable plane. For 3D, I don't want stablity.

I was the first to suggest cutting off the tips when I had success with it on several planes. First plane I did it to was a ZN Line Madness.

Don't know why it works, just does.

Math don't lie, 3D does.
