38" Superfly-Megafly clone
This is a close SF copy built using 6mm depron. I had been experimenting with a KFm4 airfoil with the top step at 50% and the bottom step at 40%..
It has surpassed all my expectations, it will fly hands off upright and inverted for a considerable distance. It has a wide speed range and is very manouverable.
The double KF step has produced a very strong and stiff wing..With its tape covering it will take a lot of abuse
