Me and a friend are trying to fly in formation with our schraut5 inspired scratch built Kline–Fogleman airforil wings.
The plane chasing is flown FPV by myself and uses a KFm-2 airfoil. The other plane uses KFm-4 airfoil and is flown line of sight.
If you are interested in building a plane like this you can find the instructions here:
