| F21 Predator is an EPP combat slope sailplane.
The fuselage and wing are made of harden EPP foam while the tail is made of coroplast.
Balsa sheet enforcement is needed in order to straighten the fuselage. The plane is good
looking on flight and the penetration speed is about average. It is highly maneuverable
but the response is a little bit slow. |
