I didn't catch Barracuda's response but he is correct. The fins have a lot to do with how the heli responds
backwards. They are made mainly to guide the heli while flying forward. Solid fins will weather vane more
than 3D fins. 3D fins are only the basic outline of a fin and really do not do much. The verticle fin will
protect the tail rotor a little. I have broken horizontal fins and thrown then away and never replaced them.
I wouldn't recommend that with the verticle fin because of how it protects the tail rotor.


When you fly tail in, are you flying facing the wind? That will make flying backward a lot easier.
