The first flight of the powered 25" Depron Frog Wren with the oversize single fin and rudder. This ensured more than adequate control which the original small twin fins did not have.
The over powerful rudder coupled with too strong a wind ensured the flight was not easy .
The video is edited as much of the time it was too far away for the camera to see but it does show a rather untidy loop and a completely unintentional snap roll!
It gradual stages it will hopefully be returned to its original twin fin condition.
