Summary

I've been having fun with this little 3 channel RC P51 from DEERC. Flying with the nephews, I wanted better slow flight characteristics and less wing drop tendency. These fixed 15 degree flaps did exactly what I wanted.

My printer has a .6 nozzle on it so I made the flap .6 in thickness.

For installation, I put blue painter's tape on the wing to protect it and then used carpet tape to attach the flap to the painters tape.
