Field sightings 12 Apr 2014

Spencer built and flown a foam mini cub on rudder, elevator and throttle.
The remarkable aspect is that the wing has no dihedral (practically), although he insists it has because he bent the wing upwards.
I wouldn't have tried to fly a high wing cabin monoplane without dihedral but he did it.

The other interesting aspect of his model, is the carved airfoil wing.
He said he used a chopper to pare down to approximate airfoil before sanding to final profile. His wing was made up of an upper and a lower foam blanks.

Model is very light, about 100 grams, is about 22" span.

Obviously rolls are out, and his 19g motor cannot do pull outs, inverted looks a challenge. It flies best when wind is only slight.

I think I could try his wing construction for my Blackburn Monoplane (original flat wing without ailerons, or with ailerons (logic being that given time and opportunity, the original Monoplane might subsequently be fitted with ailerons).

And on this day, I pass the soldering tip to Andy and a P-36 to Wong (foam/ply, ca 29" with HobbyKing Donkey motor and 7"x4" prop).
