40" Wing - getting longer flights now

Flew at 5:00am with slight breeze - 1800mah 3s lipo and got 15.5 minute flight on my 40" scratchbuilt epp wing. Guess that is my limit as my arm is sore from holding the radio and just tired of looking up that long but happy - longest flight to date.

From 12 sheets of epp foam I now have a fast wing, a putzing about aerobatic delta wing, a 40" wing, a P51, a couple of "normal flying" 30 inch wings, a forward swept wing, a plank wing, and a few failure wings.

Sitting at about 44 hours total air time now for about two years flying. 6 more hours and I could qualify for my private pilot certificate.
