Joe Yap's Easel, a 28inch Electric flying wing inspired by the weasel that he created for indoor pylon racing. He won the recent ISAC indoor pylon race with it. Hotwired cut from white EPS foam, setup was 2000kv mini outrunner motor, 5x3 inch prop, 2s 350mah, 2x 5g servo.
I had a chance to try it out today, very agile, maneuverable in tight spaces, super fun.
This is how he trains for the pylon race.
