40" finless epp wing

Finally got my 40" wing flying well. A pretty good glider at around 5 WCL. Got 12 minute flight in a little wind on 1800mah 3s lipo, 1800kv motor and 7*5 prop. Moves pretty fast full throttle and floats around on 30%. Want to try 2700kv motor next.
Boneyard #5. Laminated 9mm epp foam. Had to move motor forward and still has 2 ounces of weight in nose. Should just move up to 2200mah battery.
Shouldn't have made the weird prop cutouts though, should have rounded them. Put a fiber rod to tie back ends together.
