40" EPP wing ready to maiden

AUW 615 grams. About 400 sq inches area. 1800 kv motor, 40amp ESC, 2200 3s lipo, Radio is inside wing. Just don't have camera anymore for maiden so will have to get someone to video or attach my camera to my tx somehow.

First flight didn't go well as too tail heavy. Same story with first one I built as it has low sweep and needs forward cg - almost as much as staightwing tailless plane.
I will add couple ounces and it should be fine. This size wing carries more weight easily and doesnt effect flight time much. I expect to hit 20 minute flights with this battery as my last wing of this configuration hit 18 minutes on an 1800mah lipo..
The truth is in the testing I guess.
