It's cooling vents for the ESC and motor. I still have to figure out how I am going to fasten the hatch down, needs to be more room in the battery box for battery removal and replacement. Might have to do some shifting around in there, it's a bit of a tetris game to get the battery in there on CG. And I still have to fasten the Rx in. Other then that it should be good to go
Predictions on maiden... Sketch factor at about 20%, which is a lot better then the Alpha. Maiden always has the unforeseen variables. the one thing I don't want to happen is a LOS, I am pretty confident that if I have an ESC cut out that it will glide to safety, I really don't want to bang up that pretty nose before paint. It should be a little lighter then V1 and V2 of the 22 given I removed a good amount of paper from it, has a larger slot, and I only went with single thickness Vstabs. It should be way more maneuverable then the other versions as well due to the elevon style. Over all I am pretty happy with it
