If it balances and you have enough power on the front of it, it should fly.

Seriously though, I dont see anything that would prevent it from flying. It looks a lot like some other designs that have been posted up. It might be more stable if you extend the tail some. Other than that I dont see anything wrong with it. just keep it close due to the small size of it.

Have you ever flow before? If not, I would highly recommend using a proven plan for the first one, then build this one to experiment.

essadiq,

I'm comparing your specs against my specs...It looks interesting. One thing that sticks out in the angle of incidence of the wing looks like it could cause you some problems. I don't think you need any angle at all with a profile model such as this. If you are worried about lift, you might want to consider a KFwing instead. I like the side view of the fusalage. Check out how Gene Bond used a KF wing on his EPP piper's wing. It both gave the wing strength, added in lift and also allowed the profile fusalage to fit into a slot for more strength.

What material are you going to build it out of...EPP, Depron. What do you think it's weight will come out to be with and without motor, battery and esc/receiver.

Regards,

Hankg
