It is definitely going to want a lot of thrust with this much sweepback! It looks really cool man! Reminds me of the aurora. should fly I reckon! Nice big elevator throws, small aileron throws, maybe try chucking it over long grass with no kit in to find c of g. if not make a little one and throw it around a bit. ( my neighbours think Im mad cos Im always running up and down the street throwing some sort of chuckie around) LOL! I usually put some control surfaces on my chuckies so I can get them to roll to test roll stability to let me know If I need more - less dihedral or anhedral plus it helps you to guage how big your aileron throws need to be plus you can get a much better Idea of c of g if you can test the pitch sensitivity. Cant think of anything else which might help. Good luck!
