Hello,
Her is the spec of my next jet, what do you think about it (weight, length, wingspan ratio, etc.):
Length: 48 inches
Wingspan: 46 inches
Weight: 12 lbs (estimated)
Wing area: 550 square inches (approx)
Engine: JetCentral Rabbit (19 lbs)
Tank: 50oz
It’s a design base on the F22, it’s not a scale to minimize the complexity and the weight… It’s will be equipped with flap, retract and air brake…
Thanks for your comments.

That's 50 oz/sq ft. on a 46" wing span. Assuming that's the dry weight, that's about 15 lbs wet which is 63 oz/sq ft. - even worse. I would think that this jet is going to be a real handful. I would not get the wing loading up that high on that small a wing if I could help it - especially since it appears its going to be a self-design. In addition, as stated, the Rabbit is too much engine for that plane and I'd be surprised if you can actually bring it in a 12 lbs (dry). I would not want to risk a brand-new Rabbit test flying this airplane...
Yes, there are lots of jets out there that have a higher wing loading, but generally they are much bigger and bigger flys better at heavier weights (Reynolds numbers).
