Live hinges for flaps would be nice.

And can I get some trade in credit for my now compact dragon for the bigger version?

I love the design and the fact you are going to make this already great jet even better. I agree with Dave re; the vertical fin/rudder. From the CAD, it looks like both can be enlarged. . .BUT keep the sweep for stability. My suggestion would be to make the stabilizer/elevator and vertical fin/rudder exactly the same size. Benefit would be one mold for production as well as part exchange availability. There are aircraft manufacturers today who use this very concept. Another benefit would be aerodynamic balance due to exact airfoils of both.

I look forward to getting my hands on one of these. Keep us informed of your progress.

Best regards,
Eric

If you make the fin/rudder too tall,you will get excessive coupling during Knife edge flight. This can be mixed out,but is something you should at least consider.Good luck,

Erik

Status: offline 		The trailing edges of the flying surfaces on most jets are to sharp, ( come down to a point) if these were kept thicker ,this also increases straight line stability. The fin / rudder trailing edge is one of the most important to do this it stops fish tailing.
Shape looks great, better than some to do the F3s job, :-)

I don't know if I have explain it clearly.

Status: offline 		Normally preparations work to assemble wing to fuselage before each flight is annoying..

So I will design a three-piece-wing.The mid wing is permanently fixed to fuselage.It is only 95CM(37.4") long and can easily sit inside the car.

Just assemble two small wings and two wires to fuselage before every flight.No need to retract gear and insert airlines.

The only real goal is. Faster, more durable, and cheaper!
If you can not do this, forget it!

Status: online 		Would be awesome to have wing tips like the Ultra Flash family. I guess they are functionally reducing wingtip drag, making the plane more slippery. If not, they look cool as $**t.
P.S. Standard Dragon version 3, same tips IMO.. GREAT JOB on the Ultra Dragon!
