    RE: Skymaster Ultra Dragon

    Fin/Rudder needs to be larger....taller (big canopy will upset airflow) and more cord to overcome fuselage nose area for good tracking...

    RE: Skymaster Ultra Dragon

    Anton,

    Live hinges for flaps would be nice.

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

    RE: Skymaster Ultra Dragon

    Anton. . .

    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.

    RE: Skymaster Ultra Dragon

    Anton,

    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,

    RE: Skymaster Ultra Dragon

    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, :-)

    RE: Skymaster Ultra Dragon

    I think you can increase the verticaly size of the air intlet to able to mount very big engine like P200.
    I don't know if I have explain it clearly.

    RE: Skymaster Ultra Dragon

    I think the whole concept is great. A larger Dragon will be nice. the cad drawings you posted look good to me.....maybe a little more cord on the fin and rudder for looks and added yaw stability

    RE: Skymaster Ultra Dragon

    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.

    RE: Skymaster Ultra Dragon

    Anton, if you want to do something special, you have to hit the Ultra Flash!
    The only real goal is. Faster, more durable, and cheaper!
    If you can not do this, forget it!

    Good job but why not other scale plane like a Alphajet for bee turbine or Rabbit? Maybe a small F9F?

    RE: Skymaster Ultra Dragon

    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!
