Flexwing-Finch

26.9k Sunnyskies  8.1 years ago

An experiment in using flexible wings in the place of conventional control surfaces. The wings and stabilizers are twisted by a system of rotators, with controls like a normal plane. The turn rate isn't very great, but it can be increased with rudder input at the appropriate bank angle. The roll is very smooth, and is dampened by the speed of the rotators. Very nose heavy below 200 mph, so you will need some throttle to land safely. The plane isn't incredibly fast, but it does have a nice fade-to-tip paint job.

    @Liyicheng @Treadmill103 @Unreliablewaffle365 @MAHADI @ChiChiWerx @saturn28 Thanks!


    @Flightsonic These wings were about the largest I could manage. Any bigger, and they got too heavy and floppy, which made the plane difficult to control.

    Innovative experiment. Mentioning the speed thing, it would be great if we had some supersonic effects in SP, but, alas, straight wing and swept wing aircraft fly exactly the same way...

    Could use some larger wings, otherwise, great concept!
