Flying wing rear mounted motors, whats best or possible
HI ALL, I have just built two flying wings, I intend to fit the motors at the back with pusher props, but I have a dilema, they are both foamies, built from the blue builders foam, its all I can get here in spain, no model shops for miles, its a while since ive flown and back then it was all engines that needed a glow plug and a fuel tank, I have fitted pylon style foam mounts on each of the flying wings to get the prop up clear of the ground, but I am wondering if the high thrust line will affect the flight and control, any advice would be much appreciated,before I get to the stage of mounting the motors, im new to electric systems and to pusher motors, but not to flying, thanks for your time, alan.
A hi thrust line on a pusher flying wing is going to be a real challenge to control.
Your going to get wild pitch changes with throttle on/off unless you can angle the motor WAY down so the thrust line goes through the CG of the model. Thats going to make the prop very in-efficient because your thrust line will be off from your flight path to a very large degree.
Thats why no one does flying wings with raised props - its almost impossible to make work well at all
hi all, many thanks for all your comments, brilliant, its a good job i thought to ask before i finished the build, looks like ive got some foamcutting to do, looks like i also have some challenging flights ahead, muchas gracias to all from alan in spain.
