100KM

Twinstar fpv lost and found by girls.

Ever wondered what happens to your lost drone or plane while you are searching for it ?

Had to make an emergency landing with my fpv twinstar because it lost a propeller.  While I was searching for it, 2 girls found the plane, and their conversation was recorded by the still operational HD camera.  I was quite amazed by their technical insight and conclusions !

Enjoy !

    No APM in the plane, my APM is in my hexacopter.

    I'm fully to blame for the crashlanding, not ardupilot :-)

    My twinstar is also rather pimped, with stronger motors and bigger props.  On more then half throttle, the controlsurfaces won't be able to override the torque of 1 motor.

  • That's a pretty neat test, but note that shutting off that motor would actually make it more controllable, I think. Now the single motor operating is closer to the center of drag.

    U4, were you flying with an APM, or straight control?  Looks to me like simple FPV flying?  

  • Ah de mannen van Diest hebben ook APM :-)

  • Awesome video. Youre lucky it wasnt found by boys.

  • the "old bat" part was rather un-called for. It should have been thanks for not killing it with her shovel.

    Propellor didn't break I think, it just unscrewed, probably by the long descend with high headwind.  I guess that made the prop drive the motor as a generator, slowly unscrewing it.  Prop and spinner nut were missing.  I haven't noticed any other damage so far.

    Yes, the twinstar can fly on 1 motor...  if you realise that you only have 1 motor, don't give too much throttle and apply the right amout of aileron and rudder to countersteer.

    I have flown on 1 motor with it before.  But not in 4 beaufort wind and not fpv.  Furthermore it has been years since I lost a prop on the twinstar and I didn't hear the "klak" of the prop comming off.  So I thought something else was wrong.

    I did notice that my amp draw was much lower then what I was used to for a certain throttle setting, but still I didn't make the  link to a lost prop.  If I had realised a prop had come off, I probably could have gotten it home.

    My twinstar with AXI 20-22Ls can fly single engine. I doubt if it would fly particularly well with a load though.

  • Huh, interesting.  So the Twinstar can't fly on 1 engine?  Well, there goes that plan that I had.  I figured it would make a better airplane because it could still fly if you lost one motor.

    So why did the propeller break?

    Cool man, really got to hand it to the girls though for not taking it with them?
