    I have thinking the same, but using a helmet-vario!
    But what cind of sailplane and motor, bec, propp and
    how many lipo cell?
    It looks like a very easy sailplane for handlaunch :-)
  • It's a competition glider, 3.2m wingspan:

    Prop is 18x9, 3S 2500mAh used in this flight using kontronik 500 and 55A Kontronik BEC. I can use motor for ~2mins 30s, then battery empty :) That's why I use vario!

    Helmet vario is more expensive and more heavy :)

    Really Raphael? Only 2.5 mins runtime on a battery of that size. I can get about 7 mins out of my stock EasyStar NiMh packs. With gliding I usually get at least 20 mins of flying per pack. (I have only 2 of them). Will update to LiPolys some day. Thanks for the cool vid. - Rob
  • You can do the math ... 2500mAh, the motor pulls about 45A:

    2.5 / 45 = 0.0555 * 60 = 3.3min

    Keep in mind I still need to power servos for the time I'm in the air also ;)
