RE: failsafe: how to make your 3d plane land itself
funny thing happened to me. i was flying my 3d hawk (35 dollar hobbyking foamie) and was testing the range on my 7 dollar chinese spektrum receiver. it never went to failsafe (which i did not have programmed like above) but i pointed her down and when i pulled up the plane pulled up but... the battery didnt. lol. the battery ripped off and disconnected. but i had already sent the "pull up" signal to the plane. it landed itself softly in the cement. WIN.
