Yesterday I did a test, I flew my P2V up until I lost connection with the RC, and a RTH was initiated. the unit came home and at about 20M away I switch S1 to from GPS (top) to ATTI (center) then back to top position and regained control. continued my flight, until the battery was about 25%, the unit was only about 10ft off the ground and about 20ft away and just let it hoover. I was expecting the RTh to kick in on low battery but it did not, instead I could hear the rotors getting weak and tit came to the ground pretty fast and the rotors turned off. I got no RTH sign on my iphone. this kinds worrys me, if I interrupt a RTH, then lose control the RTH will not kick in again. can anyone confirm?
