This concerns anew,never crashed Amain Trex 450 super combo. ESC is RCE BL45P. Batteries Venom 2200. Transmitter Spectrum DX6i. Flew fine for 4 flights then I realized I had full collective to maintain weak hover. Batter ystill at 80%, changed to full battery but still required full throttle to maintain weak. Pitch and power curves set per Trex manual and confirmed with digital pitch gauge. Transmitter monitor indicates full throttle movement. Would it help to reset Beastx or does this sound like a REC or motor problem. Hope these are enough clues for you detectives. Thanks in advance.... Rob
