I have a P3 STD & have not flown in a couple years ( ya I know ) Today I started her up ,with full battery charge & it flew fine , I guess , it was windy & she would move around a bit when no input at hover , what I did notice was when landing , at first it was two motors or props were slower then the other two , then one seemed to pick up & idle like the others & only one was on the slow side . Now because this has been sitting on top of my Safe , could the motor just need cleaning with some electronic cleaner or oiled ? Heck , maybe the three were running too fast , I don't remember , my bad for not keeping my experience up . Thanks in advance .
