your head speed is TOOO LOW !!!

my trex just whipps around , !! it must be your head speed , or you have some crook lipo batterys , just by adding flight power lipo's to my bird i had to back off my throttle curve to stay under 3000 head speed , im down at around 50 % throttle to hover and 80% throttle to fly aggressive


the batts can make that much of a difference
