I have a thunder tiger e550 with beastx gyro that flys great except on fast forward flight the tail goes up and down. I'm not sure what to adjust to correct this and any thoughts would be appreciated.

if it doesn't fit, make it fit.

I don't know what to adjust on that FBL, but that is commonly called porpoising. I'd imagine a BeastX and porpoising search will get you started in the right direction.

Parameter C is pitch up compensation. You likely need to increase this value. I think red is default.

purple - very low
red flashing - low
red - medium
blue flashing - high
blue - very high

yes, red is default. It is set at red now. I'll bump it up to blue flashing and let you know. Thanks.

Hey buddy.

Cyclic gyro gain too high also maybe?
Like a tail rotor would, but it would wag left to right with the gain set too high, a too higher cyclic gain could induce a porpoising/nod but you'd see it in the elevator/aileron directions instead.
