Unequal pitch and roll
I just finished a rebuild of my Trex 500 with a ZYX FBL controller. I was checking the cyclic deflection, and am getting 8* of pitch if I pull the cyclic down or to the left. But I only get about 6* of pitch if I push the cyclic up or to the right.
The swash is level with 0* pitch at midstick. DR are all set to 100%. Went thru the full FBL setup before checking the pitch. Anybody have any ideas of what to check? It's got to be something simple that I've overlooked.

this is almost always caused by mechanical setup problems. In particular, servo arms not perfectly 90° to the swash rods at 0° collective pitch.

Went back thru the full setup process, and found that my swash wasn't exactly level. So much for the Mk. I eyeball - always use a swash leveler!
Thanks for the help.
