I just moved my Pix from a y6 to a tricopter on the latest 3.3 release.
Yaw on the y6 was snappy, and control input was stellar- my throttle response felt instantaneous.
Input is SBUS on RC port on a FrSky x8r from an X9D Plus TX.
Moving to the tricopter, and I first noticed that the yaw was sluggish, and I know my servo can handle the props I am spinning- it simply isn't moving fast enough, or anywhere near the specified capability of the servo.
The throttle as well is incredibly slow, close to 1 second delay, probably in the 6-800ms range.
The whole thing seems terribly sluggish and unresponsive, and this is following an autotune.
I'm sure there's a way to tune the servo, it's my first tri on pixhawk and I simply haven't found the setting yet- help here would be cool. But the throttle and other control delay caused a crash today, and I haven't had one of those in a year!
