401 on a blade 400 problems

[flipnap]

Hey all, i just had my LHS dude install a 401 gyro for me on my blade 400.. everything else is stock.. he took it out back and flew it to make sure all was well and it looked fine to me.. but tonight i took it up and its doing this weird thing.. when i chirp the rudder a tad, the tail bounces back and forth a few quick times before it settles.. it doesnt wag when its just hovering but only when i input rudder.. it doesnt just snap into place.. its rubbery if you know what i mean.. is this some incompatibility with the stock tail servo or is there a setting i can adjust.. thanks yall..

(edit) sorry, forget to give you some numbers.. the gain on the TX is set to 60%
the numbers on the 401 pots are:
delay:75
limit:100

Suggest adjusting the delay, and gain, one at a time in both directions to see what might improve the response. It could need more, or less of either adjustment.

A delay of 75% is bit high unless the servo is a little slow. Double check that it's not really on zero (the screw driver slot can face zero and 75). The gain of 60 on the TX is hard to interpret without knowing how that radio is scaled and the end points/atv settings for the channel. Also check that the flex and linkage slop is minimal.

Best of luck,
