hi, when i set the total gain to 2 position switch, the swash plate move abit when i toggle between the switch. anyone encounter these?

and also when i give fast pitch pump, the rudder will also move bit by bit.

is this suppose to be?

With different total gain, the amount of swash movement is different. It is perfectly normal.

For the tail, which side does it turn? Have you tried increase tail "I" value?

the tail slider move to the left. is that a function of tail compensation?

isnt it dangerous if i toggle the total gain in flight when the swash move? it seem like giving slight aileron input.

Different heli designs have different effect on tail slider direction. Please tell us which direction the heli nose turns on pitch pump.

On bench test, the gyro does not sense the "free" move of the heli as it is in the air. So the gyro effects on the swash is different than in the air. When you flip the switch on the bench, the swash moves either aileron or elevator due to total gain change on the gyro effects.

While in the air, as the manual suggests, hover with 60% and then switch to 100%. If heli shakes, change it back to 60% and land it safely. Then readjust gain parameters.

In a nut shell, it is safe to switch in flight.
