Default 120SR Flight adjustments


Having a ball with my 120SR. I'm where I can put it where I want it a hold a hover until I'm bored. However, I have noticed that when in hover, cafefully adding rudder either way, I get a slight forward or reverse response in addition to a greater yaw response. Is this normal? I'm using a LP5DSM transmiter. I suppose I could trim it out with a programable trans, but can I trim the heli someway to remove it?

Thanks, Bill

Well, just a guess here, but when a heli is in a stable hover, it's not really straight and level
due to the side thrust of the tail rotor. You are really leaning (as seen from behind) a bit to
the right and this is perfectly normal. However, if you then add some tail rotor input in either
direction, you aren't really just inputting rotation, it is slightly skewed up or down depending
on the input. Just my 2 cents worth.
