12z and rudder dual rate question

[medflight]

I'm trying to set-up dual rates on my rudder. I'm trying to set-up one at 100% and one at 85%. When I set the rate to 85% it slows the rudder travel speed down but travel distance. I thought a lower rate was a lesser amount of travel. Can someone set me straight?
Thanks

If your using a GY gyro. The travel of the tail servo is set by the gyro.
The rates for the rudder channel just control the piro rate of the tail.

You will not see a difference in travel on the bench between the two rates. Unless you have one set to like 0 and the other to a 100.

The gyro controls the travel.

It seems I have the wrong idea of what is happening. The piro rate is what I'm trying to set. I want to have two different piro rates. I thought the piro rate was determined by the amount of travel in the tail blades; the more pitch in the tail blades, the faster the piro rate. I set dr rate 1 to 100% and dr rate 2 to 85% and expected to see less travel with the lower rate. When I lowered rated 2 to 40% all I noticed was slower travel.

Hi there.
It is like DavidH says; the ATV on the Rudder channels sets the rotational/pirouette speed of your heli. So if you want the tail to pirouette slower, decerase the ATV value or use DualRate on the Rudder-channel.

The actual travel of the tailblades are 100% controlled from the gyro, and if you need less travel (because binding or other mechanical setup) you have to decrease the Limit settings on the gyro.

Good luck.

Hirobofly,
I guess I had the wrong idea of how it worked. I thought a low rate on the tail would limit the amount of travel, in turn slowing the piro rate. I've used the atv's to slow the piro rate but that isn't what I wanted this time because I'm learning piro flips and still want a high rate at other times.

I've set the rudder up with dual rates. Just waiting on a little good weather to try it.

Thanks,
