Hi,

My titan takes 1 sec to complete 1 pirow.
Is that normal?

How do I improve it?

Thanks

Go into your radio settings and increase the end point adjustments on the rudder servo. This didn't make much sense to me at first when I was new, but this is how it is with most helis, and gyros, at least with the Futaba 401. The ACTUAL servo end point adjustments are most likely on the gyro itself. Hopes this help, but I could be wrong. This how you do it with a DX7 and Futaba 401 gyro. Check your radio.

That's correct

The gyro has the mechanical end points so that it knows the total range and does not bind the servo

The TX rudder end points control the max value sent to the gyro
All Futaba heading hold gyros convert this value into a "piro degrees per second" request
So the bigger the TX Rudder end point, the faster she will piro
How much mechanical travel is required to achieve this piro rate is left to the gyro,
the gyro is sensing the yaw rate and increasing/decreasing the mechanical travel as required

Choose a piro rate that you are comfortable with
