following is a 2 part video on installing a LABEL UP (Detrum
GY48V) gyro onto the Rudder (Yaw) axis of a Cub (Piper L4).
The gyro was
purchased from HobbyPartz.
Although the videos show how to set up in both Heading Hold and Rate
mode, I recommend you try it first in Rate mode. Most of my
Rudder Gyros I operate at about 70-80% gain in Rate mode. With Heading
Hold, I needed to turn down the travel adjust or dual rates on the
Rudder channel to make it controllable while in Headin Hold mode. I do
not like the idea of taking off and NOT touching the rudder stick.
Being that I take off from grass, the clumpy bumpy runway
not treat even a heading hold gyro kindly. A smooth blacktop
a straight firm tailwheel will be much better. With Rate
I do need to make minor stick corrections, everything is easier to
control. With Heading Hold mode, I found that I needed to do
tweeking to the dual rates when using HH mode on take off. Thus I
recommend to start with Rate mode.
