I have checked work of GYRO by the bench test in the following setup.
Combined Orange RX 6ch and TARO ZYX 3 AXIS GYRO for HK250. TX is DX6i.
Swashplate type:1servo NORM
Reverse:AILE-R, ELEV-R, PITC-R
The system menu:
1 flash direction gyro--- Direction 1*
2 flashes Parameter group selection--- Yellow ,2 flashes: 3Dmode
3 flashes Dervo type--- Yellow ,3 flashes: all 1520us digital.
4 flashes Swashplate type--- Yellow ,2 flashes: 120 degree CCPM*
5 flashes Pirouete optmization--- Blue ,1 flash: negative*
setup menu: All Factory default setting.
(Probably it seems that these setup can be performed by TX.)
However, although it is a setup of Direction 1, the manual is differed from, and if the LEDs panel side is not mounted as the undersurface, GYRO compensation of ELEV does not work correctly
You are also the same mount...
