Hi,I have a spectrum dx8 radio that I would like to be able to adjust the gain on the knob switch on this radio.The gyro I want to us the power box 3e gyro which requires you to set up gain using either or a slider or a knob switch to set the gains and than when you have them right transfer the gyro to a three position switch to select heading hold or damper mode or off.Thanks JeffClark
