if you have the AVCS to on position and you have a computer TX make sure the Revo is turned off or INH.
i have the 240 gyro on my hornet when i first set it up i plugged the servo into the reciever where the gyro plugs (channel 4 on mine) turned on the TX then the heli and centered the servo horn. then i removed it and pluged the gyro to the reciever then the servo to the gyro. i made sure the the gyro AVCS was on. and the gyro Gain was at 50% factory setting. it works fine i havent made no other adjustments since.
the reverse on TX and gyro are probably both the same it just reverses your servo movement. you should notice the difference . maybe go search RCU and look for your problem or 401 setup or your TX settings in the shogun threads. thats where i found my Tx settings for my hornet
