RE: DX7 & GY401 Setup Issues
I don't use the gyro sense menu I use gear endpoints but I can close the deal for you very quickly if you want to follow my way. I am assuming you have your gain in your gear channel not AUX2.
1. Get into model select. (Hold Scroll down + Select when turning on radio.)
2. Scroll down to INPUT SELECT and set GEAR = GEAR not GEAR = GYRO. (Bye bye gyro sense menu)
3. Push Scroll down + Select to exit model select menu. Push Scroll Up + Select to get to Function List. Find Travel Adj. Scroll Down + Select will put you in it.
4. Push select until you get to GEAR. Set that top value to 50. Usually you will be around 45 - 60 let's start with 50.
5. Pull the gear switch down to be able to set the L value. Set this lower value to 0. (I don't use rate mode except to setup my gyro so I want no gain.)
So it will be GEAR H: 50 L: 0 or whatever it looks like in the radio.
Now to adjust HH mode gain your switch must be up. Always start the heli with the gear switch up then move it to rate mode to setup the tail otherwise it won't initialize properly. If you ever want to reset your gyro click the gear switch 3 times quickly (within 1 second of each click) ending with it in the up or HH mode position. Again never ever start your heli with that gear switch in rate mode.
Hope that helps.
