NT-400 Head Lock Gyro FAQ
Question 1 :
How does the gain adjust-screw on the gyro works with the gain setting on the Transmitter ?
You have two methods setting the gain values of NT-400 gyro, they're not conflict with each other :
1. If you're using the receiver that is less than 5 channels, then you should have no spare channel to plug the gyro's gain setting wire in. In this case you only can use the adjust-screw on the gyro to set the gain values. The more percentage you tuning, it is more approximation to the Head-lock mode.
2. If you're using the receiver that is more than 5 channels, then you could put the gyro's gain setting wire into the 5th channel of receiver, and adjust the gain values by your transmitter. In the meantime, the adjust-screw on the gyro will be disable automatically.
Question 2 :
Where should I install the NT-400 on the helicopter ?
Ans : You can reference the following pictures.
Question 3 :
For some reason I have to put the gyro up side down, otherwise it's working in the wrong direction. Is this normal or is there anyway to change this?
We think maybe you're met one of the two cases in the follow :
1. If your helicopter was "spin" when it take off. Then you need to put the Gyro up side down. (This NT-400 has no " Normal/Reverse " switch, so you only can put it become up side down to solve this problem. But our another Gyro A500-G, it can be reversed the sensor's signal by a DIP switch on it).
2. IF your helicopter rudder's servo was moving in wrong direction. Then please change the normal/reverse setting (Channel 4th) on your transmitter. And remenber next time you change to other servo or change servo's install direction, you may need to re-check it.
