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 ?
Ans :
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?
Ans :
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.
