Gy 401 HH Holes Then Lets Go

[rc heli 55]

Today was a Little windy. I put the heli down wind, tail facing me GY on HH getting ready to flip it when the heli turn in to the wind. I try it again but the same thing happen but I try to put in some right rudder but it didn't work.On the ground I was able to turn right with no problem. I brough the gain up from 60%,70%,75% and 80% and it did the same thing. Its holes about 10sec then lets go. This is the first time its happen to me. I had the GY401 7yr. my servo is 9254. the wind blowing from 20 to 25 mph can some tell if the GY is going out or the servo.

that's not really enough to determine what's causing you trouble, however you can check a few things, and set it back up from scratch.
You want the Limit to be in the 80% to 100% range for the gyro to work properly. Adjust to a different hole on servo arm to get there.
Start with gain high enough to get wagging in a hover, and lower it until it no longer wags. You should not get below 40% gain in my experience.
Another thing to check is battery voltage! If you have a cycler, run a sequence and see what the mAh is and compare to the rating of the battery. OR you may fly a bit and check voltage and note any excessive voltage drop. Anything less than 4.8V will reset the gyro, meaning if all servos in use at once drop the voltage to 4.8 or lower, you WILL have problems.

Put in new servo the heli is working fine now. GY setting is back to 60%
wind blowing 22mph . So the servo was not working right.

Thank you WayneBrown
