Gyro moving servo while still
The stock gyro seems to be causing the servo to move the the maximum position if no stick input is recieved. This causes the heli to piro slowly. I can counter this with stick but clearly there is something wrong with my setup. Is this a know issue with the esky servo?
What are pointers for troubleshooting the gyro? |

Hi, welcome to Belt CP forum. Could you give more information about your heli, please? I suppose it's a Belt CP, since you found us here Is it v1 or v2? v1 had a silver tail servo, v2 got a purple one.
What you're saying about the servo going to the max probably happens on the bench, if it happened in the air it would cause quite a violent piro rather than a slow one. Hmmm, v1 probably wouldn't do it on the bench as it was a pure rate gyro, so you're probably dealing with v2, which is a heading hold gyro, albeit a very bad one. Are you using a stock Esky radio, or you have a computerized one? If it's stock, is it 72MHz or of the newer 2.4GHz variety? We'd need more info to give you a bit more specific advice...

Thanks for the reply and sorry for not including enough information.
I have a Belt CP v2 with the purple esky gyro. I am using a DEVO8 with a walkera reciever. The servo moving occurs while the heli is on the ground and is slow. While in the air the heli will rotate a 360degrees in about 20-30 seconds unless I input the rudder. It seems to take about 1/2 of the stick to hold it steady. I have tried adjusting the linkages and servo location but the the same issue occurs. Thanks! |

Look, you have a half decent radio, so you could put an inexpensive MEMS gyro, they run $10-$15 these days. The stock purple gyro is a hit-or-miss, looks like yours is not calibrated properly from the factory, and AFAIK there in no user-end calibration for it. In the meantime, you could just trim it a bit with a rudder trim, it's a no-no with decent HH gyros, but it works (sort of) with purple Esky one. I don't recommend flying like that too much, my experience with purple HH gyros is they break the lock easily and send the servo slamming to one end... Definitely look for an inexpensive MEMS gyro.

Can't trim it Jerry, it is taking half stick to hold it steady. Go along with everything else though.
Cheers Sutty

I remember when my esky purple giro quit mid flight...lots of damage dump it now and go with the mems assan giro good price and fairly good giro for sports flying but prob not 3d I have one on my tr250 and my hk450

Hey,
Not sure if your issue is resolved, but its normal for a head lock gyro to move in one direction. To cure the piro you need to make sure that you first setup your tail in rate mode to do that you need to move the knob on your transmitter in the direction when the light on the gyro shuts off and move it further below like till its pointing 8 o'clock. Now make sure that the tail servo is 90 degrees as much as possible. Now move the servo towards the frame so that the tail blades point towards the paddle and have some default pitch instead of zero degrees pitch at centre rudder stick. You will have to play with the servo position to get rid of the problem and then go back go HH mode. Hope this helps |
