Hiec HG3XA gyro set up questions
I installed a HiTec HG3XA stabilizer into my Estrellita EF1 pylon racer and I"m having 2 issues that are not covered in the manual and I need some help.
Gyro location is not per the manual:
My root chord is about 10.5". The center of the gyro is about 3" behind the CG. I can't put it on the CG because the flight battery is there. Maybe that my issue but it seems like it should still work.??
After plugging in my flight battery, I let the gyro initiate. Then I flip the 3 way switch several times so that the center is all set up. It should be ready for flight. I take off with the switch in the middle so the gyro is turned "off" and the plane flys normally. Pylon style turns are just right.
( NOTE, I'm not using the gyro on my rudder. ONLY use it on elevator and aileron.)
Then after a few laps I turn it on in "rate" mode. (normal mode?)
Suddenly my turns are really long and wide. Like the gyro is limiting my servo travel to less than my commands.
I go back to "off" mode and the plane returns to normal behavior.
In Heading Hold, the plane turns TOO TIGHT. Like the gyro is making the servos travel MORE than my commands.
I started with the gains really low and increased them over a few flights until they are almost all the way up.. Changing them doesn't seem to help.
I'm running a Spectrum DX8 TX.
Travel for elevator and ailerons is at 100%
I limit my throws using the rate switches and fly in "low" rate.
Elevator- L/R 40% up/25% down (30% expo) This gives me about 3/16" up travel. That's all it needs at full speed.
Aileron- L/R 70% (30% expo)
