Hi All,
I have TruTrak Autopilot Vision 380 bought new around 5 years ago. The set is installed on RV7A and worked perfectly first 2 years after installation.
Approximately 1 year ago the roll servo stopped working properly. I supposed the problem was in servo and I bought a new one and replaced the original one.
Unfortunately it didn’t help and the problem is the as described below.
1. All altitude functions of AP work properly. Also roll servo works good on ground - the result of ground test described in the manual is OK.
2. In the air the roll servo works in the way like it would be “to weak” to do it's job.
3. Usually the initiation of turn (new heading) is done properly but due to “weak” signal or torque servo cannot stop the turn in the indicated hedging and the aircraft continues it.
4. If I keep the steering wheel I can feel soft movements but not strong enough to stop the initiated turn or keep requested heading.
5. In case of direct flight - is continued till the aircraft is moved by stronger turbulence.
Could you please help me to identify the problem? Thank you.
