This is an attempt to gather information on an annoying problem with Trio Pro Pilot.
What follows is a message to their tech department...
The system is self engaging, sometimes altitude hold some times both servos.
About two months ago I spoke with someone in your tech department and a file was created on the issue. It was decided at the time to gather more data to help come up with a cause of why it was occurring.
Initially the orange wire at pin 31 and yellow wire at pin 34 were not hooked up. (remote disconnect) and the thought was if these wires were not shielded in the bundle where they were located, it could cause a problem. The wires were shielded and are now connected to a single switch to ground for disconnect of both servos when button pushed. It also works to activate PCS.
The system is continuing to self engage. Sometimes just altitude hold, sometime both servos. The engage lights are on when it happens. It always happens in the traffic pattern. The system disconnects immediately if the engage buttons are pushed or if the remote disconnect button is pushed. It has self engaged altitude hold during the flare. Yesterday it self engaged during take off!!
For now I am implementing a procedure to have the on-off switch "off" for take off and landing.
Have any of you reading this post experienced the issue?
Thanks. We need some answers.
