    Dynon Install guide vs Wiring Diagram (for Pitot)

    Yeah I think I am a going to move some stuff around. That pitot can definitely go on pin 9. I realize this is topic creep, but any suggestions for a best pin(s) for lateral and pitch trim indications? It’s all Ray Allen. I was thinking maybe 10 and 11 since I don’t fly a retract. I also have...

    Dynon Install guide vs Wiring Diagram (for Pitot)

    Installing EMS firewall forward interface where previous Trutrak was

    I purchased a firewall pass through kit and am interfacing the thermocouples direct with the unadulterated kit-supplied thermocouple harness. I made a tray for the EMS that resembles the box that was used for the Trutrack. That part is kinda cool, but you gotta have it high enough so that it...

    Installing EMS firewall forward interface where previous Trutrak was

    Installing EMS firewall forward interface where previous Trutrak was

    My RV-10 has a TruTrak firewall mounted EDM interface for the engine sensors and thermocouples. The EDM mounts to the firewall aft but has a firewall forward interface. That interface uses a standard 2-1/4 punch through with a stainless steel plate with the two DB25 pin connectors integrated...

    Ray Allen T3-12A trim actuator with Dynon HDX

    Thank you for the quick reply. Since I have the trim amp, I may go ahead and install it since I have everything opened up (sigh). Especially since I would have runaway trim indication.

    Ray Allen T3-12A trim actuator with Dynon HDX

    Hello forum, I am in the throes of installing my HDX system in my flying RV-10. My 10 has the Ray Allen T3-12A Elevator Trim actuator. My question here is, do I need the Dynon Trim amp to run the elevator trim or can I forego that in this particular application? Thanks in advance, Mike
