GRT Avionics

I have purchased GRT servos to install in my Murphy Rebel (just because I can). These will be driven by my GRT Sport. I am a little concerned about the apparent drag from the servos. The Murphy is not what I would call "trim stable" In other words it does not eagerly try to return to a tri...

By looking at the pin-out listings of both the GRT Sport, and the Garmin GTR200, it looks like I should run a wire between pin 37 on the Sport (labeled as TX4), to pin 24 of the Garmin GTR200, labeled as RS232 In. The Garmin pin-out shows a pin 23 as a RS232 out. Given that the GTR200 is just a com,...

Thank You for the advice. EE is not my native language. All the help I can get is appreciated. I am quite thankful that I an not trying to hook up one of those quite fancy panels you see on display at Oshkosh. Mine is pretty simple, but will be a chore for me.

This is probably a very basic question, and will reflect my lack of understanding of many things, but here we go: I am making up the wiring diagram for my Murphy Rebel project. I am using the Sport 8.4" with the EIS400, the Garmin GTR200, and the Sandia 165 transponder. I am struggling with the...

Interesting point about the EFIS or the interconnect wiring failing and shorting to ground. Your point out that the resister is there to prevent grounding the mag. I had been planning to tap into both mags so that on a mag check I would maintain the display of the RPM, but maybe the wiser move is to...

Does the installation of a resister tapping into the P lead of a magneto to the EIS unit interfere with the conducting of a magneto timing check? Typical procedure is to hook up the timing indicator, turn the mags to "ON" (which is really un-grounding the mags) ((and yes, the sparkplugs ar...
