Pitot in tail of Waiex

[Spaceman]

Do any of the commonly used iEFIS type glass panel systems accept inputs from an LRI so you can display the info on the screen instead of the analog gauge? I haven't really put much thought into avionics at all yet but I bought an LRI kit and put it in the left wing inspection panel and ran the tubing to the wing root way back when I built my wings.

I figured I'd decide how to use it later but if it could be integrated into a glass panel that would be pretty slick. Then again the analog gauge is a good backup if the panel fails; you could probably fly with nothing but the LRI if you're VFR...

Do any of these LRIs offer any kind of audible output? I don't suppose it would do much good with everyone wearing noise cancelling headphones these days.

Grand Rapids Technology units have an Angle of attack indicator that may help you out. They also have audio warnings that can be downloaded for the efis. A stall warning may be one of them. I purchased a GRT sport EX system but have only scratched the surface on wiring and learning all the stuff it can do. I'm still designing my panel and have a spot leftover on the right side to figure out yet. Seat heater switches and ELT indicator fit under the radio stack. Thinking about trying to get a kindle running as a second display using the GRT remote app.

Looks nice so far! Now I'm getting way off topic but where are you putting your pitch trim knob? So far that's all I have on my panel and I just copied the factory plane's location in the upper left corner of the panel.

Well it may be over the top and just another bell or whistle, but one of the rocker switches on the left side of the panel will be operating a linear actuator to be positioned under the seat pan for electric elevator trim. I have DIY indicators for flap position and elevator trim position next to the switches. I looked at hat switches for the stick but they were crazy expensive. I don't remember the price exactly but I think my rocker switches were under 10 bucks. I just didn't want the big red knob on my panel. The bargraph is a DIY indicator for fuel quantity. It will just act as a backup for the EFIS indicator. I'll use a probe for the bargraph and the EFIS can calculate quantity using fuel flow as well.

Oh wow that's awesome! Ok so going even further off topic, if you're putting the actuator under the seat, are you going to build in some kind of access panel in case you have to get at it later?

I want to eventually put in a simple autopilot but I haven't yet addressed how I'd ever access the aileron servo once the seat pan and floor are both riveted on. I'm not sure why they made the seat bottom so permanent on the B model compared to how the legacy seat is attached!

For what it's worth, seems I remember someone installed their roll servo in one of the wings out by the belcrank.

The MGL iEFIS system will do an LRI with audio output which can be fed through the intercom into your headset. For at least the iEFIS lite which I have, you need to purchase the iEFIS Extender which adds AOA, 4 additional RS-232 Ports and analog inputs for $250

I've got a drilled out rivet on my Legacy Sonex wing above the plans built Pitot-static tubes. Hasn't flown yet though...

For the trim knob, I have installed a vernier that is normally used for the prop governer. I haven't flown yet but it seems to work fine in the hangar. It is located by my left thigh.
