Voice of experience here: We have the MGL Xtreme EMS fitted. The RDAC is in a sealed box rather than open as shown here and is mounted on the engine side of the bulkhead. It took us two years of chasing a temperature reading issue (EGT and CHT would instantly jump into the red, reading way too high) to finally get it sorted. To cut a very long story very short, directing a cool air feed onto the RDAC sorted the issue. It now runs totally stable.
Sounds like a wrong cold juction compensation on the thermocouple connections. If they don't use compensated connections (like it seems), small temerature fluctuations will cause teperature inaccuracies. Hence why you can't extend thermocouples with standard copper wire.
This MGL is not really a brand that took off. It has been draping for long time. I went with Gaming G5. Solid unit, really easy to install and no problems whatsoever. Guess what? cheaper than this MGL thing. Thanks for the reply anyways. From now on only Garmin on my aircraft. A true avionics engineering company.
i like your video, im still figuring out what displays ill put into my verieze, im using a continental 0-200 and that is a very popular engine should have a lot of equipments that will work with it.
Wow the MGL miniEFIS does darn near anything in a tiny package. I mean I guess they all do these days, I'll be looking at them in more depth. Thanks for the video.
I agree with Michael Tucker. Screw terminal connections are Pre WWII technology. They aren't used on modern avionics, due to the increased likelihood of a future failure of the connection point. While this connection method offers ease of installation, it does so at the cost of future reliability. Doe the MGL system offer strain relief for the wires going to that terminal [RDAC] box? Perhaps via the cover mentioned by Rob Pritchard?
Every house in the country uses screw terminals for vastly higher currents than this. With the risk of house fire at night being obvious. It's a matter of assembly skill and attention to detail. MGL avionics are very inexpensive comparatively. They seem to be made for LSA, daytime, VFR only. Yes, they have autopilot. But they clearly state on their website that their equipment provides accurate AHRS data, it should not be used for primary data in Actual IMC. This brand is probably aimed toward Kitfoxes and Rans. Not Vans RV or Long-EZ type cross-country machines. MGL offers a fantastic 7" portrait iEFIS with their fully customizable screen for only $2200. 😮😮😮
@EllipsisAircraft Your argument of being used in homes is irrelevant. Houses do not move and do not experience the same levels of vibration that Vehicles do This lack of vibration is also one of the reasons that you could use solid core wire in home wiring and you cannot in vehicle wiring. Screw terminals in a dwelling do not get exposed to the vibration levels that they do in a vehicle.
Good vid thanks but I agree with Ron Allen on the canbus comment Good thing about using can bus you daisy chain each connector,this gives massive scope Eg I am installing MGL iefis and ems into my build can bus 1 has all the info modules ahrs ,compass etc wth 5 connectors running of. Canbus 2 has a further 5 connectors feeding iefis ems rdac ecb ibox etc. by keeping all the daisy connectors the same pin outs then the whip cables are made to match the modules it’s easy to change out any component ,all you need to do is make a new whip to plug into the daisy chain connector to feed the new component
My point is that this TIP video was ONLY about Engine Sensors - there is no can bus for them. Your comments about the value of can bus is excellent- but that has little to do with engine sensor connectivity. That is another topic altogether. The point of the video is to look at engine sensor connectivity methods: screw terminal or custom cables. It is up to the liking of the builder to choose.
What is your take on the reliability of your MGL EFIS? Have you had any problems with it? I am interested in the AI (aerodynamics only) no engine monitoring. thanks in advance, best regards.
Actually, the Garmin is no different from the Dynon regarding this topic. The Garmin GEA24 is the interface (using custom cables) between the sensors and the display. The can bus is the communication from the GEA24 interface and the rest of the display system. You still need custom cables made for your sensors.

My first thought on the MGL screw-terminal approach: does engine vibration result in the terminal block screws loosening?
I agree with Michael Tucker. Screw terminal connections are Pre WWII technology. They aren't used on modern avionics, due to the increased likelihood of a future failure of the connection point. While this connection method offers ease of installation, it does so at the cost of future reliability. Doe the MGL system offer strain relief for the wires going to that terminal [RDAC] box?

Jhon You are good thanks for all the info you provide
Good afternoon sir , thanks a lot for this informations ,
Best regards
Good vid thanks but I agree with Ron Allen on the canbus comment

Eg I am installing MGL iefis and ems into my build can bus 1 has all the info modules ahrs ,compass etc wth 5 connectors running of.

Good to know info.
Do you have a video showing the options to install ADS-B ?
What is your take on the reliability of your MGL EFIS? Have you had any problems with it? I am interested in the AI (aerodynamics only) no engine monitoring. thanks in advance, best regards.
Very well done!
I love it!!! ' There's no time like now..... to get back to building!!!!' LOL...
James Bond glasses will do the job :)
How is that RDAC sealed from elements? Seems you would at least want a splash cover.
The photo is not a production model.
Useful video us usual, 5:18 where can I get all this instrument
Looks to me like the Zenith Aircraft Company dynon kit. Go check out thier website. IIRC I've seen that pic in one of their videos.
非常棒！
精辟！
Specially made parallel port...
You forgot to mention can-bus which is used by Garmin and is the standard used by most commercial aircraft installations.
Actually, the Garmin is no different from the Dynon regarding this topic. The Garmin GEA24 is the interface (using custom cables) between the sensors and the display. The can bus is the communication from the GEA24 interface and the rest of the display system. You still need custom cables made for your sensors.
Here is another engine monitor. This one is very simple / yet modern
