MGL XTreme EMS G2 and RDAC-XG Bundle

£ 750.00(857.43 €)
MGL XTreme EMS G2 and RDAC-XG Bundle
MGL Stratomaster XTreme EMS



This low cost unit is based on a 4.2" sunlight readable, wide viewing angle, high resolution LCD display. It integrates SD card reader, function buttons, rotary control, and display.

Requires one of our RDAC engine modules that you install in the engine bay. All existing engine sensors can be attached to the RDAC module and you can add extra sensors to expand the functionality. The RDAC connects to the XTreme via a simple two wire CAN bus, so no bulky harness passing through the firewall.

Able to connect to existing engine sensors (or add additional sensors) via an optional MGL RDAC module mounted in the engine bay.

The XTreme EMS is designed to fit a standard 3.1/8" round instrument hole. The body is located off-centre allowing the unit to replace instruments on the right side of a standard 6-pack configuration or any other location that currently occupies two instruments.

Due to the light weight and very low mounting depth no complicated mounting brackets or trays are needed. Power use is low and operation from much less than 12V to around 28V is fully supported without further items required.

The XTreme breaks new ground in current un-certified (experimental/ permit to fly) EMS technology as it is a universal platform and can run many different MGL application programs, much like you can do on a home computer by installing different software. This means that functionality is not fixed to what you have at the time of purchase (like a Dynon EFIS). There will be upgrades to existing application programs, and it is likely that entirely new applications, that extend the area of functionality into new regions, are posible in the future for this remarkable, highly flexible unit.

So what do you get for £750.00 ?

For £750.00 you get the XTreme EMS instrument, wiring harness, OAT probe, and 2Gb SD.

To enable the EMS functions you need to add an engine module (RDAC) and install it inside the engine bay, usually on the firewall. You will probably want to monitor CHTs, EGTs, oil T&P, RPM, Fuel Flow, Fuel Level, and possibly even Coolant Temp. You can monitor and display up to 6 cylinders. The RDAC for this level of functionality is the RDAC-XF, which is £228.00, but we also have a cheaper 4 channel unit suitable for Rotax 912 and other small engines. It cost £149.95. Whichever RDAC you choose, it  simply connects to the EFIS via a single supplied cable, so no bulky wiring harness to accommodate through the firewall, and hooking it up to the engine is easy because you are able to mount it in a convenient position. The RDAC and XTreme will interface to virtually all senders fitted to any engine, and we can supply the additional senders you may want. We have a couple of alternative RDAC units for more engine sender flexibility, so if you want to measure something else, for instance manifold pressure, we can almost certainly accommodate it.

The SD card is used to record "black box" information and a flight log. The data can be downloaded later from the card and displayed on a PC.

The XTreme will monitor engine parameters and provide clear warnings should anything stray from the user's pre-set levels. The Groppo Trail (see photos below), which recently (2011) went through its flight trials with the LAA, has an XTreme EFIS fitted, which is the same as the XTreme EMS but it also has full flight instrumentation. The LAA test pilot, John Brownlow, actually passed comment about the warning alarms in the official flight test report. This is the paragraph from the Flight Test Report...

"MGL Avionics EFIS Display

The MGL Avionics EFIS displayed a very clear visual warning in red, in the screen centre as low indicated airspeeds were approached. This was the first EFIS display used by the test pilot that gave such a dominant warning. The warning was assessed as a most useful safety benefit."

To sum-up, the XTreme EMS employs state-of-the art electronics in a compact and very light (260g) package. At first glance this is instantly apparent just by comparing the clarity, definition and brightness of the screens. In this respect the XTreme is remarkable. Numerous visitors to our MGL Avionics display at the Sywell LAA Rally, Aero Expo and the Flying Show commented very favourably upon that aspect.

It's also remarkable in many other ways - please call me, Paul, on 02892667187 to discuss.
