MGL XTreme mini EFIS Generation 3 is a comprehensive flight, engine and full autopilot head. 

Now in its 3rd generation, the MGL Xtreme G3 EFIS has a new compact body with improved brass pitot and static ports.

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, crisp clear display and a 65 channel high performance GPS system (aerial supplied).

Able to connect to existing engine sensors (or add additional sensors) via an optional MGL RDAC module mounted in the engine bay. It will also connect to the SP-7 AHRS horizon module and SP-6 compass. Without these sensors the horizon will still work by using software based GPS track derived information and the heading display is the GPS track. On top of all that, the XTreme EFIS can act as an autopilot control head, you just need to add MGL servos. 

The XTreme is designed to fit a standard 3.1/8" / 80mm 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 it will operate from 9 V to around 28V.

We ship worldwide. At checkout you can choose from low cost airmail options and express courier services like DHL or FedEx.

Within the UK we normally dispatch using Royal Mail or DHL. You choose the level of service at checkout.

VAT sales tax (20%) is included in the price displayed on the website. This tax applies to UK customers and EU customers. It will continue to apply to customers in the 27 EU member states from 1 January 2021. This is because we are located in Northern Ireland. The Northern Ireland Protocol, agreed by the EU to facilitate cross border trade with the Irish Republic after Brexit, also applies to the rest of the EU.  We continue to charge the UK rate of vat to customers in the 27 EU member states and there is no further tax to pay upon delivery. We can continue to zero rate the vat for EU business customers who enter their vat number at checkout. 

Customers outside the EU do not pay vat and the tax will be removed at checkout. Local import taxes may apply - check with your local authority.

Currency. All products are priced in Pound Sterling (GBP, £). Using the "Currency" tab you can change the displayed currency to either Euro (EUR, €) or US Dollar (USD, $). This is an indicative exchange rate, automatically updated daily and is based upon the prevailing bank rate. The price you see may be displayed in USD or EUR but payment processing will be conducted in GBP. This means that your card issuer will apply their usual exchange rate, which is likely to be different from our indicative rate. 

What do you get for my money ?

You get the XTreme instrument, wiring harness, GPS aerial, OAT probe, 2Gb SD card and pitot/static fittings. This is a very comprehensive flight instrument out of the box and without the optional peripherals such as SP-7 AHRS and SP-6 compass modules. The internal GPS and software will generate the horizon based on track prediction and this is very effective up to about 30 to 40 degrees of bank. The track heading is also provided by the GPS. The only areas that don't function without the optional peripherals are balance ball, G-force and wind speed and direction (you need the SP-6 and SP-7, see 3rd paragraph below). If all you need an artificial horizon for is the ability to keeps wings level in poor visibility and execute a 180 degree turn to get out of trouble, then this is a very complete, low cost solution.

To enable the EMS engine monitoring 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. There are a selection of RDAC engine modules available. The RDAC-XG for most 4 cylinder engines including the Rota 91X series. The RDAC-XF adds more inputs and can cater for a 6 cylinder engine and if you want manifold pressure, the RDAC-XF-MAP adds that function to the basic RDAC-XF. We also have specific RDAC modules for the Rotax iS injected engine and the UL Power range of engines. 
Whichever RDAC you choose, it simply connects to the EFIS via a single twin 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. 

If you require the higher performance artificial horizon afforded by solid state gyros, then the SP-7 unit simply connects to the XTreme and is remotely mounted somewhere within about 2ft of the centre of rotation and close to the centre-line of the aircraft. The SP-6 will provide the compass, and it is best located away from anything magnetic or ferrous, usually 9" is sufficient distance. The software will calibrate-out any small discrepancies, so no need to be too paranoid about location. It can be mounted side-by-side with the SP7 (or it can be mounted anywhere, even in a wing tip if necessary) and it can share the data cable and power feed.
The internal GPS, as mentioned earlier, will drive the horizon display. It also gives you the ground speed and there is a database installed covering the whole of Europe for waypoint-to-waypoint navigation. 

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 SD card is also used for firmware updates, which are free.

In 2014 a free firmware update enabled the XTreme to act as an autopilot. You need to add MGL servos and an SP-7 AHRS module for this to work.

The XTreme will monitor flight and engine parameters and provide clear warnings should anything stray from the user's pre-set levels. The LAA's John Brownlow, writing about the XTreme after evaluating the Gropo Trail, in the official flight test report, wrote the following: 

"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."
