Add to Wishlist
Part# 11-10393


The XTreme EMS is based on a 4.3" sunlight readable, wide viewing angle, high resolution LCD display. It integrates an SD card reader (for software updates and for engine data recorder), 5 function buttons, a rotary control.

It can be connected to standard MGL Avionics RDAC (engine monitor) boxes (required).

The XTreme EMS is designed to fit a standard 3 1/8" round instrument hole. The body is located off-center 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

to work with Rotax 582, you need something like RDAC XF or similar (page 19 in RDAC XF install manual) . it will get all the signals from the Rotax 582, then the RDAC will send the info to this MGL to display.

One of the more stable EMS products I have used. Bright readable display and monitors engine parameters very precisely. Installed in Pitts S1-C biplane with O-290 and bubble canopy. Fits well due to shallow mounting depth. Once calibrated the fuel flow and totalizer great alternative to hard to see sight gauge.

Bright, easily readable display. Display setup options are good. Alarm functions provide safety. Ability to interface to almost any sensor.
