Another option is that I search for a used D120 in the UKÖ

Any ideas?!


Hi Rob,

Not sure what you are planning to use for your GPS navigation, flight planning, traffic and weather display, and autopilot, but something else to consider is a standalone GDU 470 navigator with GEA 24 engine monitor.

You could start with just the GDU 470 and GEA 24, and expand the system as desired to include additional functionality such as the autopilot in the future if you wish.

If you already have a 3rd party autopilot, the GDU 470 will support flight planning and a NMEA RS-232 output to drive that autopilot.

Personally, I would rather spend a little more (if necessary) to start with pieces that could be used to build upon a more complete, highly integrated single vendor system in the future rather than investing in pieces from multiple vendors.

Wouldn't it be nice if the G5 could display engine data from the GEA 24?!

Thereís no doubt the functions available on a modern glass system are incredible, but Iím determined not to make mine an airliner - personal choice. Iíll be flying VFR for fun, enjoying the view out of the window! Basic instruments, radio/xpdr, and an iPad / chart for nav is what Iím after. The trick is trying to keep the ďclassicĒ look without too many jazzy bits of kit to clash!

Yes, at times Iíve found it hard to justify not going glass - resale value, capability, etcÖ but I just donít think I want it! Just give me a silk scarf and some goggles!

A stand-alone EMS it isÖ. This week, at least!!

You can do everything you want with glass and even with some have it mimic a 6 pack. A single 10 inch screen can give you amazing capability. Itís also been one of the biggest safety advances available in the experimental world. The capability to display traffic, obstacles, terrain and the ever growing TRF areas should not be underestimated. Instant access to information you will spend considerable time heads down looking for in a traditional cockpit is another vote for safety!

I think the OP made his point about his philosophy pretty clear...

I'll keep following this thread since my ageing (good I'm not the only one ) VM1000 will, sooner or later, need replacement...

We have a GRT EIS Model 3 on the -8, and flew with this one only since the Chelton EFISs were u/s. Using only the GRT EIS is a pain since one has to keep pushing the Next/Ack button to get to the required data... We now got rid of the Cheltons and installed 2 Sport EX screens with which we are very happy with.

Maybe a solution might be from GRT with 1ea EIS and 1ea Sport EX dedicated as an engine monitor?

I think thatís exactly Mikeís suggestion back in an early post, except he suggested looking for a used HS or WS display. If you can find one used, it wonít be too expensive, because you only need the display - the attitude sensing parts were separate boxes.

What is it you donít like about the MGL? I installed the Blaze to keep the look of the round gauges as well. I am now adding the RDAC to get EGT & CHT on all 4 cylinders. I have OP, OT, RPM, Voltage and fuel pressure. It has a built in flight timer that is activated and stopped by the rpm reading. It also tracks maintenance (oil change) based on flight time which is really run time as it starts tracking time at a low RPM. You can wire an alarm annunciation, either aural or light when limits are exceeded. My original issue was that you donít have everything on the screen at once. The rpm, volts and CHT/EGTís stay on the main screen but pressure and temp readings scroll. After a couple of flights I appreciate the layout simply because I want to be able to glance and not navigate a very cluttered screen. All in all I like it since itís a 3Ē round gauge.

I am with Walt. The EI CGR 30P is an awesome unit. Works great and a beauty to behold. I too didn't like the price when I ordered it but after flying it for the first time I was super glad I went with it. I wouldn't hesitate to do it again.

Just to come back to the thread since thereís been recent postsÖ I ended up getting a barely used Dynon D10-EMS for a good price.

The unit itself might not be cutting edge but it tells me everything I need it to. Hopefully Iíll be happy with that! Thanks everyone for their input.
