RealSimGear GTN750 vs Real Avionics vs Home Grown review

This is a comparison/review of a Real GTN 750, the RealSimGear and my own home made GTN 750 (both running the RXP in XP11).

Note that I also used Air Manager with an Arduino for part of my project as you will see.

All in all I'm really happy with my solution. Any questions, please ask!

So you use the reality xp software they made for the 750.?

For information, the GTN series has had an update. The new models end in xi. They have upgraded screens and processing so even more responsive.

Did you sort out the colour markings on the buttons? I can 3d print these duel colour for you if required

I too have been debating the RealSimGear GTN 750, a screen with Air Manager, etc. I hope you can answer a few questions. What iPad you are using? How did you get the iPad working with the knob? Would you mind making a how to video on this setup? The Arduino connecting to the button and iPad blows my mind! This might be the best way as responsiveness is my biggest concern. Thanks for showing this.

Nice work! How did you manage the FPS drop using that setup? Thanks in advance.

Where did you get the3d program for G750 bezzel?

Interesting. Been debating on getting the realsimgear 750, I use one in my irl flying but seeing that touch delay is a bit concerning. Glad I caught your review.

Nice work on the home made GTN. Hoping you can answer a couple of questions for me:
- What software do you use to get the GTN 750 on the iPad? Spacedesk or something else?
- Do you have the link handy for the dual gang pot?
Many thanks!

Hi, Will you have the GTN 750 STL for sale with the relal measurements?

[manic_miner]

Have you tried the TDS GTNXi 750 on the Real Sim 750 unit and is it more responsive?

Nice tutorial.... Thanks for sharing this What size screen is your I Pad???? Thanks again

[lovelyapple]

where did you get the bezels file of G 750?

What 3D printer do I need to do this? Thanks!

[philipjensen]

nice work! what is the screen for the altitude alert?

[christophermartin]

Just font think the janky iPad setup is any better than the realsim gear one. Also tested the touch responsiveness and its just as laggy (worse, sometimes becsuse of the remote screen latency) than your video shows the real sim gear one to be.

You can see it in your video too.

Actually in checked and asked many other users. I guess your unit has some problem. Almost everyone told me that works flawlessly.

GARMIN GTN 750 - $17, 000 USD....Real Sim Gear GTN 750 - $500 USD, so it is difficult to compare!!!
