This year in Oshkosh I saw this new feature, it's another avionics that connects to WiFi with the iPad, but this one has autopilot, it's not an autopilot that acts directly on the commands, this one acts on the trim tabs with an advantage since when it's off works as autotrim like the Airbus airplanes:

I think this avionic with 2 or 3 displays and a backup altimeter, climb and speedometer could be an very affordable glass cockpit.

The problem is that the dedicated displays are just super expensive tablets that run only 1 application, to work they need all sensors and accessories, making a quote with TALOS system (with ADS-B), autopilot, transponder and VHF separated I got $4600, that's just a little more than just 1 display. Adding more a speedometer, climb and altimeter instrument I would have a reliable instrument panel for 5.5K for only VFR that could be safe for an accidental IMC. I m not sure I understand you, the above unit I showed comes with the display for under$500.

Do you have evidence of such interference from these autopilot systems? Conjecture can be useful to point you in the right direction sometimes, but it proves nothing. You also have to understand the paradigm changes for different pilots and flying conditions. For a VFR only pilot who flies only in daylight, autopilot isn't necessarily a mission critical item. It most likely isn't going to affect their flight safety if the autopilot doesn't work, so the impact is very different for different pilots and their situations. That makes the cheaper autopilots a much more useful and attractive option for simple VFR pilots. Also understand that much of the difference in cost is often due more to onerous FAA certification requirements than it is to product quality. Certainly the risk is higher in a system that has undergone less testing, and that's something to consider, but the potential impact can effectively mitigate that concern. Now if you have evidence that any of these devices cause radio interference, that's useful information, so please present it. I'd be more than happy to hear about it, as I'm sure others would here as well.

I think he big question is perhaps whether this autopilot that works only on the secondary surfaces if it really works or can put the plane in a PIO-type oscillation?
I hadn't even thought about this issue of interference, but it makes sense since a device that depends on wifi on board can both promote and suffer interference, but I've seen videos of MGL-type avionics having problems in flight, I have no idea how often this is it can happen, but a traditional system usually sells the display for something around 3k and puts the sensors together to make everything work and easily goes over 8k, so anything that provides more information than a traditional steam gage used in parallel with these could be a breakthrough in terms of quality at low cost.
So the final question is which more reliable are these dedicated avionics in relation to these new wifi alternatives that use tablet as a display? I think few people can answer because is hard to find reviews.
