The PX4 is here and soon it will have a fully supported version of ArduCopter:

From what I have been able to glean, Chris and Company are now in the process of revising this controller for better use by our group including an enclosure.

I Do not know for sure if they are planning on modifying the board itself but indications are that they are.

Now this is completely unsolicited by DIYDrones and may even be an annoyance to them, but there are some things I would like to see in there and I'll bet some of you would as well, so now is your chance to sound off before it becomes a fete acompli. 

Whether it will do any good or not I haven't got a clue.

An enclosure is good, but a internally vibration damped enclosure that was truly effective for reducing Accel vibrations to a fully tolerable level would be great.

Also, the existing PX4 pretty much requires that you use a PPM-Sum receiver with it.

PPM-Sum receivers are great, but only a few are available (Futaba and FR-Sky) not counting Graupner for obvious $$$$ reasons.

Personally I would like to use my plain old vanilla Hitec Aurora 9 and I think a lot of people would be a bit put off by having to upgrade their whole radio system because they didn't want to include a few extra RC inputs.

That's the 2 biggies I can think of, this is the place to put in your thoughts and we can see if anyone is listening.

This feedback is certainly unsolicited, I hope it is not also unwelcome.

I would have thought it might be better to have your say on the PX4 group itself. Its a more advanced controller so I don't think it should be hampered by support for legacy equipment. Other receivers are mentioned here!topic/px4users/Gj9sRy... and looking at this video I think your gear should be supported.

Oh wow I want the racing car and I want it now.

Wish she would do more voiceovers.

How about a static port over the barometer?

Actually, I am trying to fly PX4FMU by PX4 autopilot. However, there is an issue of PPM-Sum receiver for the  compatibility by the model and the manufacture of R/C equipment. There is communication issue on FASST S.BUS mode of Futaba and FR-Sky TFR8.  TFR4B can communicates with PX4FMU. A you know, Futaba also submit S.BUS2 in the market.  So, I prefer embedded PPM Encoder v2.0 on PX4.

I have a beef with the AIO controllers. In an ideal world, the processor and wire interface would be one unit, that you can hide somewhere in your frame, alongside the r/c rx, telemetry, atto-sensor, osd and whatnot and for which you can't care less if it's exposed to vibrations or misaligned. Then there's the IMU - just a 5-wire strip of cable to care about, with some added mass and gel pads to dampen vibrations and then probably an off-board magnetometer that you can mount well away from the ESCs and the rest of the power-train.

this should solve your PPM Encoder issues:

Interesting to see how rapidly expanding in complexity the once simple task of an autopilot is becoming.  The Ardupilot code base had grown to 7MB.  Now everything is moving to PX4 which is 36MB.  The mavlink headers alone are over 210 files comprising 4MB of C, C++, & python.  All this to get the battery voltage to show up on an RC transmitter.  It's either many chefs trying to get their dish in the kitchen or an extreme pursuit of abstract, pedantic programming.

These days Jack I think that it's somewhere between growing complexity and I'd call it 'learning the hard way'

Funny you should mention that, been out flying my Atto equipped wing from back in the day. Chuck it, it flies the path based on where I took off then land by hand. To create imaging overlap walk 500m and repeat the exercise. No GCS just extra batteries and SD cards.

With so many modern TX/RX coming with built in data links why not just use them.

The generation after PX 4 might see simplicity and elegance return.
