Platform (both hardware and software stack).
What firmware version (bleeding edge, beta releases, last stable, or one stable behind)
Primary vehicle type/what other vehicles do they use?
Primary GCS used?
What platforms is the GCS run on (mobile/windows/linux/mac)
Use cases (multiple answer I would assume):
-(anything else others can think of)
How long have you been working with UAS/these projects?
How well do you feel that issues you encounter are addressed?
How well do you feel that you know what features are being worked on?
Some write in answers (which are hard to collect/post concisely)
Ease of use?
Areas of initial confusion? (The initial setup was very confusing when I first went through it, and I suspect I can't separate my current knowledge well enough to see how a new user would feel)
Number of crashes/fly aways and what caused them. (This tends to be user configuration error though, and some people just don't know so I'm not sure if the SnR is worth asking this)
If at all possible could we get the questions posted up here/peer reviewed before it goes out? The autopilot hardware surveys had a couple of things added after it was out/that were notably missing, and there were several very biased questions that made it hard to interpret the result.
