"1. Actually it doesn't cost me too much time to write the questions and read the other people's answers. When I ask same questions in different forum, I just copy them. I also asks these questions to my friends but I'd like to hear about more…"

"'Using' and tune Pixhawk/APM is quite essential if I want it to perform well. What knowledge or background it needs besides extensive experience on it?"

"Do we also need an engineer with theoretical knowledge in both flight control theory and flight mechanics? There are aerodynamics and flight mechanics engineers in our team. But we don't have an 'flight control engineer'. Does 'use' Pixhawk for my…"

"Does that mean it is quite hard(impossible?) to obtain a more accurate air speed with airspeed sensor costing less than 500 USD?

By the way how could it use gps data to obtain a more accurate airspeed? Wind changes all the time. Theoretically there…"

"Hi Andre,
Is there any book or document teaching the engineering process to get, as you said, ‘fully tested, documented setup, description how different limits are handled, air test, documented flight envelope for your UAV with a certain payload’?…"

"I don’t understand why the flight speed is limited by the auto spray trigger. If it doesn’t spray fast enough, why not use a stronger pump?"

"I can find hobbyist to teach me how to connect the cables and use Pixhawk.
What I want to figure out is whether we need a people with a university degree (master in autopilot?) or experiences to work for 'adapting' and improving Pixhawk on our…"

"Thanks for your reply and advice, Darrell.
 
Here is our situation. We are a startup and have no people working on autopilot currently. None of us has background in autopilot. We are aerodynamics, structural design and manufacturing people. You know…"

"I don’t get your point. Why I shall see some differences between these two boards if the only major difference is the quality control?
 
I haven’t flied the Pixhawk a lot yet. I just bought two Pixhawk as stated above. The main problems I got are:…"

"I have two Pixhawk board, one from 3DR and another one from a Chinese factory (we may call this 'pirate' one). The 3DR one has shown non better performance or stability than the 'pirate' one up to now from my experience. I have one 3DR 6H GPS, one…"

"Hi Gustav,
 
I'm interested in using it in the commercial UAV we designed.
 
I start to learn and use Pixhawk recently. I found that it was not very stable when I tried to connect it to my computer. The software Mission Planner and QGC usually…"
