"Hey Paul! don't sweat the old post. Yes I think that's been done' but assuming you have a square frame I don't think its worth it. Plus the props up above will cause more turbulent flow over the props underneath - causing reduced efficiency, more…"

"James that's decent but you would have to consider the intertia of the PVC rods and that the distance ahead of the front axle would tend to make them wobble quite a lot at high speed. possibly causing triggering accidentally.

"There is basically a prohibitive amount of liability in releasing a commercial product like this. Kinze and John Deere both have the technology for stuff like this. There's a Kinze autonomous grain cart on the youtubes somewhere, and John Deere has…"

"I'm not too surprised that people were afraid of it, but I am surprised they were afraid enough to want to stay in their vehicles. Especially guys who know tractors. Maybe they too recently watched the movie kill dozer? Or maximum overdrive? I've…"

"I saw earlier in the thread that you guys were talking about a servo controlling the steering by moving the wheel, and I can see how useful this could be (for example on our older tractors  which don't have very convenient steering systems to…"

"I'd love to offer whatever I can to the project. We don't have any combines here but I can see this being awesome for something like raking hay, where you're normally mindlessly driving for up to 4+ hours back and forth without stopping. This would…"

"After I submitted my previous essay of a comment I had another couple thoughts, but I decided to put them separate instead of editing.

"Alright so I've been reading this for a while now Matthew, and I'm only on page 8 so far, where you're discussing safety and redundancy. I think you've come very far since where you started, but you're missing a couple things. Some big, some small.…"

Andrew Crews replied to Michal Rus's discussion Quadcopter with down facing motors/props
"Hey if you hadn't thought of it already, having upside down motors actually gives you a tiny bit more safety in that, if you lose the C-clip that holds the motor shaft in, the prop will not pull the shaft out. In fact, I believe you can fly without…"
