so-cal, that wasn't directly at your rail comment, it was at airframes and motor counts in general
I engineer uav and test more gear in a month than most people see in a lifetime.... I drive 2 hours each way just to get in the wind 3-4 days a week, i'll disagree with your disagreement based on my observations
there is virtualy no difference from the number of motors. it's strictly the size and the amount of thrust compared to it's weight..... start putting too much weight they all suck, that is a 550 with anything bigger than a hero zen, she becomes overloaded and is a pig in the wind... quad is easy to tote around, hex becomes a baby seat in the car, a octo becomes the size of a couple people... i can fly my 5 lbs disco in wind with better results than i can my 32 lbs octos,,,,, bar none, day in and day out.....
For the most part, it's true. Assuming not carrying anything, and thrust/weight optimized on all platforms, the hex and the octos form a larger "platform" of thrust, a disk, if you will. All things being equal, It takes more external input to 'tilt' that larger disk then it does the smaller disk. That is basic Newtonian physics. And the tilting of the larger disks tend to be slower than the smaller disk with the same amount of external input. Clearly, there is a big difference flying a Quad carrying a GoPro vs. a Hex or Octo carrying a much heavier camera so its really comparing apples to oranges. That's why I said, as a general rule, a Hex or Octo in wind would be more stable. I also mentioned that it has a lot to do with the FC as well. Anyway, that's my story and I'm sticking to it. :tennis: There's nothing wrong with agreeing to disagree.
