I think you've made some very valid points Symo !
I have seen some racing quads with doubled up arms to make them stronger and I gues it would help a bit in toughening them up
Impact energy is linear in proportion to weight and and squared in relation to speed
So if it weighs half as much there should be half as much energy to do damage in a crash and if it's going twice as fast there is four times as much energy available to do damage.
Having said that 250 sized multi rotors are very forgiving in a crash, mostly you just break props, you really have to have a doozy to break a frame. I ran over my Qav 250 with my Yaris and the frame is still good!! It did bend a few of the screws that hold it together, broke the antennas and the props too
I had a look at a bolt 180 frame yesterday and it looked really strong it was flying pretty hard too. I'm not sure what it cost but it looked to be a fairly high end little machine. I'd have a look at one of those. I should have a little 250 plug and fly from Mongol gear next week to set up for a friend so I'll post a few pics of that when it arrives. Should be a fun little beast
