1.I meant weapons whose projectiles are affected by gravity. As in, they drop. It's minor, but it certainly has an effect at range. Also, recoil is primarily vertical, so automatic weapons are less effective against a wide target.
2.Uh, a horse just isn't faster than a helicopter. Of any form. And it isn't as reliably fast- a horse will slow down in heavy brush or rubble. As far as flying in bad winds, it's capable of accurately firing a weapon in near hurricane force winds. Why would we be fighting in a hurricane?
3.Honestly, I wouldn't put nearly as many guns on one. I'd probably just put a single laser on it, cutting if possible. That could easily be an electrolaser, considering that they're barely larger. Actually, I just got a wonderful idea. See bottom of post.
4.Umm, no. I'm saying that it's easy to damage it with lasers. You would have to armor it against those. It's not immune to gauss weapons, it's just hard to hit it with one, because it's a small target that's moving fast. If you did hit it with one, it would probably go down from a single shot. And I'm saying it's even harder to shoot it with rockets, because rockets are slow and it's still a small target. If you had homing missiles that could track it, those would easily take it out, but we have never seen any homing UWM weapons (Aside from LESHO rounds), and most homing weapons are thermal anyways.
5.Two is normal, because it's efficient. The 5% is accounting for both of them. How big is what?
6.That engine is dead. On a quadcopter, it can still fly, but it will be limited with what movements it can make. On a hexacopter, which is probably best, it won't be too affected by one engine loss, and it could handle losing two, or even three if they're spaced evenly around. Note that the engine is a cylinder the diameter of an apple and only an inch tall, and that's with archaic RL tech.
7.Yes, including the props. That's why I originally said it would have trouble being downsized enough to fit through doors- it would be bad if it has to follow squads closely through buildings, although it would excel as external support in urban environments.
I've been quoting numbers from the hobbyist assuming this thing is supposed to carry about a hundred pounds, split between armor, weapons, and power supply. It would weigh twenty pounds aside from that. He says a hexacopter with the listed statistics would end up being able to go at least 100 MPH, probably closer to 125, with a full load. He increased the size of it to 60" bladetip to bladetip though. The central thing would literally just be the size of the power supply and whatever weapons you have. If you increase the width of the blades, it would be more efficient, so it can carry more armor/weapons/whatever.
And he says he could easily build it with today's technology, EXCEPT for a power source. It would require a massive energy draw- not much compared to a laser, but a lot compared to what we can make in RL.
Get scout eye. Get cutting laser. Fly scout eye around corner, video enemies. Shoot through walls.
