short burst of thrust for quadcopter... is electric a possibility?
My end goal here is to have a quadcopter that will be able to dodge projectiles with incredible speed (without having to wait for the propellers to rev up). I need a thruster that wouldn't necessarily have to emit a constant thrust, but I do need a good burst. The module has to be extremely lightweight, as it will be on-board the drone, so I'm wondering if there's some method that can convert electricity into directable kinetic energy. To get the burst I'm thinking something along the lines of a capacitor? This would need to charge up, but would also emit a lot of electricity when it's released. Thoughts? (oh, and also I'm only a teenager and hardly have anything of a budget, so it'd be nice if I could get a relatively cheap option. However, even if it's expensive I'd still like to know if it exists!) Thanks in advance!
