Would be fun to see what happens if you have two of them going after each other…
If people have never seen them drone battles are a real thing, go to youtube or RCGroups and search for FPV videos of “war quads” to see what it’s all about.
A little to $$$ intensive part of the hobby for me to try.
Interesting concept. Being able to run fairly high performance machine vision & etc onboard due to the short flight time needed for an intercept… nice.
Dangling a string down is all well and good for going after a statically hovering drone…but drones do tend to move around. Get’s real tricky to dangle string precisely when high speed wind is involved I’d imagine. Just keep your drone on the move to avoid this sucker. 
Why not just build a tough drone with protected rotors and have it aim to knock the other one out of the sky.
Searching War quads on youtube just finds me people on quad bikes having a laugh. Is there such a thing as a Robot Drone Wars tv show yet?
In any case I’m sure the FAA are rubbing their hands at the thought of heavily regulating the industry once drones start dropping from the skies as partially disabled whirling blade storms, yay…
I think the dangling string / chain / whatever will be effective. With accurate position tracking, enough agility, and a decent algorithm… it’s only got to be over top of the other quad once to take it down. An extremely fast/quick multirotor with a 2min flight time should be able to handle this job. High discharge batteries may be the largeset limiting factor.
Just stick an umbrella on the attacking drone, simples.
Come on Wight, we can be the first on the market with a Rapere proof (ie “dangle proof”) drone! 
these is great! (and expensive, sure!)
found it searching for fpv wars, as mentioned above
Makes me think of Ben Hur, “ramming speed”.
So epic!
The quads in that video are not your typical fighting quads (I dont know why there are so few video’s of actual quad wars on YT, maybe it’s illegal or something, theres videos all over RCG). Each of those cost, atleast $1000 for those setups (plus controller and video viewer plus batteries and spare parts), VERY expensive crashes to say the least lol. Those all have 5.8Ghz video (for live HD video output, that’s what the big 360* antennas are), tons of radio gear for 2-way comms and telemetry and other accessories like camera gimbals, your typical war quad is 250 class, as light as possible and usually have low quality video, just enough to be able to fly them and no add-ons, definitely not for shooting high speed HD video like that. They’re also typically armored with foam padding and (depending on rules of that match) may or may not have prop guards. Wars take place out in the open and up high enough to try to have time to recover from a fall if nothing is really damaged. The goal is very simply to be the last one flying, demo derby style!
Come to think of it, the vast majority of the videos of wars I’ve see are either at night or in locations not ID’able and usually make sure to not show any of the operators, I’m thinking it’s probably frowned on, if not straight illegal, by the FAA which is why I’m not finding them on YT.
That video reminded me a lot of Wipeout 2097 on the PS1. :bigsmile:
Cool video! This discussion kinda reminds me of this other one I saw a few years ago (among others).
That video in Post 6 is so fricken cool. Big screen it for best effect. I need to get into this FPV thing.
Rc is a few classes expensiver. Be ready to start selling flashlights
^ Yeah. Since most of mine are not high end, a lot of flashlights.
This looks so incredibly fun, I agree!
And I dunno, but those little racing quads seem pretty tough and barring a few broken props they can probably take a hard knock or two.
Sure there’s relatively expensive electronics on board making up front costs high and there’s always a risk of putting those components out of commission in a crash. But I’m used to flying more traditional rc helis and there ANY contact between heli and ground is going to result in a fairly hefty repair bill and bench time to get it back in the air. Its usually the maintenance and repair costs that outstrip the acquisition investment on these things.
Who’s going to stick an array of white high power LEDs on the front of one of these and do a spot of night time FPV racing? 
A much better drone killer:
(for some reason, I couldn’t directly insert the video)
Punt gun for the win.
An envio-mentally way of killing drone?
A dutch company announced that it has been training eagles to knock down drones.
