Although I definitely would have guessed that the octo would lift more, it's good to see this kind of experiment being performed! Don't trust your intuition, it's frequently wrong, go out and test, while recording. It's good for you and good for the world.
I thought it was unfair to weigh the X8 down. It already has the handicap of 4 props going through "dirty" air so matching the weights of the 2 drones was like taking away the advantage of the X8 but not giving its disadvantage to the octo. I think the octo would've still won but it might have been better matched.
A lot of people commenting on the added weight to the x8 being unfair, but the benefit of an octo is the ability to throw larger props which they didn't do. In their test they effectively handy capped both drones by matching weights and prop sizes. In the context of the "matched" thrust test I can see why they did it. What they should have then tried is a test in "best" configuration. So the x8 gets its light weight benefit, but the Octo frame gets to use bigger props to maximise its thrust to weight ratio.
the x8 was just a converted fpv drone, if they extended the arms to have the same length as the octo the x8 could get massive props, but because they were so close together in the vid the x8 wasn't optimal
Why did you put the extra weight on the x8? From a scientific point of view that was the wrong thing to do. You can't compare two different designs by nullifying design features. A bonus if an x8 is it weighs less. Its a trade off between size convenience, thrust and weight. Could you redo this without stacking the odds against the x8? It still won't lift as much but it should outfly it.
well they technically they tested 4 vs 8 propstreams and with the weight being equal my guess is that the props stacking is canceling out or at least greatly reducing the power those props can put out this is further shown in the X8 where its way earlier at max throttle since half the props put out almost no lift there. this is also seen in biplanes wikipedia qoute: In a biplane aircraft, two wings are placed one above the other. Each provides part of the lift, although they are not able to produce twice as much lift as a single wing of similar size and shape because the upper and the lower are working on nearly the same portion of the atmosphere and thus interfere with each other's behaviour. In a biplane configuration with no stagger from the upper wing to the lower wing, the lift coefficient is reduced by 10 to 15 percent compared to that of a monoplane using the same airfoil and aspect ratio[1]
for pulling im fine with the weight since they were testing if you are losing power doing motors on top of eachother.. but for freestyle and tug of war they should of removed the weight.. though it would of still lost tug of war
Great comparison video, if I were there I'd have suggested speed runs to see which is fastest, with and without the additional weight to the X8 to see what difference it made.
If you want to make the X8 more efficient, you should put a steeper pitched prop on the bottom motor. With the air already being accelerated/dirty, a prop of the same pitch won't produce as much thrust on the bottom, but a greater pitched prop should increase performance
I love all your videos. Would have been cool to see a view of the octo flipping from ground point of view. So fun, keep up the good work. I had a DjI s1000 in 2014 and would never thought it could flip! Cheers
We’ve seen a 30% reduction in efficiency on the four motors that are reversed. We’ve actually been able to calculate the curve and it seems to hold true on various size multi rotors.
Chris Rosser said that kinda thing would happen. So much current it'll de-solder itself. What a hobby: self de-soldering power pigtails and a small risk of burning your house down every time you charge batteries. Love it!
Lol, you can just see the worried expression on Shawn's face! Also, cool video idea, the rotor riot guys should make a quad with nitro engines instead of motors. Like the comment if you want them to to see it and do it.

I found this interesting because I have 3 x8 drones from 3dr. I got them for basically nothing when they was selling everything off a few years ago. I bought a case of motors for something like $2 each
Simple aerodynamics. Bigger unobstructed prop area means more thrust. With the x8 configuration, you get efficiency loss with the counter rotating blades.
I love this style of video. Do it again without the handicap of the extra LIPO for weight. Each style of 8 seems to have a benefit: more lift or less weight. But you cancelled out one of the benefits.
In the test results, it didn’t matter. Add the 1.1lbs weight to the calculation and the. Octo still killed the x8. Also, we removed the ballast for the tug of war
It's not so much about the dirty air. It's more that the x8 has the same prop area as a quad where as the octo has double the prop / surface area of air to push against.
While this was a fun video, I would have liked to see a little more discussed about the two platforms that are very very different. For one thing, the two don't even have remotely similar prop sizes. There's also a pretty wide spread of performance with cinelifter X8 crafts too...
Test how it responds to a motor failure. Seems a benefit to an X8 with a redundant motor could help you get home if 1 motor went down. Also an X8 and how much real thrust is gained versus a regular quad. Also taggering prop pitch so bottom props are not stalling out. Maybe next comparing something an octo with 8 motors and 5in props might need to compare total thrust ouput to something like a regular quad with say 4 8 inch props in same thrust range.
Is this new Info?!??! We did thi shit in 2009 when we were testing Freely Cinestar 8's (octo's) vs Hexacrafter X8's. I can't believe this even gets a view.
Don't ask why we had to test this, but my 5" freestyle quad with 5.5" props can lift a gallon milk jug that is a little over half full. Six pounds. It was hovering at something like 80% throttle.
@@creationlabsinc.189 We had a 6 pound 3D print that we "had" to lift. We tried to lift the entire gallon with someone's old 450 flamewheel build. It had 9.5" props and 2212 motors, and was meant to be run on 3S. We tried all the way up to a 6S pack, and it couldn't lift the whole gallon. It couldn't lift the ~6 pounds, either. By the time I said, "Let's just see if my regular quad can do it!" we had already spilled the extra 2 pounds on the ground. It was not a good flight, but I had lift, and I could have kept flying. ;)
Radial setup is 20% more efficient than coaxial. The latter is an addition to make a more portable solution, more powerful. A radial drone is bulkier and more powerful but less agile. If by any means, one can attach a gimbal on the lower side of an X8, I don't see the benefits then of a radial octocopter beyond the lift strength.
Build an x8 with a bit longer arms and put the down motors more inwards and some landing legs below the upper motors (that are on the outer end of the arms) So you have only 4 arms (lower weight) but prop area like the octo... And no prop has dirty air
Adding extra weight to X8 does not make any sense. It already carries extra weight for this shape - that’s why it can’t lift additional weight as octocopter without extra load.
I don’t understand why the battery was added to the X8 to make the weights the same, one of the advantages for doing a stacked motor setup like that is for less weight contrary to an octocopter because less frame, so one of its advantages from an octocopter is just removed for these tests, I don’t think it would’ve affected the weight lifting and the tug of war, but the handling test with how it felt “heavy” probably would have been judged differently
the x8 would perform better if the bottom propellers had slightly more pitch because the air is already moving so to maintain angle of attack more pitch is necessary
I would be interested if a quad with, say, Xing 2806,5 and 7" props outpower an octo with 2207 5". I bet it does which would make 5" octos kind of a silly setup.
That´s not true for "real" octos or hexas. Each motor has to lift less so it´s ampdraw is lower. Anyway it´s a lame video, we all did this already, back in 2011.

ya... but try and use them how they really would be used. ie, without the extra weight on the x8. thats the whole point of the x8, its lighter and smaller.
The ballast doesn't make any sense. Imagine a car review where they added weight to all the cars until they weighed the same before comparing them. If one design has a weight advantage, and the goal is to see which can lift more, why would you decide to equalize that advantage then compare them?
100% obvious result , X8s lower motors run in dirty air and lose around 30-40% thrust as a result , a way around that is to run Higher pitch or Longer Props on the lower motors, even then 8X is still inefficient compared to a Octo, on average an X8 would be about the same as a Hexa config in terms of power .
Why string the weights...try separate amounts lift out of ground hover hold for 10s then land and add weight. Too much pendulum effect w the weight configuration ur trying
for the freestyle and tug of war should of removed the extra weight.. the 1lbs weight saving and smaller size would be the reason to go with x8 over octo
4s is what the motors can handle on 7” props, and xt60 doesn’t usually cause a problem. Only when you are trying to make a quad full throttle while stationary. 😂
@@LetsFlyRC well yes but why wouldn't you use lower kv motors on 6s with an xt90 at least, a 5 inch kwad can push an xt60 to it's limit sometimes and I melted one myself on my own 5 inch. Using on on an octo with that prop size is just impractical and begging for disaster.
