The Flying Hexacopter UAV drone to 1 passenger and less than 10 000 €! DIY!

In these days, and especially the one he does, the bathtub is not such an absurd idea!

[Christophe]

Not understood the joke ...

[Ahmed]

For the landing in flooded area, it seems to me a good formula.

[Christophe]

Ah ... ok actually I was expecting something less down to earth from you

All France is more or less in flood since 1 month but now that it comes to Paris, we talk more ... inevitably ...

Here it's still drought

[Christophe]

Sorry I should have specified the North half ...

I also thought of a trick when I saw him take off, until the guy moves his head, if it's a fake, it's very well done.

6 rotors, it is certainly better than 4 but if a motor or controller loose it may still be funny.
In case of failure on a rotor, it is necessary that others can provide enough thrust to land smoothly while offsetting the imbalance, 2 rotors more seem essential.

[Christophe]

We just debunked the thing so stop talking about "fake" again ... that would be good

A brushless is 10 000h of life (compare to your car engine 5 000h ...) so the failure will come from something other than the engine itself ... a DHW or batteries.

On this prototype it looks like there are 3 batteries on each axis so 1 battery for 2 propellers, so no "central" battery.
In view of the total volume, there is about 1 kWh stored ... can be 0.8 can be 1.2 ...

The multiplication of the rotor is not necessarily an asset in terms of safety!

It all depends on how we see it:

a) There is more chance that there is a breakdown when there is 8 element than 6 and 4 ...

b) Does the failure of an element lead to destruction of the aircraft (concept of fail safe)?

A quadrotor that loses a propeller is lost, a hex and octo I do not know ... but it should be easy to check on the internet ... do some research on Youtube ...

If the hexa is fail safe in 5 propellers then it is this configuration that must be remembered (the ehang: Transportation-electric / l-ehang-184-first-drone-to-man-t14437.html 4 has a dual rotor so 8 engines ... although 8 single rotor would have given better aeronautical result)

[chatelot16]

a real helicopter can fail the engine without danger ... the blades continue to turn like gliders and the pilot can continue to master his craft ... it's called the auto-rotation, that makes part of the normal training of helicopter pilots

a quadricoptere is impossible to fly with a broken rotor falls in bulk

with a larger number of rotor there must be better tolerance to a failure, not that 6 is sufficient

but even if a large number of rotor makes it possible to tolerate the failure of a rotor it does not allow to go down in autorotation in case of empty battery ... empty battery = uncontrollable fall

the propeller has not fixed is a simple solution for toy or drone more advanced but without passenger, and weight low enough not to have a problem of security

if there is a passenger it is in my opinion mandatory to have helix variable not to master the descent without energy ... the simplicity of the drone has more helix is ​​useless if we put variable steps, so the true helicopter remains in my opinion the best solution ... there are very small helicopter

Good friends, a hexacopter with a ripped engine is indeed fail safe, answer found on video in 2 seconds on youtube:
