Ah! Great vid. I'm fully in agreance with the turbo electric concept. Much better BTU than batteries. Now I wish i can get a unit like this for my progects.....
Very impressive design, as we know, kerosene has a lot of BTUs per KG, and the turbine is also light weight. you should have range and 'hover on station' advantages over the electrics by a huge factor. Payload could be hefty too :-) Far more than toy potential. Thank you for sharing.People should read about Quad Rotor control before commenting on the shortcomings of your design..
If you stopped the front props it will tilt you only ever need a tilt of about 30 degrees, any more and it would be difficult to control. The props are on electric motors so they can be controlled precisely. Variable pitch is only used to compensate for having one lifting propeller which is the case on a Helicopter.
5 stars! Much more difficult than most might think. Have you thought about individual variable pitch similar to a tail rotor on a heli for each of the four blades to control flight direction? Beautiful machine. Mike D
@m1leswilliams How would you do that? It is much faster to change the pitch using gyros and servos to push/pull an arm that change the pitch from POS/NEG for the split second it is needed. Please explain how you would alter the propeller speeds for the split second it is needed to stay level. I look forward to your answer.
Not very stable, but really cool. Nice job!!!!

@vdog1997 nothing is stable in ground effect.

Quick question about the blades, What is the profile that you are using to carry such a load?

This is funny, can not imagine why someone would build it. And ohh, it would probably fly higher once you cut the ropes!;0)

why a turboshaft-electric drive ?
is that really more efficient than all electric ?

how exactly do you transer the power from the turbine to the propellers? Can i see some schematics please?

@TiagoTiagoT did you pay him to ask him for his schematics on his work? get a life

@rodstartube i mean some simplified drawing of how it is done, not the classified master plans

First I agree with this "did you pay him to ask him for his schematics on his work? get a life"
Second, don't you see the torsion rodes bellow each propeller chassis arm?

@mdivinc Variable pitch isn't needed, all controls are possible by slowing and speeding up the 4 props.

Much more difficult to stabalize with a single power plant. I like alot.

HA HA never hear u coming with that thing lol
austinpowers1977 2 years ago
so cool, do u need a stabilization program for this kind of design. like a little microcontroller to keep it stable??

how is a turbine spinning the props?
robotmanx2009 3 years ago
All turbine to mechanical movement is done with a blow by concept, rarely is there a physical connection directly to turbine.
