what kind of an engine are you using

[swisscaching]

No engine, only roket blade tip

A ROCKET powered single-seat helicopter was launched today at Oshkosh...

DF1 Test: -3 Celsius (Dust from the rockets is steam until the rockets burn after several seconds 100% of the H2O2).

Thank you for your comment, I'll take the time to answer these next few days ....

you're stupid, if you don't believe in science. i bet you're on the other team. how is it called? god?! fuck it.

[moneyman10k]

this is the most rinky dink piece of awesome shit i ever seen

[jcims]

@everett270 There would still be a small amount of torque due to bearing friction at the hub. Not much though, which is why the rotor can be so close to the pilot and not spin very fast.

[Downfacingdog]

stolen idea from Gilbert Magill in 1954

[everett270]

There is no torque caused by the rotor, the tail rotor acts only as a rudder.

[Ibringthetruth1]

is the fuselage made of wood?

[GreenAce92]

why is there still a tail rotor? Because there isn't a rudder?

[GreenAce92]

@jimday666 hahaha god flies without rotors

[JetBeetlePropulsion]

How long could you stay airborn ? and what's the fule consumption ?

[Zooni2]

Germany was using this technology in WW2. It's incredible and interesting. I thought the design made no torque, but the tail rotor on this copter means that's not the case.

[BrohnsProductions]

absolutely amazing!!!! didn't think you were going to take off initially

[birchyboy01]

On second thoughts - blade tip propulsion = no torque! Hover rotation by rotor shaft clutch?  I've got to get one ...
