Thunder Tiger Shows Off a Fuel-Cell Heli

Thunder Tiger recently showed a video of a new helicopter called the HXC2 Jupiter. It's a hydrogen fuel-cell powered coaxial helicopter that will be amazing for long flight times. It has a 6000W fuel cell module which can be seen on the outside with carbon fiber cylinders that are filled with hydrogen.

They say the flight time is 3 times that of a conventional drone and can carry a greater payload. That translates to hours of flight time carrying an array of sensors and data capturing equipment. It is the world's only fuel-cell powered coaxial helicopter. Other specs are light at the moment, but more details should be available once Thunder Tiger Robotix puts up the webpage for it.

Im interested in seeing it move about. Would like to see if it suffers from the pendulum effect like the old blade cx

this is nothing like the coaxial counter rotators that were common in the hobby about 10 years ago. Those used a self stabilizing flybar arrangement on the top rotor, hobby grade coaxials often had a lower rotor blade swash plate. this new helicopter is akin to the Kamov helicopters from Russia. These have both a lower and upper swashplate. Full scale use a pushrod in the center of the main shaft to control the differential pitch required to cause yaw, this model may just utilize differential speed with independent motors for yaw, but it does have a top rotor system with a full swashplate, so it should not suffer any of the pendulem effects you are mentioning.

here is a model proving coaxials aren't all the same
Coaxial 3D 550/600 twin motor (4 min 24 sec)

It looks to me like it has a pushrod going through the center of the main shaft for differential pitch for yaw, as indicated by the mixing assembly above the upper rotor head. If that is true it gets the odd and complicating resultant reversing yaw phenomenon that all bicopter helicopters experience, when you use differential pitch for yaw, it flips on you with negative pitch.

last time I saw a big outdoor collective pitch coax, it never made it to production. I was interested in this thing https://www.rcgroups.com/forums/show...g-to-market%21
