That is true for HYBRiX, but there are other hybrid multirotors, which do not have a design well-balanced enough to being able to stay aloft on just batteries (batteries to lift a 25kg MTOW drone are heavy, so the drone needs to be very lig

Equivalent hydrogen multirotors at this stage do not have the payload capacity of a hybrid fuel-electric drone. They might be a great solution in the future, but the technology is not there yet.

Sorry about that! :(

It's because of the duty cycle of the engine, we put it at a constant rate of 12000 RPM for hours. It is not the standard setting for that engine.

Yes, it is a series hybrid, the engine acts as a range-extender. The mechanics of the aircraft are much simpler this way and therefore more reliable. We are not sure about the efficiency, though. There are no helicopters under 25kg MTOW wit

Of course it does not compare to electric multirotors in that aspect, but its performance is much more advanced. We aim to replace combustion manned helicopters in first response applications, among others. HYBRiX can provide similar operat

A hybrid drone like HYBRiX has power redundancy. If the engine stops for some reason, it still has some minutes of endurance in electric-only mode, for an emergency landing. With an unmanned helicopter, if the engine fails, the crash is mos

Fix wings are amazing for some applications. The problem with them starts when you want to carry heavier payloads. Taking-off and landing gets more and more complicated as they scale-up, while you only need 10 sq. meters to take-off HYBRiX

The problem with that is that, in the end, you are carrying a multirotor on your plane. It is not so efficient as a fix-wing or plane and it does not perform like a multirotor, because it lacks hovering endurance. That convertible concept d

That's the point. Even though some fix-wings or convertible drones are able to do certain maneuvers similar to multirotors, their endurance is extremely limited then. A hybrid copter like HYBRiX is able to hover for hours, but it would

Quadcopters are equivalent to helicopters in terms of performance. VTOL-planes fly as a plane, they do not have hovering endurance, barely a few minutes at the most, just for take off and landing. So they cannot perform missions that requir

The main reason is that multirotors are a much more recent solution, and they started as small unmanned vehicles because the regulation is much simpler (the requirements for airworthiness certification for multirotors are not standardized y

Hi all! thanks for sharing the news! At Quaternium we are very excited to see that our project is raising so much interest! There are already many accurate comments on this thread. But just to give you some context. Quaternium was the firs
