HERE YOU CAN SEE SOME OF THE TECHNICAL INFO AND ECONOMICS

The technology today is moving quite fast allowing the technical possibility of this aircraft. High efficiency brushless motors with good output are available nowadays. Programmable motor control systems combined with gyroscopes allow maximized  safety. With modern application of GPS technology these systems are opening possibilities for further development. One of the most important area is a further battery development that will allow expending the flight envelope. The existing LiPo technology has now been combined with nanotechnology allowing the performance of the batteries to be improved not only in the energy per kg, but also in the power per kg. For a 5 min flight one still needs a considerable battery pack, but it can be done.

If we reflect on this development, it is basically the RC community that demanded specialized products with top of the bill specifications. As the RC planes and helicopters got bigger, the equipment evolved simultaneously. Imagine a 10 KW electric motor weighting 2.5 kg. Quite a feat!

With the use of dedicated aircraft materials like rotors and e motors, the costs of the prototype craft are substantial in today’s value and amount ca 200.000 Eur, of which 50% is material and 50% is workmanship. Both can be reduced considerably in future if produced in series.  A target could be 150.000 Euro/craft.

 The aircraft brushless  motors have low losses and no wear, and LiPo technology, based on the high value,  provides the possibility for recycling. Noise is limited to the propellers  since the electric motors are quiet. Due to these facts we can say that aircraft is environmentally friendl
A range extender can make the craft fly one hour and come close to normal fuel based helicopters.
