Einer der ersten Bodenläufe von unserem RotorSchmiede VA250 ultralight Prototypen. Es traten keine Probleme auf. Rotor- und Steuerungssystem funktionieren wie erwartet sehr gut. Der Motor befindet sich noch in der Einlaufphase. Zu sehende Schwingungen/Vibrationen entstehen hauptsächlich durch die Fesselung des Hubschraubers am Boden und somit geänderte Steifigkeitseigenschaften des Gesamtsystems.
One of the first ground runs of our RotorSchmiede VA250 ultralight prototype. No problems occured. The rotor- and control system are working fine, as expected. The engine is still in run-in phase. Visible oscillations and vibrations result from the fixation of the helicopter to the ground which changes the oscillation behaviour of the whole system.

Love coaxial's, this is a nice looking machine. You have done a great job with the VA115 too!

Thanks mate :)

Sieht echt gut aus, dieser grüne Grashüpfer!

@elouanlavaux1514 3 года назад

Looks like à good machine! But have you planed creating some derived version for the other countries? In France, the ultralight needs to have a MTOW < 500kg. In fact, can't you just limiting administrativement a new version at 500?

@RS-fr1je 3 года назад

Thanks for your comment. For other countries we will also try to certificate the VA250. To limit the weight to 500kg would be the easiest possibility I guess.

@@RS-fr1je Thanks for your response! How high are the estimated operating costs ?

@RS-fr1je 3 года назад

@@elouanlavaux1514 For VA115 we have about 100€ per hour including nearly everything (insurance, inspection, spare parts, fuel,... but no buying price). For VA250 we don't expect much more. Let's say an estimated operating cost of 125€ per hour.

So more than 3 years no update. Assume this is no more, failed project? Too bad, it looked very exciting.

Molto interessante. Il motore a 2 tempi di chi è? Si può saperne di piu?

@RS-fr1je 3 года назад

Hi, the actual installed engine won't be used for series production. We want to use another one but this topic is some kind of top secret. Sorry ;)

Isnt this supposed to go under the new eu ultralight weight category? Dont they have a simplified framework for certification? Wasnt that the point of the whole thing? Why is this priced like a regular helicopter at 150k? It doesnt look like its supposed to cost that much. Theres a swedish company producing a manned coaxial quadCopter under the same regulation that will be charging 60k euro for it. The stylish fraundorfer tensor is under similar simplified regulation and will cost 1/10th the price of this. Its a gyrocopter so simpler mechanics but otherwise comparable and were talking 10% the price of this. Even though coaxial rotor might be more complex doesnt the lack of tail rotor make the whole production process and maintenance a great deal more simplified? So what then is up with the astronomical prices for machines that doesnt look that more complex than a kawasaki? I get that they cant be as affordable as a sportsbike but come on, can you place the pricing somewhere around that area. Even half the price would be almost acceptable but 150k for a new rotorcraft under UL weight category is just grotesque

@RS-fr1je 3 года назад

I don't know it fits EU regulations. We will certify it for German ultralight heliopter specifications. After that, we'll try to get more certifications in different countries. EU regulations may be the same or similar. And yes, probably the framework for certiication is simplified but it's still a helicopter. Please show me regular helicopter at that price (new ones). I won't give detailed numbers of our costs and I won't compare to quadcopters or gyrocopters, but in order to understand the "high" price, you can make yourself a small overview. Just look at some aviation shops and sum up the prices for avionics and radio system. You'll get some thousand € only for this. Then an engine, a lot of machined parts, quite huge composite parts (which are handmade), aviation grade bolts and a lot of other standard parts, such as bearings. Quite all sports bikes are manufactured at a large-scale series production. You can't compare their costs to a relatively small series aviation production. Most of our assemblies are handmade which takes time and time is money.

@electricaviationchannelvid7863 3 года назад

It is a free market...you can set whatever price you want if there is demand you are going to sell...Sometimes you have to pay extra just for availability...I do not know any other Coaxial helicopter at this price range...so there is no competition. Furthermore to get to production scale and quantity is a huge investment of capital and time/resources...I congratulate RS for their effort!

@electricaviationchannelvid7863 3 года назад

A quad copter or alike VTOL has different aerodynamics and advantages/disadvantages in each use case scenarios from helicopters...their limitations in weather are also different...For certain applications the new VTOL/eVTOL designs will not replace helicopters for other areas they are going to disrupt the market...

@abvmoose87 3 года назад

Is it really not possible to make new rotorcrafts more affordable? 150k euro is just way out of reach for the common man. In terms of machinery is this really that more advanced and complex than a modern sportsbike that can be had brand new for 20k euros? Even with the maintenance and certificationa that drive up the price is 150k really where its at?

@RS-fr1je 3 года назад

150k is an estimated price because we still haven't finished the certification of the whole helicopter. After that, we'll get more detailed numbers. But please also consider, that flying in general isn't the common hobby of the common man. Additionally, helicopters may be the most expensive way of flying. I think 150k are quite low compared to other helicopters.

@@user-eu8ij8io5y Yes that was a test, especially fixed on the ground. And no, the blades are not too small ;) We have experience in calculation and design due to our certified single seat helicopter VA115. The VA250 will have the same good flight characteristics :) But we still need to carry out some ground tests before flying. It's not a Rotax engine.

@@user-eu8ij8io5y Thank you very much :) We use the Hirth F23 for our single seater VA115. The VA250 has another one but may change in future. Therefore for the time being, we don't say which type ;) We still need to carry out some structural and ground tests in order start flight testing. I think in summer you can see it flying :)
