A report on a visit to the factory in Austria and demonstration flight of the AC-10.
The love of Rotary wing flight is a common bond that draws us to this Forum from around the world, our fellow members, a diverse and fascinating group that bring with them an infinite variety of skills and life experiences to share. When Chris Kurz began telling us of an exciting new gyro being born in Austria we were interested, when we saw the pictures, a lot of us fell instantly in love.
I do not believe in fairies, or something for nothing, but I do believe in love at first sight, and of having a dream. In the thread he posted, the proposed new machine was super hot sizzling eye-candy. It set pulses racing and a host of Forum members drooling, but it’s aims… and estimated price tag left most with the feeling that it would simply be a dream to be filed alongside that unattainable film star, super car/plane/helicopter/billfish/deer/, or lottery win that will make all of the aforementioned possible.
But dreams can be attained as all of us know. With a goal, hard work, bit of luck, determination the human spirit can and does achieve some pretty impressive feats, we see them on the Forum all the time. Dietmar Fuchs was a gyro pilot who had flown Magnis and MT’s but had a dream that he could produce something better. Chris Kurz, another gyro pilot had a dream of flying across the US in a gyro true, then did so, enthralling us all here on the Forum as he took us with him, saw the ArrowCopter, and along with the rest of us, fell in love and promptly had another dream.
Dietmar Fuchs and a growing band of the converted, is sure that he has produced something better, the ArrowCopter; and Chris, by working with Dietmar and earning it with sweat equity, now has his own one. I am still dreaming, but do have a goal. After an invitation to visit the factory came, a date was set, and Chris with great generosity, offered to pick me up from the airport, put me up, and take me to the Factory. How good was that?
Having seen Chris in photos, posted on the Rotary Forum during his epic flight across the US in his MT-03, I managed to spot him when I walked out of arrivals, but what his photos hadn’t conveyed was how tall he is; so when I say he stood out in the crowd, he really did; head and shoulders above the rest. During the surprisingly long drive home, not just round the corner, it was rapidly evident that he is besides being a totally committed gyronut… sorry, gyronaut, he is warm humorous and multitalented. On arrival at his home in Eisenstadt I met a gracious and charming Katharina and one of their daughters, Salina, before immediately being whisked off out to dinner to nearby Rust. When Chris had told me that he lived in a good wine area, he wasn’t kidding, some of the Austrian wines he picked out during the meal were superb.
Early next morning Chris and I were on the road for the FD-Composites factory at Amstetten. As with a lot of us gyro folks, the factory and nearby airfield St. Georgen where they fly from, was a serious drive away, but with a lot to discuss the journey went pretty quickly. The factory is a neat compact two story structure set in countryside, and upon entering I was greeted by a sight made familiar by the website photos. A line of ArrowCopters in varying stages of completion. After meeting Dietmar and most of the staff, Chris, who was now acting as factory spokesman, began the tour and I was given permission to photograph anything I wanted.
The atmosphere there is of quiet calm, and people who know their business doing just that. As Chris took me along the assembly line I began to, as Chuck put it, ‘began to look under the pretty dress, glamor, and flim flam’, to see just what does go into making up the bones of the eye-catching craft this machine undoubtedly is. Without a big red S on the chest and lacking X-ray vision I was not able to stress analyze the various parts I was able to pick up and examine but every single one, was light, strong, and looked of uncompromising build quality. Carbon fiber parts look good if done well. I should know because I built the pod for our Hornet from it, parts of which did come out looking as good as the ones in the magazine pictures and glossy ads, but in the end Stu and I chose to paint it, because I wanted to hide those unfortunate blemishes that had occurred due to overheating during the cure and showed up like pimples on a supermodel’s face. A great deal of these machines is carbon fiber, and all I saw was done to a high standard.
The engine bay has a stainless steel firewall between it and the structure of the back cabin. After the firewall and rear cabin wall there is a shallow area that contains a lot of the wiring busses and sensor boxes, engine recorder and remote units for the MLG EFIS. There is a cover for that and then comes the seat back. The rear occupant is therefor well insulated and shielded from both engine and the noise. With the seats out panels in the floor allow access to wiring, fuel lines at the rear coming up from the fuel tanks in the stub wings and the large thick push pull aircraft grade cables that actuate movement of the rotor head. I know some people have expressed reservations however these a very thick aircraft grade assemblies and I having seen them would have no such apprehension. As we moved slowly along the line of fuselage sections starting from the unit least assembled I watched a whole nose wheel assembly removed in minutes for adjustments. A main wheel removed in minutes to disassemble and change a tire. In the nose section the instrument panel and all instruments were very accessible for removal or inspection.
Part way down the line I came across a Ferrari red model being worked on by a man and his two sons. On being introduced, his name and who he has been associated with rang immediate bells. Dr Claudius Klimt, and Carter Copters. I had noticed on arrival that Vienna is presently celebrating the 150th anniversary of a very famous 20th Century painter, Gustav Klimt, and as for Carter Copter, I think that almost every member of the forum is aware of who they are. Claudius's is an interesting person his career in emergency medicine included the creation and leadership of Charles Emergency Physicians P.A. providing emergency service to over 54,000 patients per year at the Greater Baltimore Medical Center, and his position of Vice Chief of Staff of the Greater Baltimore Medical Center. His attention to detail and team building led to the development of an emergency physician work scheduling software program with Peake Software, and he continues to practice emergency medicine on a part time basis. He served in the Maryland Air National Guard as clinic commander and flight surgeon of the 135th TAC Clinic and retired after 22 years as a Col. He has his SEL, SES, MEL and Instrument pilot ratings with over 2300 hours of P1 and has built a twin engine kit AirCam N119CK. His fascination with the Carter slowed rotor/compound technology had led to extensive volunteer contributions on the Carter Copter team to help bring the concept to production.
ArrowCopter has been forward-thinking in recognizing the present US impasse on factory built machines and is along with the factory built models, producing it in a kit form that will allow a builder to satisfy the 51% rule and build his own machine. Claudius was there working on doing just that. With one son videoing his every move the other was carefully documenting the process. Having had the pleasure I just loved the idea of a family team-working the project, it is hugely satisfying. They have a schedule and he is moving along at a brisk clip. Jay Carter is a genius and has a great concept, ArrowCopter has one too, and it is here and now, perhaps why Claudius is at the factory. His brand new, just delivered Rotax 912IS was sitting on the stand waiting to be installed and he is extremely enthusiastic about this machine. I have a feeling it won’t be long before that one is ready to take to the air. Oh and the name…well as it turned out when I asked, that yes he was connected to Gustav, but ‘on the other side of the blanket’ I think the expression goes. Gustav was never married but fathered 14 children and apparently, so Claudius says, pretty stingy about passing on the painting gene.
After a detailed tour of the factory and the avionics shop upstairs where avionics and instrument panels are prepared , we went over and looked at Chris’s machine which was in a separate hanger along with the rotor test car. This was an extensively altered BMW with a mast built into the roof. Heavily instrumented with the equipment that measures rotor performance the cyclic stick is in the passenger side. The level of detail they go to in testing and improving the various areas of the gyro is impressive. Chris’s gyro is fitted with the constant speed prop mechanism which he likes and is an upgrade on the in-flight variable propeller pitch adjustment on the machine I subsequently flew in.
Before leaving for the airfield we did a quick summing up. There are three test machines at the factory presently flying and working on the Austrian Certification (Austrian certification standards took UK Section T as a base, then added bits for good measure.) one is presently trial flying in Australia, and two are trialing in South Africa. One kit build in Switzerland is working on Swiss certification. There are five machines presently on the production line for customers, and, while I was there someone who collects unique airplanes was sending over his chief pilot to have a look and with already a huge collection of amazing machines it may just get bigger. It is intended that pre-certification machines and kits are designated AC-10, the next group after certification will be AC-20's.
Chris then took us down to the airfield where Dietmar was getting OE-VXI ready. The wind was across the runway, very light and variable with an OAT of 16 C and Dietmar did a solo flight first. He took of from the far end of the runway so it was not possible to see how much the take off run was used, however it was a very short time to lift off. The aircraft then kept just above the ground and built up speed. Dietmar reported 200 km/hr or 108 kts as he passed us before pulling up into a steep sustained climb. He then dived back down on a down wind before proceeding on to a number of low level turns around the far end of the runway demonstrating a very tight radius before another fast climb past us. At the top of which came a hover before proceeding into a vertical descent with a number of 360 degree rudder turns. This then evolved into a tight spiral dive and recovery onto a close left down wind. He then produced a very low slow flight down the runway before pulling up on a procedure turn round onto a final to land with a very short landing, almost in it’s own length, before turning off onto the taxiway. The radius of the turns had been very tight and the machine looked every bit as responsive agile as I had hoped it would be
Quick refuel followed, the position of the fueling ports making this the simplest and easiest I have ever seen. Getting into the back was very easy. Allowed to step onto the wing and seat it was a non event. The seat was very comfortable, it’s smooth contouring and position fitting one like a glove. With another pilot in the front seat visibility to the immediate front is not great, but up and from 45 degrees ahead to the sides and rear excellent with no canopy distortion at all. Provision will be made for a repeater screen for the MGL Voyager EFIS to be on the seat back ahead of the second occupant to present all instruments to the rear seater for instruction, or type check out. While in the certification program rear controls have been removed so just along for the ride. Start and taxiing all routine, ground handling seemed excellent with differential braking. Dietmar now took of from the opposite end which has about 200 m of asphalt before the grass.
Pre-rotation seemed quick with the rotor accelerating briskly before the button was released, the stick came back the throttle went forward and the brakes were released. A word on pre rotation on this machine: prerotation is only available with the stick fully forward. A safety switch mechanism at the bottom of the stick ensures that depression of the button will not result in anything unless contact has been made and within a certain forward stick range. With this satisfied button depression operates the two stage pneumatic system which begins first at low pressure. This causes a piston on the mast head to begin pushing up the drive gear into the teeth of the prerotator ring, at the same time through a second piston at the back of the engine beginning to applying pulley tensioning for the drive. When a proximity sensor on the gear ring on the rotor head signals full drive gear engagement, second stage high pneumatic pressure can then be applied to the tension on the pulley system and max torque applied.
Acceleration was very rapid taking me back to my first time flight in in a Lear where I was exposed to an immediate real response, instead of creeping off at first then gradually picking up speed. Almost immediately the nose was up, and we lifted off then leveled off to accelerate. Unable to see the ASI as I did not have a repeater screen, Chris gave me some figures he experiences in his machine. The nose lifts off at around 35 km/h or 14 kts, his lift-offs occurring at around 45-50 km/h, 24- 27 kts. He was observing the take off and estimated that we were airborne in approx 70-75 m or 230-250 ft, around half way down the 200 m of asphalt. That with a 340 kg/756 lbs craft, 23kg/51 lbs of fuel, 194 kg/431 lbs of pilots. ie we were 557 kg/1,238 lbs AUW. No headwind and 16 C. Pretty impressive in my book.
With the level off and acceleration my immediate thought was how quiet it was and with little or no wind rush noise at all, although looking out to the side I could see we were gaining speed at a rapid rate. Climb out was at a cruise climb angle and 800 ft/min. After a short while we leveled off powered back and began rotating the variable pitch knob. We were now at around 75% power, and 18Lts/4.8 galls/hr clipping along at a sedate 165Km/hr/ 89Kts. which would have put us with full tanks, 72 Lts useable with a still air range of around 4 hrs and able to cover around 360NM.
We flew over the factory and then on to a short 200 m grass strip belonging to a friend of Dietmar’s. Here I now experienced some of the tight maneuvering and although we did not land it showed that the gyro would have had no trouble at all with dealing with a small strip. Hands off it remained stable with not much stick shake, slipping in either direction made with no trouble. To the right with feet taken off the rudders it seemed to stay slipping before slowly correcting but to the left it did so more rapidly. With power reduced to idle and set up in a descent the glide seemed very shallow accustomed as I am to coming down like the proverbial brick, those winglets really do make a big difference. Back to St. Georgen, rejoining on a left downwind and in to land. We touched down close to the turn off, once again with minimal roll before the nose was down and we were turning off the asphalt.
On trying the front seat I was struck be the fantastic visibility and can only imagine that this must be similar to that experienced while sitting in an F16 cockpit. The seat has a number of positions for and aft but unlike a car this has to be done on the ground by removing a couple of seat bolts and is only a few minute job. I was very comfortable with the stick falling naturally into my hand as it was set, and Chis with even longer legs is very comfortable in the most rearward position still leaves adequate space and legroom for the rear seat occupant. The full canopy is quickly latched shut or opened hinging on the ride side. There is an emergency release knob on the right side easily accessible from front or back. The change over from full to alternative open canopy can be switched out in seconds by the use of the emergency release knob
The panel is well set up with analogue instrumentation around the MLG Voyager EFIS screen. This is simple to set up and use with a huge variety of customizable screens and instrument and Nav/weather/map displays. Everything in the cockpit and panel is ergonomically situated and within easy reach. The photos I have taken and hope to have up on the thread shortly should show much of what I have been talking about, sorry they couldn’t have been in amongst this at the appropriate places.
My expectations on the visit have been pleasantly exceeded in all areas, except of course the cost of the machine. But, when the long development and amount of testing that has taken place, along with the quality of the finished product, handling and performance achieved is all taken into account, even that makes sense. My congratulations to Dietmar and his team, they have produced a wonderful gyro that is to my mind and limited experience especially of the Orion and Calidus, very probably leader of the present field of modern two seat gyros.
With a very big thank you to Chris and Dietmar for the opportunity to see and experience a new cutting edge machine in the gyro world.
Uploaded photos to an album in photobucket. Still to be sorted and commentary added. But for now hopefully you should be able to see at least something. I uploaded the maximum eight for this post but clicking on the photobucket link will give slide show. https://s1246.photobucket.com/albums/gg605/Resasi/?albumview=slideshow
Below and in order we have OE-VXI which the demo flight was conducted in.
Dietmar the man with the vision of a better gyro and who flew the demo flight.
The front cockpit with canopy up showing the superb position the pilot sits in.
Pilot's eye view of the panel. Easy to reach great layout and an EFIS. Simple to use, hugely versatile, with an almost infinite possibility of customizable layouts. Chis has set some up some particularly suitable for this machine.
I liked this next view of the front cockpit looking almost like a jet fighter.
Yes, very happy and full of anticipation.
The production line inside the factory. The red machine is Claudius's and very likely to be the first in the USA.
Chris standing proudly beside his machine.

But, when the long development and amount of testing that has taken place, along with the quality of the finished product, handling and performance achieved is all taken into account, even that makes sense. My congratulations to Dietmar and his team, they have produced a wonderful gyro that is to my mind and limited experience especially of the Orion and Calidus, very probably leader of the present field of modern two seat gyros.
With a very big thank you to Chris and Dietmar for the opportunity to see and experience a new cutting edge machine in the gyro world.
Uploaded photos to an album in photobucket. Still to be sorted and commentary added. But for now hopefully you should be able to see at least something. I uploaded the maximum eight for this post but clicking on the photobucket link will give slide show. https://s1246.photobucket.com/albums/gg605/Resasi/?albumview=slideshow
Below and in order we have OE-VXI which the demo flight was conducted in.
Dietmar the man with the vision of a better gyro and who flew the demo flight.
The front cockpit with canopy up showing the superb position the pilot sits in.
Pilot's eye view of the panel. Easy to reach great layout and an EFIS. Simple to use, hugely versatile, with an almost infinite possibility of customizable layouts. Chis has set some up some particularly suitable for this machine.
I liked this next view of the front cockpit looking almost like a jet fighter.
Yes, very happy and full of anticipation.
The production line inside the factory. The red machine is Claudius's and very likely to be the first in the USA.
