After the fair had to be canceled last year due to COVID-19, it was great that they opened the doors from 5th-7th November again. Friedrichshafen is known as THE fair for rc-enthusiasts in Germany!
Unfortunately there were not that much exhibitors than in the past years, but all those who took part were rewarded with numerous of visitors and good conversations.
I had the chance to present my new 50% Bucker Jungmeister at the airshow “Stars des Jahres” at the airport next to the fair.
I was invited a few times in the past years but for me this was one of the best, maybe the best fair in Friedrichshafen ever.
Great atmosphere for visitors and exhibitors, excellent airshow with many great pilots and a perfect organization. Truly one of the best weekends this year!
I´d like to thank the VTH-Team at the flightline, especially chief editor Uwe Puchtinger. Frank Joosten for great commenting on the show, Jörg for trouble-free communication with the tower and all others who were involved to make this fair a big success!
A special thank you goes to Andreas Maier and Markus Nussbaumer for providing their excellent footage and video for this report.
Thanks also to all who have helped and supported me during the weekend!

I am very happy to see one of the best builders we have in F3A building on of my planes and giving aeromodellers around the world the chance to follow each step he makes.

Thank you very much, Izzic! I am very excited to see the result 😉
Unfortunately a clubmember crashed my Acrostar and damaged the gear, the gear frame, the wing support, the landing gear covers wheelpants and cowling.
I thought about building a completely new Acrostar or just fix the fuselage.
I decided to do the second option and took some pictures during this process…
My message with this post: You don´t have to throw it away immediately 😉
After a few years without flying a scale glider, I wanted to have one again. The Arcus by Schempp-Hirth is with its unique wing shape one of the most beautiful gliders in the present so it had to be an Arcus. End of 2019 I was together with Erwin Schreiber from RC-Flight-Academy in Asia and on the flight back to Munich, 11.000 m above the ground, I placed my order for his Arcus. Right after my father joined the project and ordered a DG-1000 from him.
Due to various projects and my study we were unable to finish the gliders earlier. In a creative phase during study I drew the scheme for both gliders. Of course these 2 planes should also bear the spirit and signature of RT DESIGN. Based on this scheme I worked out another 2 versions of this livery for a new F3F glider and TSAR monoplane- more on that later!All the grey parts are 2K painted, the golden parts are realized with ORACOVER-easyplot.
As most of the customers buy the planes ready to fly, the building progress was laborius and took quite a long time. It took some effort to cut the slots and holes into the top wing of Arcus for the flap and aileron linkages. The following applied: cut and hope it was correct! All the linkages were made with high quality MP-Jet aluminum clevises and carbon tubes. The DITEX servos are all mounted in wood frames which are also available from Hacker Motor.
We wanted to install a self launching electric motor system, that we are not always dependent on a towing machine. As we have a lot of 10S packs from the F3A models, Hacker needed to arrange a power setup for 10S packs and the concept works excellent! Max current on Arcus is just around 55A and on DG-1000 it´s around 70A and a few several hundred meter climbs.
A few blowholes and areas where the white paint wnt off are needed to be mend. The good flying characterisitcs of the planes are bringing the troubles in balance. Almost no function had to be trimmed, the CG´s are reached without any extra weight in the nose, the drive dimensioning from Hacker is excellent and the super bright LED flash light make those gliders to a really successful project. Now we wait for days with good thermals to get them enough air-time!
We installed the Click-Connect system from Hacker Motor for the first time because of 5 servos in each wing plus the LED´s. That´s during building much more work, but in the end the most precious and safest solution for all the wiring and after crimping 2, 3 cables it´s quite an easy task. The result is a perfect reverse polarity protected central plug for all wires from wing to fuselage.
The power management system is a JETI model CentralBox 400 with two 2,4Ghz RSat and one 900mHz RSat. Each servo is directly connected to the CentralBox and can be programmed individually. That make the flight conditions and landing setup (airbrakes + butterfly) very easy in setting up. The CB-400 has still enough pins for the 3rd receiver and all the telemetry inputs. Telemetry from the CentralBox itself, each receiver, from the ESC (current, capacity, temperature…) and from the MVario2 are delivered in real time to the radio and gives a great overview about the safety onboard. As already installed and loved in other planes, the RC-switch is also here a must. The batteries are Hacker TopFuel ECO-X 3000mAh 2S.
I heared a lot about Tailored Pilots from England, but never had one of these pilots in my hands. After carefully checking their website it was sure that those pilots can meet our expectations. A few eMails with Wilson Li from Tailored Pilots later the order for 3 pilots were placed. What I can say after getting them is: quality, weight and detailing are surely one of the best available today. And they have a wide range of accessories to choose such as seatbelts, sunglasses, parachutes, headsets… Really nice are the RT DESIGN baseball caps he made in the correct size for our pilots.
A big “thank you” goes to Hacker Motor, JETI model, FALCON and Tailored Pilots for joining this project!

THE GAME-CHANGING TURBOPROP MODEL!
Beginning until mid of this year I was very busy due to my study. So I could not invest the time for aeromodelling as I wished to. But in the past weeks I worked up and finally after more than 1 year the new turboKARAT V2 was finished.
When my father flew turbo KARAT V1 he said “I need one”. So we shared the work and built 2 new turbo KARAT V2.
What has been changed from version 1?
– stronger and lighter turbine, now Kolibri T35
– special FIALA 5-blade wood propeller
– special exhaust pipes for the small turboprop
– all new colorscheme “bronce-NAVY”
– new Hacker / Ditex-EL Servos
– reworked LED-light-system from innoflyer
– reduced go-fly weight
