Faszination Modellbau and airshow “Stars des Jahres”

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 PuchtingerFrank 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!

Airshow in Györ, Hungary

From 19th .-22nd. August was the annual SRCM airshow in Györ with the main event on August 21st. My Hungarian friends asked to bring back the Pilatus PC-21 and the small Tortuga. This year also with a little surprise: my brandnew 50% Bücker Jungmeister with the Fiala 5-cylinder 250ccm radial engine.

It was again an absolutely amazing event with perfect weather and a warm hospitality – check the pictures ;).

THANK YOU SRCM Györ for an awesome event!

A special THANK YOU goes to Hannes who provided an excellent accommodation for us!

KARAT biplane build report

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.
Isaac Najary from Israel writing in famous american RC-UNIVERSE forum a detailed report of his KARAT biplane building.

Thank you very much, Izzic! I am very excited to see the result 😉

Acrostar mk2 XL repair

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 😉

TSAR monoplane in 2021 RT DESIGN livery

During last year I worked on a completely new livery. It was time for something new for TSAR monoplane, as the KARAT-livery is already from 2017.
I am very proud now to show you the 2021 RT DESIGN livery on TSAR.

Which requirements I followed:

–          maximim visibility in the air (big difference top – bottom)

–          less different colors

–          quite a simple scheme

This scheme is the first ever we did completely with vinyl-stickers. The result is good and with 120g extra weight to the white body it’s excellent.

I hope you like it 😉

Arcus 6,06 m and DG-1000 6,66 m

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 MotorJETI modelFALCON and Tailored Pilots for joining this project!

Welcome 2021!!!

Unfortunately due to my studies and COVID-19 I was unable to fulfill my 2020 wishes but it was still a good year nonetheless.
The TSAR monoplane project was unfortunately not completed in 2020,it has now been over a year and is still not finalized but I am getting closer to the end.
With that being said I would like to introduce to you the all new, TSAR monoplane from RT DESIGN.

Stay tuned for more pictures of the new highly visible colour scheme.

I would like to thank everyone for the support in 2020 and wish you all a happy, healthy and prosperous 2021.

 

Events in August and September

As there are almost no events this year, I could manage to fly with friends in Germany and Hungary.
From 28.08. – 30.08. I attended a small airshow for RC pilots only and not for the public, in Györ.
An excellent event with perfect organization and hospitality – thank you SRCM Györ!!!!

Beginning of September I went back to Mosbach for study. Less than one hour drive from Mosbach is the airfield of Michelstadt, which is in my mind for many years. In 2001 was an airshow at that field, where I saw one of my most favorite airplanes for the first time, the GeeBee R2 by Delmar Benjamin.
On Monday and Tuesday the local RC-pilots are allowed to fly at this place and I could not miss this invitation and spent some great time with the people there.
A big thank you also to all friends in Michelstadt!!!

Here are some impressions and videos from those trips.
Thanks to all for filming!
