1:12 Minimoa by Tony Ray / Pichler
After my stressful 5th semester at studies I had the desire to build something out of Balsa again. At the exhibition in Friedrichshafen I saw the kits of mini vintage gliders from Tony Ray at the Pichler booth. Right after the event I ordered a kit of Minimoa.With the support of my 3D printer and covered with japanese paper and Graupner Spannfix a really nice little vintage glider was born.
Check the pictures and see the progress of my little Minimoa.

BVM-Jets Ultra BANDIT
HAPPY NEW YEAR!!!
After a few weeks without any new report here I decided to drop a few lines about the UltraBANDIT proejct from last summer…
In 2018 BVM-Jets announced a jubilee version of their legendary UltraBANDIT which was a “must have” for my father. It took almost 2 years until he started to build the plane in January last year.
State of the art equipment had to be installed: brandnew JetCat P250, Hacker / Ditex Servos, JETI model CentralBox-220 with 2x 2,4Ghz + 900mHz Backup-RX, Electron retractsystem and a custom smoke tank from CM-Jets.
While my father was building the jubilee UltraBANDIT, I completely reworked the older UltraBandit. It got also an electric landing gear, stronger “Low Voltage” Hitec flap servos and a JETI model CentralBox-400 with 2x 2,4Ghz + 900mHz Backup-RX. The CB-400 is required due to the older Futaba LV-servos which need only 5,9V.
Overall it was much more work than expected, as the electric gear has completely different design and other measurements. That´s why I needed to remove some of the old gear mounts and let my friend cut new carbon flex-plates for main- and nosegear – Thanks Manuel!
In July we finally made both maidenflights.
Conclusion: The “old” UltraBANDIT is still in a league of its own. The quality, the details and the extremely balanced flying is in my opinion still unrivaled.
All the work paid off, both airplanes fly excellent! Especially the JetCat P250 with its fast start, fast throttle response and the support of turbine telemetry make it a good progress in turbine flying.
The knowhow in this 15 year old design is still in the pole-position!
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 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!

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.

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 😉
