RT DESIGN turbo KARAT V2

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.

– 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

Equipment:
JETI duplex REX12
JETI RC-Power Switch 10A
Hacker / Ditex Servos
Special FIALA 5-Blade Propeller

Athletes ceremony of Baden-Württemberg in Stuttgart

I followed the invitation from the secretary of state Baden-Württemberg, Volker Schebesta, to the new castle of Stuttgart on 11th of November. Sportswomen and sportsmen from more than 500 various sports classes were invited. All who achieved a podium ranking in 2018/2019 season in European or World Championships. My invitation was for the bronce medal on the 2018 European F3A Championship in Belgium.

In the white room of the castle the ceremony for athletics, bikers, boatmen… and aeromodellers too part! Besides me was one more rc-pilot. Marcus Haussmann, reigning F4H World Champion (scale class). I was happy to meet one more like-minded so we shared the experience together.

In small groups we went on stage to receive the gift from the president of the sports committee Baden-Württemberg, Mrs Menzer-Haasis.

 

After the official part during snacks we had the chance to meet and talk to more interesting people and exchange our experiences in our sport and events.

 

I was very pleased about this honor and want to thank the state of Baden-Württemberg for the event!

First WorldCup of the season in Portugal

On the 25th and 26th of May was the first F3A WorldCup from the 2019 season in Leiria, Portugal. It´s around 130 km north from Lisbon close to the Atlantic.
From our club was not only myself attending this event, also Daniel Setzer who come back to F3A competitions after almost 20 years.

On Thursday we flew with our team from Frankfurt to Lisbon. All except me started 6 A.M. with Ryanair. My flight was around 2h later with Lufthansa, because I took the big box with the 2 airplanes inside.

Arrived in the hotel, we assembled the planes and took the rental cars to explore the area around. For the dinner we found an excellent restaurant directly on the Atlantic, recommended by Rui Ferrera. So the first day was a real success !

Friday was very windy but a perfect day for practice. The competition started Saturday morning.
There were 21 Pilots from Spain, Portugal, Israel, Germany and Brazil. Peter Uhlig was part of the Judging team together with 2 Spanish and 2 Portuguese judges. Roland Podevin from France was there to run his Notaumatic calculating programe which worked fast and excellent.

Daniel flew very well on saturday and ended up this day at 11th. On sunday he went back one position and finished the competition with a fantastic 12th place.

For me it was a tough battle with Juan Rombaut for the win. Saturday I was very close in pole position, after the finals we changed the positions and he won, I became second. 3rd place was 14-year old very talented Yuval Ben Israel from Israel.

It was also great, that my friend and boss of CM-Jets (one of our partners) Carlos Marquez visit us there and spend one evening with us!

At the end it was a very valuable weekend with a lot of fun, nice people, perfect weather and superb food in nice community! We would really like to come back next year!

A special thank you goes to Filipe Dinis Bernardino for driving my box from the airport to the hotel, the support there and the organization of this nice competition!

China im November 2018

After my tripto China in April, I had the chance to go there once more end of this year. In that time there was China´s biggest airshow which takes part every two years in Zhuhai. It was possible to spend one day at this event to check out some beautiful aircrafts and amazing flight displays.
From Zhuhai I went to some factories to check out their shop, the work and their airplanes. In that time we traveled over 2000 km with the car and train. Between the days in the factories I had the chance to spend one day together with Chinese F3A pilots on the airfield to fly and setup their planes.
At the end of my tour I spent three days in FALCON to see the latest stand of KARAT and gave a presentation to all workers involved in the project and informed them what happened in the past and what is next.
After nine exciting days in China I went back to Germany.

Here are a few pictures from my trip:

turbo KARAT- worlds first turboprop powered F3A biplane!

A year ago I heard that CNC Modelparts  from Switzerland offered a turboprop for the JetCat P20/ Kolibri. Immediately I decided to build a Karat with a turboprop myself. Due to the air intake at the bottom and at the top and the straight sidewall it is perfect for a turboprop conversion. Also the exhaust gas can pass through the two wings.
In December 2017 I drove to Switzerland with my JetCat P20 to pick up the Turboprop from CNC Modelparts. At the same time I shared my idea with Carlos Marquez from CM Jets in Spain, he immediately became enthusiastic about the new concept and promised me a custom made fuel tank for my model. Two weeks later I already received the new  Kevlartank  for my turbo KARAT.

FALCON received my order to build an adapter for the fuselage, which I can easily attach to the zero side thrust nose, due to the F3A Contra-Rotating-System, to receive the necessary side thrust.
At the Rotor Live Helicopter fair in Iffezheim, I discovered for the first time the innoflyer light system, which was new in the product line of Hacker Motor. I became 
impressed by the innovative, simple and efficient handling. During dinner with Andreas Golla from Hacker and Christoph Raible from innoflyer we started speaking about my special project, the turbo KARAT.
Andreas Golla suggested to equip the plane with an innoflyer lighting system. At first I had the impression he was joking, but when I realized he was serious about it I actually thought it was a great idea.
On a piece of paper I received from the waiter we determined the position of the light on the model, and ordered the parts immediately. 
After the Turboprop, all DITEX Servos and the lights were installed, the plane had to be varnished.  I was planning on an 
easy but also a bit scale finish. In addition to the KARAT I worked on a Scorpion from Aviation Design with a Patrouille Suisse color scheme, which I like a lot and it is visible in the air.
As the Turboprop and the lighting are both from Switzerland, I decided to adjust the color scheme of the Ptrouille Suisse so it matches the KARAT.
Before I installed the turbo, I painted the whole body area of the turboprop inside twice with BVM Heatshield to avoid prickly  heat in the carbon/fiberglass of the body. After everything was rewired and finished, the first flight took place in the beginning of May 2018.  Everything worked out perfectly right away. In the meantime, I had a performance problem with the turboprop, but this was due to small kevlar pieces in the kerosene filter.
The plane now has about 30 flights and everything still works fine.
At the end not the most spectacular plane I’ve ever built, but definitely one that I have the most fun with!
And just the worlds first F3A t
urboprop biplane – turbo KARAT.
Also I would like to thank everyone who was involved in this amazing project:
CM-Jets, innoflyer, CNC Modelparts, Hacker Motor, JETI model, PowerBox Systems, FALCON

German Champion class F3A 2018 with KARAT biplane!

On the weekend of the 15th and 16th September was the first and only time the german championship took place in MFC Hameln-Lachem. Due to differences in the DMFV and DAeC and a lot of rumors and instigation in the internet, the common competitions were already history after two years. However it was nice to see that during the DAeC competition the focus was on the aerobatics and on the companionship, so everyone could put their attention to the flights. The great weather and the efforts of the host club to make everyone feel comfortable, made the seasonal final a great success. 
On Saturday two complete rounds of P19 were flown. The third round was also flown 2/3 that day. On Sunday after the last third of the preliminary round was completed, and the problems with the Notaumatic scoring system were resolved, the top 15 pilots were able to fly two rounds F19 in the final. 
At the End I was a proud and happy winner of the german championship for the 7th time in a row.
The title is very special to me because it was the first time I took part with my own designed KARAT biplane.
The silver and bronze medals went to Christian Niklass and Nils Brückner. Gregor Wetzel won 
the juniors league ahead of Max Chrubasik and Marvin Ahlborn.

The formation of the national Team next year is not certain yet and will be planned by the federal commission of the DAeC.

Many thanks to the MFC Hameln-Lachem, the jury, Peter Uhlig and Raimund Schwitalla who made the DM still take place in spite of a troublesome year.
