It all started when I was a boy with the Graupner MC-24 gold from my father. I thought it´s a cool and beautiful radio. That time I already knew I want such a transmitter someday!
Almost 15 years later I hold a JETI duplex DC-24 in my hands, with almost each part and switch 24-carat gilded. Probably the worlds one and only DC-24 with such a finishing. The name: DC-24K.
„When modern carbon meets classy gold to end up in world’s finest radio.“
But until I had it in my hands, it was a very long way. It took more than one year until the radio was completely finish. I think with the gold color it describes the quality and valence of this product best.
"Before gilding all aluminum parts, they have to be polished to a high level gloss and after that galvanic nickel-plated.
The quality of the aluminum polish is decisive for the final result. Finally the galvanic 24 carat gold plating takes place."
Only with the support of good friends we could realize this exclusive unique masterpiece.
Therefore a special thank you to: Lenka, Hendrik, Jörg, Jürgen, Jakub and JETI model!
On saturday, 23rd of March, Mr. Hacker invited to his 20-year-jubilee of Hacker Motor in Ergolding.
A great event with famous guests, interesting guids through the company and an exhibition of their projects in RC-business and industry made this day to one of the highlights in 2019.
Even the weather was perfect with a deep blue sky and warm temperatures, maybe also a merit of the past 20 years.
What started in the loft of his families´ house is nowadays a mid-sized company with almost 40 employees and projects around the world.
For more than 10 years I am Pilot for Hacker Motor. Since my beginning I trusted in the products from Bavaria. When I look back, that was probably my best decision I made in my rc-career. I am more than proud to be part of this team since that long time.
For some time Hacker Motor is also the exclusive distributor in Europe for my RT DESIGN models- nothing better could happen to me!
At this jubilee last week we took the chance to introduce my latest design coming this summer the market: Acrostar mk2 XL – the big brother of our 6S successor came to the market last year.
(More information about this plane coming soon.)
Again congratulations to Rainer Hacker for 20 years of Hacker Motor GmbH!
I´m looking forward to the next 20 😉
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:
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 turboprop 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
Many thanks to Philipp Rösner for another great video of turboKARAT!
On the 18th of August JETI hosted the annual JETI model Meeting.
A few top pilots supported by JETI came to CZ for making the airshow interesting and diverting with many highlights.
Especially all those scratch build airplanes from the Czech pilots also taking part in the show are stunning and make it worth to join this event.
Martin Pilny made some really great snapshots of my Pilatus PC-21- thanks for them!
Thank you JETI model for the invitation and the awesome weekend!
I would like to introduce you a project I am part of.
It is the StickMover by AVIrem!
It looks like a radio, but this device is not sending. There are 4 digitalservos installed which are moving the 2 sticks.
What does StickMover do?
You are watching a video of a complex heli or airplane maneuver while holding the stick mover in your hands. Your fingers are on the sticks like on a real radio. While the video is running the StickMover moves the sticks synchronous to the maneuver in the video.
It shows exactly how to fly the maneuver in any speed you choose. You repeat this until you feel safe and ready to try it in real or in a simulator.
The StickMover “takes you by the hand” for every complex maneuver.
What has Robin Trumpp to do with it?
Next to the helicopter aces Eric Weber and Nico Niewind I am responsible for the airplane maneuvers in the programme.
The maneuvers are not created by a computer software, they are all flown with a lot of effort and diligence from real rc-pilots and embedded by the StickMover team to the AVIrem software.
Who is behind the StickMover?
Developed was it by Patrick Zajonc and Ulrich F. Beyle and is after 4 years almost ready for everyone. To make it available for you those 2 guys need your help!
Because the injection mold for making the case of the StickMover is very expensive.
Support the Kickstarter campaign from 15th of February and help to realize this project and get the StickMover to a special price.
DO IT FOR OUR HOBBY!!!
-in the Kickstarter campaign from 190€!
– all radio modes
– replay the videos in any speed (ultra Slowmo until realtime and even faster)
– continuously growing maneuvers
– special flights from events (Euro and World championships, airshows..) after it online and ready for “feel them”
Support the project HERE:
Finally in our hands, the brandnew JETI DC-24 in special RT-edition gold/carbon!
Here are a few pictures from the production of this highend radio which I would like to share with you.
Not only the design also the features and the quality is unique, but convince yourself!
More information about the JETI DC-24:
After 8 successful years with Futaba we changed in February our radio system and moved to Jeti duplex.
We are very proud and happy that Rainer Hacker (Hacker Motor GmbH) and Jakub Mitura (Jeti model) gave us the chance to this step!
Ewald and Robin Trumpp
