A year ago I heard that CNC Modelparts \u00a0from 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\u00a0through the two wings. \n<\/span><\/div>\n

In December 2017 I drove to Switzerland with my JetCat P20 to pick up the Turboprop from CNC Modelparts<\/strong>. At the\u00a0same time I shared my idea with Carlos Marquez from CM Jets<\/strong> in Spain, he\u00a0immediately\u00a0became enthusiastic about the new concept and\u00a0promised me a custom made fuel tank for my\u00a0model.\u00a0Two weeks later I already\u00a0received the new \u00a0Kevlartank\u00a0\u00a0for my turbo KARAT.<\/span><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
\n<\/span><\/p>\n
FALCON received my order to build an adapter for the fuselage, which I can easily\u00a0attach to the zero side thrust nose, due to the F3A Contra-Rotating-System, to receive the necessary side thrust. \n<\/span>At the Rotor Live Helicopter fair in Iffezheim, I discovered for the first time the innoflyer light system<\/strong>, which was new in\u00a0the product line of Hacker Motor. I became\u00a0<\/span><\/span>impressed by the innovative, simple and efficient handling. During dinner with Andreas Golla from Hacker and\u00a0Christoph Raible from innoflyer we started speaking about my special\u00a0project, the turbo KARAT.<\/span><\/div>\n
Andreas\u00a0Golla 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\u00a0actually thought it was a great idea.<\/span><\/div>\n
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.\u00a0<\/span><\/div>\n
<\/div>\n
After the Turboprop, all DITEX<\/strong> Servos and the lights were installed, the plane had to be varnished. \u00a0I was planning on an\u00a0<\/span><\/div>\n
easy but also a bit scale\u00a0finish. In\u00a0addition to\u00a0the 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. \nAs 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.<\/span><\/div>\n
Before I installed the turbo, I painted the whole\u00a0body area of the turboprop inside twice with BVM Heatshield to avoid prickly \u00a0heat in the\u00a0carbon\/fiberglass of the body. After everything was rewired and finished, the first flight took place in the beginning of May 2018. \u00a0Everything 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. \nThe plane now has about 30 flights and everything still works fine. \nAt the end not the most spectacular plane I’ve ever built, but definitely one that I have the most fun with! \nAnd just the worlds first F3A t<\/span>urboprop biplane – turbo KARAT.<\/span><\/span><\/div>\n
Also I would like to thank everyone who was involved in this amazing project:<\/span><\/span><\/div>\n
