F-1 Rocket completed the flight to Florida / 2024 08 29 /

Frank Krause and his F-1 Rocket Evoliution have successfully completed their flight from Europe to America. Andrea Kastelic joined him at America's first airfield. Together they flew to their new home in Florida. Today we offer Frank's full story about the preparations and the flight across the Atlantic Ocean ( link HERE ). Thanks to Andrea and Frank for the beautifully prepared description, photos and video.

"Thanks to all who supported the project.

F-1 Rocket / Canada - Albany, USA / / 2024 06 21 /

"The weather forecast for Albany was good, but on the way the two weather model systems diverged again extremely. To put it bluntly, the DWD's prediction was wrong again. It's a good thing I didn't fall for the wrong forecast for Greenland."
"...as predicted, the weather got worse. Heavy rain, CB to flight level 250 and the upper limit of cloud cover rose to 14,000 feet. There was also moderate turbulence and I actually had to unpack my oxygen. I had to stay at 14,000 feet for the last 2 hours, the weather just wouldn't get any better. Albany reported a cloud base of 5,000 feet and a visual approach to Runway 1 was flown."
"The customs formalities went very quickly and the officials were very accommodating. Afterwards finally I could hug my wife again."
"After 4 hours 39, this day was also completed in terms of flying. Now it was time to restore the old setup, remove the additional tank and reinstall the rear cockpit."

Frank Krause & Andrea Kastelic


F-1 Rocket flight / Greenland - Canada / / 2024 06 15 /

Dear Team Termikas,
"I stayed in the fjord as long as I could, came up to about 3000 feet in the first layer, turn right to mountain of terrain, but I could see the tops in between the layers and flew towards the blue sky shining through the icy clouds. Reaching 10,000 feet I didn’t pick up a single piece of ice. So the plan worked out nicely again."
"Winds were forecasted with 25 kn, in real they have been up to 45…"
"Enroute I stayed busy to calculate how much fuel I had to pump from the turtlepac into my left wing tank not to overfill and not let it run too low. Every 40 minutes I pumped fuel for eight minutes from my back to the left. After four time 40 minutes, the tank was empty and I was back on left and right wing tanks."
"Just before landing at Goose Bay switched to runway 26, so actually flew a straight in approach all the way from Greenland. Touchdown after 4:20, ready for the night. Just a little customs and refueling."

Herzliche Grüße,
Frank „R.“ Krause

F-1 Rocket flight continues / Iceland - Greenland / / 2024 06 12 /

Dear Team Termikas,
"The decision has been made to leave Reykjavik on Tuesday the 11th.
The weather minimum in Narsarsuaq seemed to be a reasonable, however, icing was a problem now that the strong winds and turbulence were gone. A plan had to be made. I could have climbed up to level 180, the plane is capable, and I had oxygen with me, to avoid the icing on route. The approach was more of concern.
So the plan was to extend the final all the way from above the clouds or to decent over the water to VMC and follow the Fjord to the airport. In anyway I had to fly around the south tip of Greenland, because descending over land with those very high MSA’s in icing condition could have been lethal. That however, added another 150 miles to the flight and brought it up to four hours and 40 minutes, taking away any alternate option.
To make it even more difficult the two different forecast systems I used showed the freezing level in the same attitude, but the cloud clearance to fly into the field in VMC were totally different.

So, flying VFR into the field was my last option. Take off was at 0925. The enroute was easy, I was above the clouds and could circumnavigate some some cloud decks.
Then I started the approach. The freezing line was forecasted quite precisely and the ice melted away fast and came of the plane in big chops. But the forecasted ceiling and visibility seemed a bit euphoric…
But I was still quite some distance away.

Then, finally, the weather report from the airport came true. I landed on one runway 26 with 15 kn tailwind, which was no problem because the runway has a nearly 2° up slope. I parked on the ramp, got fuel and a very good service for the next flight.

Well, the next problem: how to depart and avoid the icing?"

Herzliche Grüße,
Frank „R.“ Krause

F1 Rocket / 2024 05 31 /

"Flieger" Magazin published the first issue for the new year 2011 with the inscription: "F1 Rocket Evo. Die geht ab!"

But it all started in 2009 when we received parts for the F1 aircraft assembling from the USA. "Termikas" assembled the aircraft, painted it, made a unique engine cover, and installed the engine and avionics.

The aircraft was registered on 7 May, 2010. Frank Krause and Andrea Kastelic flew home to Germany.
Since then, our service team has been making annual visits to Itzehoer Aerodrome in northern Germany for maintenance. The cooperation continued for 15 years.

Frank decided to move to the USA. He chose to take his aircraft with him by flying from Europe to America. Wanting to cover this distance, Frank needed to install an additional 125-liter fuel tank, additional avionics, and a thorough check of the entire aircraft and engine.The F-1 Rocket EVO was back at "Termikas". Now, with full tanks, the aircraft can fly for 6:30 hours, covering a distance of 1200 mi ( 2200 km ).

Frank's planned route:
Pociunai, EYPR, Lithuania ( point of departure ),
Hungry Wolf Airfield, EDHF, Germany,
Wick, EGPC, Scotland,
Reykjavik, BIRK, Iceland,
Narsarsuaq, BGBW, Greenland,
Goos Bay CYYR, Canada,
Albany, KALB, USA, NY, ( pick up Andrea ),
First Flight, KFFA, USA,
Hidden River, 22FA, Florida, USA ( destination point ).

The distance: 4.852 NM ( 8.988 km )
Time: 27 h.
The upmost leg over the ocean: 675 mi ( 1200km )

Have a safe fligh!

Good luck to you, Andrea, and Frank
Good flights to you and your Midnight Pearl

Representatives from the State Aviation Administration of Ukraine at Termikas / 2023 06 17 /

On June 12-14, representatives from the State Aviation Administration of Ukraine visited our company.

Our cooperation with Ukrainian aviators began in 1995 when we started repairing the aircraft for the Kyiv Central Aero Club. We have worked with various aviation clubs, Defence Support Society of Ukraine (OSOU), the National Aviation University of Ukraine, the Aerospace Institute, and private pilots for many years since then.
In 2016, as Ukraine integrated into the European aviation safety structures, our EASA Part 145 certificate was recognized by Ukraine in the general aviation field.

During the recent visit, we saw the differences and became more familiar with the needs and regulations of Ukraine in this challenging period.
Both sides believe this will help Termikas to work with Ukrainian registered aircraft and the State Aviation Administration of Ukraine to integrate more quickly into EASA's General and Experimental aviation.


YAK aircraft & RED A03 V-12 Diesel

On March 9, 2009 "Termikas" has signed an agreement with the German company "RED aircraft GmbH" ( Raikhlin engines development ) to modify the Yak-52 aircraft by replacing the standard engine M-14P ( 360HP ) with a new RED A03 V-12 Diesel ( 500 hp ) engine and to additionally install hydraulic and electrical systems.
We performed fuselage and aircraft systems modifications. Company "RED" installed its diesel engine and assembled engine control and monitoring equipment.
With the participation of specialists from both companies, the aircraft was finally assembled and tested in Adenau, Germany. Test pilot - Antanas Marčiukaitis.
In 2010, the aircraft was presented at the largest European aviation exhibition in Friedrichshafen.

Today we present the 4-seater Yak-18T aircraft. "Termikas" and the project engineer Jonas Janušauskas modified and prepared the aircraft for the installation of the RED A03 V-12 Diesel (500 hp) engine. The engine was installed at the company's "RED" base in Adenau, Germany. Test flights were conducted there. At the end of July, the aircraft was registered in the Lithuanian register LY-BID and flew to our airfield. Test pilot – Žilvinas Lidžius.

"Termikas" will now do some work on modifications, testing and aircraft appearance.

We are looking forward to the visit of "RED" representatives soon.
Together with colleagues from "RED", we will tell you more about this project later on.
