These are pictures from our SF260 French Connection

Here I am with my daughter on the wing of a friend's Spitfire.

Raymond in his SF260 flying over Paris France. Picture 2



Here is Raymond's plane at the Reno Air Races. It is a Yak 11-R2000 and was shipped to France in March of 2009.

This is probably a glider but the ME163 and the ME263 could have only been flown in a totalitarian country. It went to 48,000 feet in 3 minutes and there was no pressurization. Having survived the decompression chamber was no indication that you would survive in the ME163. Although they were faster than anything else flying and had a 37MM cannon, they only shot down one B17. When they were out of fuel they had to dive for their field where they would circle inside the protective range of their Anti Aircraft guns because if they glided down they were easy prey for any of our fighters. One pilot was coming back to his field and started doing loops and rolls and a P-47 shot him down. There was an effort to get the the ME163 to ram the bombers but this never happened. The ME163 took off on a carriage that would usually drop off. It then had a skid that was deployed before landing. If the skid did not deploy so that it was spring loaded, the landing was so rough that the pilot's back would usually be broken.

A rocket propulsion fighter interceptor the Me-263 was developed from the Me-163, which had been in serial production even though it had several defects. It had a short range because of the limited fuel supply. It was also very dangerous because occasionally fuel would leak and the tanks would explode. To eliminate these defects a new version of its engine was designed. It had two combustion chambers. The main chamber was called the starting chamber and the auxillary one the thrust chamber. This type of engine was used in the Me-163 version, but was further refined for the Me-263. Keeping the midwing monoplane idea, a longer and better streamline fuselage with a drop shaped cockpit and better automation was designed. The undercarriage conception was completely changed. The first concept of a caravan takeoff system and ski-landing gear was abandoned and replaced with a retractable gear. The Me-263 had a tricycle retractable undercarriage. The unwise decisions of moving the production from Messerschmidt to Junkers and then back again had delayed the finalization of the program. The first test flights, without an engine did not take place until September 1944. The fully prepared prototype was said to have made many flights but the end of the war prevented serial production of the model. In 1945 the plane was taken by the Russians and moved to the Soviet Union.
Range 165 km.
Climb 70 m/s or 70X3X60=12,000 feet per minute.
Top speed 1000 km/hr.
Cruise 700 km/hr
Weight 2,100 kg
Loaded 5,150KG

Exhaust temp of the 163 was 500 degrees
Exhaust temp of the 263 was 1,200 degrees.
There was no rudder control at low speeds so we put a small rudder in the exhaust. This worked in the 163 but was destroyed in the 263 because of the temp.

After the war DeHavelin modified the plane with a turbine engine and tried to break the sound barrier. He was killed in the attempt.
