it was completely new frame-must bought from Auto-Gyro and reparation done by Rene itself ... it is hard to judge now - but facts are facts (video, photo)
Inox will never brake on weld line, it will brake near welding line.
Rene comment that it is strange for him that one tube broken like glass and second tube is broken like plastic (fully deformed) - from this facts he make conclusion that one tube just brake in flight and after was strike of blade against tail tube and after canopy opened it is his version of truth (which no one will most probably will not know what happens in reality)
Better translation: The amazing thing is a half blade which broke off on impact with the ground and was found 200m away. I saw the canopy open, extended my arm to close it but it was impossible. I was still flying the aircraft in a straight line on takeoff. It as still stable and right after bringing my arm back I heard sort of a bang and then found myself in the ambulance. I have no recollection of the the trajectory to the ground. The first person who ran to my rescue saw me stagger out of the gyro and collapse 4-5 from the aircraft. I only have this short video to show the trajectory.
I had canopy opened once in a Calidus in flight while turning from base to final. It was right turn with some left slip thus airflow from the left made canopy rising not that quick. I was in the back seat with a student in front one. Our left hands rised at the same time (our preflight briefings with students include this situation), caught the canopy, put it back to its position then student secured it.I was on short final when suddenly, with a bang, the canopy flew open. I was doing about 90 km/h at that time and guess the engine was doing about 3000 rpm. The gyro yawed violently to the left because of the added drag of the open canopy on that side.
My personal accident investigation revealed that I might not have closed the canopy latch fully and might have inadvertently opened it with my left elbow, although I don't remember either.
during takeoff approx. 10 meter high the mast broke just at the top of the fuselage near the welds. It was the second take-off with the new metal chassis, the first flight lasted 30 minutes.
Following the previous owner who had a bad takeoff and damaged the autogyro, I bought the wreck and completely rebuilt the machine with new parts from AUTOGIRO (Germany) about 20k euros of new parts.
The Calidus is 65h old. see the video : https://www.youtube.com/watch?v=p-cu7JvTpxw
