The spin was supposed to be a normal erect spin to the right, but for various unintentional reasons the spin went flat, up until that point I had never flat spun an aircraft. I eventualy mananged to get the aircraft into a normal erect spin from which I was able to recover. This aircraft is not fitted with an electric starter motor, so I was unable to restart the engine. During the "flare" to land the main undercarriage caught the top wires of a barbed wire fence that was invisible to me. After coming to rest inverted I waited 20mins for the rescue services to come and right the aircraft so I was able to exit via the outward opening canopy. The aircraft rotated 26 times total, I was extremely dissorientated after the recovery to straight and level flight, and was unable to read the instruments. From the video I estimate I recovered at about 700ft from an entry altitude of 3500ft. If you listen carefully you will hear me say:"I think this is it". At that stage I did not think I would be able to recover. However I continued to try various control inputs based on the aircraft attitude and rotational rate, which eventually effected a recovery.
My thanks go to the emergency services that found me and allowed my escape.
