I was detailed b F/Lt. Smets to take the Martinet to Ouston and Church Fenton. I carries out a cockpit check at the end of the runway, working round the cockpit from left to right to see that everything was in order. As the Master has a different C.S. Control, I did not notice that the Control on the Martinet, which is smaller and in a different place, was in coarse pitch. I have done about 100 hrs. on Masters but have never flown a Martinet. Before taking the Martinet I was shown the working of the petrol cock by a pilot of the towing flight, but thought the rest of the Cockpit was the same as the Master. I noticed the speed was slow when I opened the throttle, but thought it was because I was used to the Spitfire and because the Martinet was a fairly heavy aircraft with a less powerful engine. When, about half way down the runway the speed was only 65 m.p.h. I realised I was in coarse pitch and tried to get into fine, but could not find the leaver in time and went through the far hedge coming to rest in a field
