F3C & F3N TEAM TRIALS
Championship Team Gold for British team
2011 Control Line European Championships Medals – the magnificent F2A Speed Team,Ken Morrissey, Paul Eisner & Peter Halman, took the championship team gold medal for the 14th year in succession. Seven World Championships and seven European Championships. The individual bronze medal went to Paul Eisner and the gold individual medal, European Champion’s crown and a new world record went to Ken Morrissey.
Jamie Griffin, our talented young F2D Combat flier, took the F2D individual junior bronze medal. That’s an individual junior medal for Jamie for two Championships in a row.
Ken Morrissey breaks the F2A World Record
Ken Morrissey breaks the F2A World Record four times at the recent European Championships with a final, magnificent speed of 307.4 kph.
Ken Morrissey was a member of the British F2A (Speed) team at the 2011 European Championships in Czestochowa, Poland. Ken broke the current world record of 302.5 kph each of the four times that he flew. His flight in the fourth and final round was an astonishing 307.4 kph.
The engine was a Halman Special, 2.5 cc producing 2.5 bhp and running at 40,000 rpm. Ken’s “pit crew” were the other two team members, Paul Eisner (individual bronze championship medal) and Peter Halman. It was Peter’s magic fingers that set the engine on each of the flights.
In the first round, Ken recorded 304.3 kph which smashed the current world record by almost two kilometres per hour. In the second round, he broke his own record by 0.1 kph. In the third round, he broke that record by a further 1.5 kph and in the fourth round, with another increase of 1.5 kph, he broke that record with a magical speed of 307.4 kph.
In four flights he took the world record from 302.5 kph to 307.4 kph. When the top competitors are separated by just tenths of a second – and sometimes by just hundredths of a second – then the overall increase in the world record of 4.9 kph shows just how astounding this achievement of Ken’s really was.
On lap 6 (of 9 laps) the TransiTrace electronic timing system recorded 309.3 kph. Nothing like this has ever been seen in F2A competition flying since it was first introduced as an FAI class. Ken was deservedly, and to wild acclaim, crowned F2A European Champion.
