Well Robert it would seem that the clockwise engines have just about run there course. As Pete Mazur says, he fly's just as well as the best (he being a large part of the best) with the counter clock wise engine. I've competed with Pete for around 15+years and never seen him get in trouble over anything to do about the clockwise verses counter clockwise engines. On the other hand Bill B. had a big influence on me as far as using clockwise engines in carrier. He used Fox and then a Wylie (spelling?) which both used the Fox clockwise cranks and did so well that I went out and got a Nelson with a clockwise crank engine and from then on I used the clockwise engines in all of my AMA competition planes. The big difference in the use of either type engine is who is using them. The top carrier fliers can fly either engine and win/place well, because they know how to fly carrier and have flown the events over many years (practice, practice, practice). So I would suggest "don't make the clockwise engine" your main ticket to success.
Have you heard the saying "be carefull what you wish for". I've been watching BCD events all over Europe over the last 5 years and have noticed the good turnouts, close competition between fliers and the overall fun the contestants seem to be having and find myself envying your carrier competitions. Here in the States the turnout in competition in pretty poor, that is very disappointing to me and the group that are actively flying carrier here. Henry Nelson made his carrier engines available to anyone that wanted one and I'm pretty sure there are hundreds of these engine out there that were bought by people that wanted to compete and win but in the end didn't want to put the effort into it that would allow them to win.
So the engines are out there but it does take some effort to get one. Then after you get it, then begins the work to get to the top, and with rare exception there is not many that will do the work to get there. Eric
