We are. Facts can be uncomfortable things. The personal attacks on me from the likes of you and dana Overall are unplesant. However, I do take great satisfaction in seeing that what you each have thrown my way is merely your opinion and your emotional reaction to my statement of the facts. You are entitled to your emotional opinions and Dana to his foul mouth. Neither provides any evidence to refute anything I have said. Once again we are in a war where Americans are risking our blood and treasure to keep ourselves and others free of terrorism. As usual, we and the British are doing it largely alone. Thus I ( a combat veteran) am not particularly inclined this morning to kiss the behind of my foreign inferiors. Dean Allen __________________________________ Do you Yahoo!? Yahoo!

My KR2 is standard width and length and if I move my legs, I usuall touch the stick. If I try to read a map, something touches the stick. After the first year or so of flying I moved the engine forward for better balance. The Aircraft is pitch stable as long as once trimmed, I don't move. Since that's not likely, when my attention is diverted like while looking at a map, I have to make frequent scan's to make sure I don't enter an unuasual attitued, which can happen very quick in the KR.

While I stand by my opinion that the metric system would be an economic disaster for the U.S., I also realize that this list was NOT the appropriate place for me to express my opinion. I knew very well that this list is dedicated to our common love of aviation. The fact that I was provoked by some personal attacks against me does not excuse my lapse in judgement. I did make most of my replies to this subject off the list privately and have made some new friends (foreigners believe it or not!) in that manner. Anyway, I was wrong to go so deeply into a non- aviation related subject on this list. I do deeply regret doing so. I also sincerely apologize to everyone except Dana Overall whom I believe should apologize to me. Anyway, you have my firm promise not to post anything else here that is not aviation related. That promise is good whether I am provoked or not. Anyone wanting to discuss anything with me is welcome to do it off the list to agate12@yahoo,com. I hope this makes proper amends and we can all go back to posting and reading about aviation. Kindest Personal Regards, Dean Allen __________________________________ Do you Yahoo!? Yahoo!

Lynn Lynn and Colin, I just got back from my daily 5 mile run and was thinking about just this same issue (I have a lot of time to think when I'm not dodging traffic). My longest pushrod is 81.5". Although the wall thickness narrows to .035 the diameter increases from from .75 to 1.5 a twofold increase. Another thought while out running surfaced in that all short pushrods are narrow thick walled tubes while the two long pushrods form the the control arm to the aileron bellcranks are like the long elevator pushrod.......thinner walled, greater diameter. My non engineering thinking is you achieve greater integrity with more surface area with thinner walls for lack of a better way to describe it.
