<DIV class=plainMail>Mike, <BR>I mis-spoke and hopefully my correction made it on the list. I meant ELECTRIC Black Magic. I know you and Dean have pulled it off in Zen-like fashion. I'm not aware of any others, though I'm sure you'll correct me shortly. The point is that most guys won't be able to pull it off or will have enough self-doubts to even try. That leaves them with Sparks, Integrals, Prestiges, Abbras and a few more that may or not be obtainable in a reasonable time frame. And most of those won't make weight with a combination of less-expensive (spelled heavier) motors and battery packs. Many that do would become instantly obsolete if any significant repair such as torn-out landing gear enters the equation. What I'm going to propose is to take the motor batteries (not Rx battery) out of the equation and require a weight significantly lighter than a glow plane (my preliminary research indicates 8.7 pounds which is 2-1/4 pounds lighter than a
glow plane). This isn't really my idea. I've just worked<BR> up what I believe to be a solution to comments I've been hearing on the contest trail for a few years now. Everybody has the right to an opinion on it and should make their feelings known to their respective AMA Contest Board rep when the time comes.<BR><BR>Verne<BR><BR><BR>---- Mike Hester <<A href="http://us.mc805.mail.yahoo.com/mc/compose?to=kerlock@comcast.net" ymailto="mailto:kerlock@comcast.net">kerlock@comcast.net</A>> wrote: <BR>> <BR>> <BR>> Verne you're pretty much talking about just about everybody flying pattern. <BR>> Even a lot of the sponsored guys don't get nearly as much help as one would <BR>> think (you've been around Andrew and others so this is pretty common <BR>> knowledge).

The <BR>> ones who didn't, you can usually find a common denominator somewhere that <BR>> had they done it different, they wouldn't have been overweight. At least the <BR>> few I am aware of. But almost all of them that I am aware of that are flying <BR>> made it the first time. Some are even lighter than I have yet achieved. I <BR>> know of a few exceptions but don't know of any that didn't make it <BR>> eventually after some tweaking. If you follow the directions to the letter <BR>> and never get complacent, you'll make it. Usually with room to spare. In <BR>> almost every case the extra weight was picked up on the finish/paint,
or in <BR>> the selection and methods of sheeting. I don't know personally of anyone who <BR>> didn't make it easily on the second attept.<BR>> <BR>> So, it can be done. But I won't kid you, it's a lot of work. The reward IMHO <BR>> is the durability. I am still amazed at how much these things can take <BR>> before they break! (I thought Archie's was toast for sure last year at <BR>> Cincy!)<BR>> <BR>> LOL Zen building....ok, I won't argue that, me and Dean do have that <BR>> mindset. We actually enjoy the process. It's not work (unless it isn't <BR>> mine). We know we're the minority as far as that goes. Most people just want <BR>> to fly, NOW. But I enjoy the shop stuff as much as the flying.<BR>> <BR>> I really don't know of many planes that "can't" make weight under the <BR>> current rules. Some are just easier than others. But just for the record, <BR>> the Black Magics have a pretty good track record
overall, thus far. But they <BR>> aren't for everyone. There are plenty of composite planes that can easily <BR>> make weight. Although you sort of get what you get, and hope it's light <BR>> enough in almost all cases. The only way to totally avoid that is to do it <BR>> all yourself. And although there are a suprising number of people who will, <BR>> a lot can't, or won't.<BR>> <BR>> FWIW the future is looking better than ever, across the board.
