Re: high speed taxi
DorotheaKeats and ChrisWalterson <dkeats@...>
Neil Jepsen------- Good to see the taxi problem is solved. If you
have the T-tail, I am assuming you have no reflexor. If this is the case and your C of G is in the back half of the envelope, you may want to try to reflex your ailerons up a bit to give the wing a little less lift. Go only at small increments. Just a thought-------- Canada Chris

O-200 cooling
Justin Mace <n764jm@...>
Jim Patillo & or Bob FarnamI have a chronic over cooling problem with my Dragonfly/O-200. I am curious what size your cooling inlets and outlets are. I currently am running two 4" dia round inlets like the LoPresti or Lancair cowls, they total 24 sq" inlet with a total of 44" outlet with cowl flap open and 12" closed. This time of year I am running with the cowl flap closed even on takeoff. I just came back from a flight and found the OAT of 62F running 22"mp @ 2500 rpm & 140kts my cylinder head temps are running 290 with the oil temp at 150. My oil has been very cool since I installed the engine and I am wondering how your inlets and outlets are sized. Two different senders in the oil read only a couple of degrees difference. I understand I need to run the oil temp up around 180 but even in the summertime its hard to do with the oil cooler in-circuit. I currently have a piece of cardboard covering the oil cooler so no air gets to it. I think the only saving grace for the oil is that here in the desert the humidity many days is single digit and even in the rainy season it is hard pressed to get over 50%. I am currently thinking about reducing my inlet size to about 18" total to start with, any ideas?? Justin Mace Tucson,AZ

Re: Engine mounting bolts...

The nice thing about the internet, Dave, is that it is easier to ask 45Proof that literacy is dropping in America. Of course, the head-shrinks thinkthat a great deal of Americans are suffering from lack of attention. Unlike aYeah, it also gets YOU some attention, eh? Jim, Without the internet and this list, there probably wouldn't be a single Quickie, Q2 or Q200 being built or rebuilt at this point in time. Reading Q-talk is definitely reccommended, especially the ones that were out before this list was established, but there is some information and knowledge available on the net that cannot be found " on paper" no matter what you read and some folks (other than you apparently) are willing to share even the older info with those who request it. People can also interact with those who have common interests and get (oh my god no!) HELP with problems, some that are covered by Q-Talk and some that aren't. As Pat stated, reading the parts in the original plans and old Q-Talks that have been ammended or changed might be fun, entertaining, nostalgic, or even informative from an evolutionary standpoint, but all this old and new info is readily available here by just asking for help. I wonder how most Q folk find out about the QBA, Q-Talk and the list to begin with? I know I found out about it on Tom's QBA site and I had to read every word of it, albeit on a computer monitor instead of on a xerox copy. Literacy, last I checked, concerned the ability to read... whether it was text on a monitor or ancient Sanskrit wasn't relevant. Had I not found this group on the internet, I would not have even considered the Q200 as there is no longer any other form of support for it. Other than the limited forums at Oshkosh and Sun N Fun, this is the only way for people spread out over such a great distance to come into contact and exchange ideas (some of which you do not agree with, but that is the advantage of this list... multiple points of view and no waiting). My plane came with all the Q-Talk copies from the earliest to 1996 and the interesting part is that just about all the articles deal with the same topics, problems and rantings that I see every day on this list. I would much rather delete all the Posa carb and Revmaster questions and save those topics of real importance to me in a folder on my computer instead of having a file cabinet full of mostly useless paper that outweighs my plane. Compiling the old Q-talks on a CD would certainly be a great idea, but it would also be a whole lot of work. Of course, it still wouldn't be on paper. If the recurrent questions on the list bother you that much, why are you still on it?

Brian Bulaw <BrianBulaw@...>
Neil,
You're pretty lucky you didn't reach flying speed. I you become airborne with full back stick you've got a good chance of going into pitch buck starting from 10 ft. agl. Been there. No fun. Back stick on the elevator does nothing to get your tail on the ground as long as your wheels are still on the ground. This isn't a Cessna. You're better off taking off with pretty much neutral stick on a long runway until you get some experience at altitude. Good luck.

JMasal@... wrote:
Chris you should be a poster child for "Builder Doing It Right."<snip> Owning past QTALKS and even reading them all is a big committment. My first day on the job working for a large commercial construction company, my boss sat me down with a set of plans, the spec. book, and a stack of addendums. The task at hand was to read through the addendums, and transfer the relevant information to the blueprints. So I started with the first one. Marked the plans accordingly, photo copied paragraphs from the addendum and taped it over the the obsolete text in the plans, etc. I was quite pleased with my progress as I was getting through the process, until I came to newer addendums which superseded the older ones I had already transferred to the plans! So now I was removing notes that I had just spent hours adding to the plans, adding to my head, adding to the critical path, etc. I quickly learned my lesson, and any time after that, I read the addendums from the newest to the oldest. How is this relevant? Years later, when I bought my partially complete Dragonfly, which came with volumes of newsletters, I opted to read them from newest to oldest. This paid off in several ways, most notably with the things like the brake system. The newest newsletters assumed that everyone had differential toe brakes. Toward the middle I found the first article on differential toe breaks, in the earliest newsletters I found the the company owner claiming that differential toe breaks will kill you. Same for engines, later newsletters had articles on successful 0-200 installations, as I went back I read of 80hp VW engine crank failures, further back, the 60hp engine was introduced with a warning that anything bigger will end in death, and back at the beginning, 40hp was the absolute limit, period. By reading newest to oldest, you can skip the older stuff, which might be great history to know, or even quite entertaining, but if (as I did) you get to a part where someone has written up a great article on a really sweet single lever for his cable operated brakes, you can opt to skip it as it probably has little or no relevance to what you are building or already have, or was since proven to not work well. Hope this helps. Pat

It means you do your homework BEFORE sticking your foot into it and buying a bargain pig in a poke. Owning past QTALKS and even reading them all is a big committment. Even having produced most of them I am frequently surprised over the copy machine to read tips that have completely left my head. There is just too much stuff in there. We ought to go to a two-pager so we can keep up. But there is still a mass of stuff that has gone unprinted. Thanks for your due diligence... you understand I am ony cranky about the dopes.
