[RCSE] Re: Pouring lead into tubes
Dennis - I've found that If I left the tube ends lightly rolled (just like the tube cutter leaves them) the lead stays in fine. I'd recommend against doing anything while the lead is still hot - molten lead is scary stuff. If the lead falls out just use a larger tube, pull the lead out, and keep the tube for the next set of weights. For that really "high performance" ballast try a piece of CMW2000 from CMW Inc., of Indiannapolis, IN. 95W,3.5Ni,1.5Fe;.650lb/cubic in. It's much more compact than lead, and it won't get dented by much in the event of a hard landing (including armored vehicles);-) have fun - Rob Glover Greetings, I'm making ballast in brass tubes that are 1" dia and 1" long. I poured last night and the lead shrank in diameter enough that it easily fell out of the tubes. This might not be too much of a problem for a smaller diameter tube. Should I: Heat the brass tubes as I pour, Press the lead down before it cools and just after I pour, Epoxy the lead in after it cools, Press the cooled lead causing it to expand and match the tube[I can make a fixture to hold the tube to diameter], Roll the ends of the tubes to prevent the cooled lead from escaping[easy for me to do also]? I think any of those would work, what have you found that works for you? = Dennis Phelan RCSE-List facilities provided by Model Airplane News.

[RCSE] Re: Covering with Microfilm
A mix of something sort of like model airplane dope (but not quite) is poured over a wide pan of water, and it spreads out like an oil slick. The mix floats on the water until it sets, at which point a frame (submerged in the water) is pulled up under it Hey this brings back fond memories of my transmission electron microscope days when we did a procedure similar to this (we first poured a bit of the solution onto a glass slide, let it dry, then floated the film off the slide onto the surface of water) to provide an ultra-thin support for samples to sit on. The solution is called collodion. The solvent was amyl acetate (pentacetate--smells like banana extract), and the material that was dissolved in it was nitrocellulose--see http://www.collodion.org/qa.html. It was very tough stuff; I remember because I occasionally had to make up a new solution using the solvent and strips of nitrocellulose, and the strips were extremely stiff. We always did it in a fume hood. Although we wanted our films to be extremely thin, I'd guess you could control the thickness of the film by varying the concentration of the collodion solution.

RE: [RCSE] Pouring lead into tubes
Why not pour into tubes the same diam as your wing tubes. When the lead cools and shrinks, it will fit the wing tubes perfectly, with no jacketing. Just a thought...

Hi all, Just a note to tell people who have been keeping track of our woes that all is not lost, at least not that we know of. If anyone is interested in following this little saga, please go to our club website and check into the Project Maluhia link on the Club News page. If anyone has any input on how to approach the Boy Scouts to get written permission to continue to fly there, we are wide open to suggestions. Check out the link first, though, to see what we've already tried and what all has been going on with this situation.

There is excellent lift there probably 95% of the time, the weather is almost always ideal, the view is fantastic and the landing area is close to perfect.

[RCSE] perception of distance, hlg height etc
Human ability to percieve distance is largely a learned skill, and as with most 'seeing' tasks, we rarely realize how subject to error it may be. While distance estimates may be good in a certain environment, with certain kinds of visual cues, it is no surprise that when trying to estimate the distances of our hlg's, we might regularly err. There is very little up there to use for known object comparisons, focus comparisons, and even the overlap of receding landscape is not of much use. The glider is often the only thing to focus on and I think this leads to easy errors in perception. My experience suggests that we (rc pilots) tend to underestimate numeric distances, but overestimate actual positions (thinking we're further away in terms of being over a landmark, than we actually are). The few times I really methodically checked my ideas about 'how far out over the water' I was flying at my local lakefront hill, I was embarrassed to find out how much further out I thought I was than I actually was. I've since tried to modify my perception by always adding some margin to distance perceptions. If I'm cruising over to try to take advantage of lift over a far away mini-ridge, I always go a little further than I think it is. Who knows if this is helping!? Only more testing will give answers. I do have a real sense that it helps alot to move around and fly the same area from different places. If you're in the habit of always flying your local spot from one position, you might consider moving around some. I have a couple special spots I like to fly where I can walk the entire time that I'm flying, and I'll often get in two or three miles of travel in a flying session. With all the discussion, I am really curious how high my launches are, though I gotta admit, I tend to think of them as a lot less than a hundred feet! I don't really know whether my own errors are over or under in trying to put a number to heights, but when non flyers watch me launch my Chinook, I know that they almost always underestimate. They'll often say things like "wow, that thing really went up! What was that, maybe forty feet?" Well, like I said, I don't know how high my Chinook launch is exactly, but I can tell ya... its way more than forty feet. I thought a couple of the comments that Chris Adams made recently were interesting in this regard. He mentioned that in trying to work with the laser rangefinder to determine hlg heights, the pilots regularly were sure they were over the guy with the rangefinder, when in fact they were still pretty far off. I'd be curious to know whether that error was regular. (Were they always short of the target spot, or always beyond it?) I'd guess they were short, based on my experience... maybe Chris will tell us. Chris also mentioned that even after testing the rangefinder successfully, he still has a nagging perception that his plane isn't going as high as the rangefinder says. I think I'm going to do some more distance perception testing at the local flying spots. I'll be really curious to see what I can learn about my own errors, and any general tendencies. I'd be curious to hear thoughts on any of the above ideas. Lift, Scobie in Seattle RCSE-List facilities provided by Model Airplane News.

This may apply to smaller models such as sailplanes, however I think most people tend to underestimate how far away the model is when flying larger unlimited or cross country sailplanes. I have seen many people fly into the back side of a tree when they were sure they were nowhere near that far away. The best example of this was at Visalia a couple of years ago when Daryl flew his giant scale model into the back side of the factory southeast of the field.

[RCSE] Receiver antenna length? - safe to cut?
* Repost, we were having some problems with the list and it may have been lost in the shuffle** Hello, I have been wondering if it is safe to cut a receiver antenna length or is it somehow tuned to the frequency length. For example, in the old days, I would make my FM antenna 1/4 or even 1/2 wave-length to help reception. Is this true for the Rx? Is the antenna length tuned to the frequency range? Would trimming it a bit effect performance? Last part, I have built only fomies with strapping tape, but am progressing along now. What about some of the other coverings or materials how do they affect reception? For example, I have a HGL I am putting together with a carbon boom, if I run the antenna through the carbon boom and out the back-end, can it receive through the carbon ok? What about some of the covering materials such as Ultracoat or Econocoat? Do any of these materials have a refracting properties that would inhibit good reception? Thanks, with all the talk about the how receivers and types, I figure the best I can do at the moment is to make sure I give my Tx the best target in the sky.

[RCSE] Seattle July HLG Contest Results and SURVEY for all HLG Pilots
Hi All, It was another great day at 60-Acres Park here in Redmond, WA. There was a good breeze out of the North keeping temperatures in the mid-70's, clear skies and some pretty nice thermals made for a fun contest. A good flight could get you a 3 or 4 minute time, but the off-field landings were a problem for most of us! The Bush Pilot award goes to Al Bangham who ended up off field, and spent the next couple of hours looking for his plane. He returned triumphant, with several blackberry bush scars to prove it (we like to call those Battle Scars)! Some of the others of us ended up off field, but were able to find our planes a little more quickly. Structural failures were also a problem, wing failures, tail failures, and flutter kept several competitors from doing even better than they did. The Sticky Fingers award goes to Paul McKee who flew wonderfully his first round with his Uplink (in his first HLG competition), then went out for the second round, and on the first throw his entire vertical and horizontal tail assembly departed from the plane! The fuselage and wing continued for an 8.3 second flight, but that was all the more points Paul was to get that round. Not to be discouraged, Paul went back to his car and within 3 rounds, he was back with a reattached tail and new pushrods! He went on to fly quite well. The final standings had Mark Bryan beating out his brother Brent by a mere 77 points to take 3rd place. Come Back (again and again) Kid Joseph Conrad came out of nowhere to take 2nd place, and May's HLG contest victor, Dick Barker was triumphant again, this time by a hefty 343 point margin. (BTW, The top four places were all taken by Wing-Launched airplanes, see all the results at the bottom of this email). So, is Dick and his Discus Launch going to dominate the club? Will the Bryan family replace the Pearson family as the Seattle HLG Mafia? Will the blackberries be in season? All these questions and more will be answered at the next HLG contest, the big AMA sanctioned event August 19th! (www.reddata.com/sass/HLG_00.htm) Door prizes donated by Thermal-Gromit Works (www.tgworks.com) were presented at the conclusion of the contest. A Model-Down alarm was won by Joseph, who then gave the prize to Al so Al wouldn't have to spend so long out in the weeds next time. Jonathan Bryan won a 110 mAh Battery Pack for one of his future planes. Covering tape and hinge tape went to several folks whose names I've forgotten to write down. SURVEY Now the survey part: 1. For August 19th 2000, we'd like to get as many folks as possible to show up for the event. I'm curious how many HLG pilots there are in the Pacific Northwest, and what it would take to get them to come to Seattle? 2. In 2001 the Seattle Area Soaring Society is planning to hold a 2 day HLG event, likely in mid-August. What would it take to get folks from all over to come to this event? i.e., ask yourself, what would it take for me to drive/fly all the way to Seattle? Please send my your thoughts on these items and I'll compile them and send them on to the SASS 2001 2-Day HLG Events Committee (me and my dog Aileron).

[RCSE] perception of distance, hlg height etc
but overestimate actual positions (thinking we're further away in terms of being over a landmark, than we actually are) Scobie, Yes, I also tend to over-estimate the plane's distance away from me. The shadow cast by the plane can sometimes be useful in this regard as an indication of exactly where the plane is in relation to the ground (of course the relative positions of sun, plane, and ground have to be considered). If Chuck Anderson is correct that larger planes cause the opposite perceptual error, there should be a particular plane size in-between whose distance away we can accurately guess!
