Re: [RCSE] First time foam wing construction questions
With a fair number of questions regarding foam and balsa wing construction I want to let people know that I have a page devoted to this type of construction on my website. I also have a number of HLG, slope/electric wings for sale on my Web Sale page. Some are completed and some are through the vacume bag. They are truly beautious!

Re: [RCSE] spining spoons Wind meter
Quite a while ago (and I can't remeber where), someone posted a link about making this sort of spinning windmeter that used a bicycle speedometer for the readout. It seemed pretty clever.

Re: [RCSE] calculating height using small angle formula
Here's what I came up with. Let's say my two split fingers are 1/4 apart 22 from my eyeball. I'll need an angular measurement for that so the circumference around my eye would be 2piR = 138.16. That divided by my 1/4 finger spread = 552.64. This must be converted to degrees so 552.64 / 360º = 1.535º. This is the angular measure from my eye to my outstretched fingers. Now the formula I got from http://www.astro.lsa.umich.edu/users/emiller/astro125/geom/geom.html#smallangle looks like this d = a / 360º x 2piR = aR / 57.3º. In our case d = wingspan, a = angular measurement, and R is the elusive distance to glider (altitude AGL if the plane is directly above our heads). So, solving for R, if my glider has a 100 span: 100 / 1.535º x 57.3 = 3732 or 311 feet. If I plug in your plane and antenna dia. of .34 and distance from eye = 26 we have 78 / 1.33 x 57.3 = 3360 or 280 feet. I did these over and over and can't find fault. This, however, does not mean I'm sure I'm right. I can't find any text with the formula you give. Can you point me in the right direction? Am I all screwed up here? Thanks, Pete --- [EMAIL PROTECTED] wrote: On Tue, 18 September 2001, Pete S. wrote: How do I solve for R? Assuming you are asking how to make a cheap rangefinder for judging how far away a glider is: Several convenient, no cost rangefinders are available to you now. The basic principle involved is that a small opject held at arms length can visually cove a much larger object at a distance. For example the Tx antenna diameter can be used as a distance gauge. There is some distance that allows you to just barely cover the wingspan of your glider with the diameter of the antenna. A no math way to do this is to have a buddy hold up the glider near a straight section of road. Then you just drive down the road a bit and see how far you need to go before the antenna diameter can just barely cover the wingspan. (hold out the Tx at arms length). You can do the same thing with other objects on the Tx such as the handle diameter. If you want to calculate the distances to get an idea of what kinds of range you will be working at you can do some small math as follows. distance_to_glider = wingspan / antenna_diameter * eye_to_antenna_distance The antenna diameter on my airtronics Tx is 0.34. The eye_to_antenna distance is 26. Wingspan is 78 So when the antenna just barely covers the wingspan it is 78 / 0.34 * 26 = 5965 inches which is 497 feet away. Be advised that the eye_antenna distance changes with angle of veiw. Horizontally for me it's 26 and vertically it's 22. Also on my Tx the antenna button is also 0.34 and if I point the antenna directly at the ship the eye_to_antenna_button distance is about 72. The distance that the ship would be at when the antenna button just covers the wingspan would be 1376 feet. __ Terrorist Attacks on U.S. - How can you help?

The hotmail is syncronised with OE, not downloaded. The difference is that when i check my mail in OE, I do not download the mails locally onto that machine. The machine is only syncronised with the hotmail. When deleting mails in OE they are deleted on the hotmail account. The OE syncronises itself every time I send and recieve mail. The hotmail is not dependant of the ISP. I have a own hotmail account just for RCSE. Go to hotmail and set up an account, it´s free. And set it up in OE.

Re: [RCSE] Omega 2M from Northeast Sailplane
Does anyone out there have any experience with assembly, setup and flying of the Omega 2M from NESP? I finished mine last night, and hope to fly this weekend. I reinforced the front wing mount and tied both the front and rear wing mounts to a long towhook block, since I want to try ballast. This arrangement should also allow the wing mount to carry more of the stress from the launch. (The rear wing mount has 1/4 plywood block under the wing. I did the same in the front, then added a simple plywood bulkhead that extends from where the wing plugs in front, down to the towhook block. I added a similar bulkhead under the rear wing mount.) Wing servos are a problem. The Omega 2M has thin airfoil and LARGE control surfaces. I used Volz Micro Maxx for the flaps, and HS-81MG for the ailerons. I had to grind away some rib area to make room. The servos are glued onto 1/32 plywood that is expoxyed to the wing. Servos are covered with MM Glidertech servo patches. The finished height of both sets of servos is about 1MM too high to mount flush with the wing surface. The produce a slight bump under the patches. I considered the new JR micro digital servos.

Well Barrett, how'd you like THAT speech? I agree GW was not shining in the beginning. Indeed, I didn't think it possible for him to come across as genuine and intelligent at all, ever. But even I have to admit THAT was a good speech. Let's hope that this is a new and permanent side of GW we are now seeing.

I am ashamed and sad knowing that we have Bush as our LEADER. Hearing Bush's words, along with all of the other leaders who are supposedly representative of our nation, and seeing the members of Congress struggle through a staged rendition of America the Beautiful made me feel like I'm a citizen of a second-rate power. I think there's a big difference between appearing to be unaffected and looking like an idiot, and simply appearing to be unaffected, yet pissed off and deadly serious. Bush, with his constant eyeblinking, mispronouncement of simple words and linguistic stammering, made me feel embarrassed and SCARED for our country, and extremely angry on behalf of those who have fought for the freedom and democracy that Bush has promised to protect. Let's review some facts... W is an inexperienced leader when it comes to world affairs = TRUE W is probably scared, just like the rest of us = TRUE What kind of leader issues 2 min. prepared statements and refuses to speak with the nation during this crisis? I was all for stand behind the President during our time of crisis but this guy is a wooden puppet. Freaking Guliani makes him look like a fool. They won't let him take questions because all it is going to take is one fuxored remark to the press to permanently shake public confidence that Dubya is up to the job. *I* know Dubya isn't up to the job, but Cheney, Powell and the DOD are. All I want from Dubya is to do his speeches, read off the cue-cards and be reassuring. Then I want him to get out of the way and let the adults run the show. It is our RIGHT to question whether Bush can handle this situation; it is his JOB to prove he can. This is the end of an era - of American innocence and (hopefully) complacency. We've been giving (and given) plenty of lip service about what sort of a dangerous world it is. Well, this is about as rude of a wake-up call as it comes, short of a couple of backpack nukes (I guess Osama couldn't afford those. Wonder if he invested in any dot-coms last year?) What does this all mean? I think a lot of my lefty friends are going to be bugging out about the rise of an American police state and about how a lot of personal freedoms will be compromised in the wake of these events. And to a certain extent, this will happen, but it's an inevitable compromise. Adolescence is over, folks. Time to grow up.

OK, I should really follow the thread, I read this about an hour ago and keep thinking about it. Was it: - The resurgence of cruciform tails. That was sure an interesting trend this season, quite an effective one for me and the flying I do. My preference has changed from not really caring about the tail much and ending up with a lot of molded Euro V tails to caring and ending up with US made cruciform models. Was it the the first euro moldie to go cruciform, the Scar, the molded Psyko for being there all the time, or the Icon for taking the cruciform moldie to a new level of design, the new top of the food chain moldie. I don't know, but they are back again, and I like it. BTW, another favorite of mine is the Schpot Dorker LT, again, made in the USA. Another trend this year was 6 servo wings, I almost bit as I had an Escape, but I sold it before I built it to help finance my Icon. - The development of the sidearm launch. This was a significant development, it completely changed the HLG contest scene. For me this meant putting HLG on the back burner this season as I didn't have time to obtain and build a new quiver of DLG along side a quiver of F3J models. But I got to meet Denny, and I bet he has even better things up his sleeve for next year. 8-) - The F3J stake issue. The most significant development here is so far the USA has handled this rule in the correct way in every contest I have attended. - Breaking the $1000 barrier for a competitive molded sailplane. Nothing new about this to me, that threshold was passed one or two seasons ago... - The popularity of RES. - Dynamic Soaring. Both were around last year, I am glad to see they are gaining popularity. I need to DS again. 8-) Jim Downers Grove, IL Member of the Chicago SOAR club, AMA 592537LSF 7560 Level III ICQ 6997780R/C Soaring Page at www.jimbacus.net RCSE-List facilities provided by Model Airplane News.

[RCSE] Tips on LE's and tips.
Hi guys. . .I have just finished up my 21st scratch-built GENIE. This is an original design, vacuum-bagged, thermal competition ship on which the prototype was built 8-9 years ago. See pics of a couple at http://www.proptwisters.org/genie/genie.html. While bagging the wing, I tried a couple of ideas not heard about before that those who still build may like to know about. As I have often done, I trimmed the cores for a LE of 1/4 harder balsa to shape to core contours. I then pre-glassed them using the 1 x .003 fiberglas tape I got from CST. I attached the tape with 3M77, brushed on bagging resin, smoothed it uniformly and let it cure. The next step is what I did differently. I wanted to protect the fine finish on the LE from being messed up during bagging to cut down on the touch up work. To this end, I found some 1/2 wide color-coded electrical tape (Action brand from National Tape Corp., New Orleans, item #7076A). I placed a length of this tape, sticky side down, on a long piece of plate glass, waxed the other side, then carefully centered it on LE. I positioned the waxed/painted carriers to extend about half way over the 1/4 LE. As hoped for, the excess epoxy and layup extended partly over the LE, but did not adhere to the waxed tape. After cutting off the unwanted overlap, I peeled the 1/2 tape off and to my great joy, had a smooth LE, free of pits, bubbles and unwanted epoxy, one like never before. With careful masking of adjacent areas, I feathered the layup to the pre-glassed LE, preparatory to masking to apply a painted finish to the LE. It looks nice! The other different thing done was this; I replaced a section of each extreme tip of the cores with sort of pie-shaped pieces of balsa. I ran the grain span-wise to get rigidity not provided by foam. These balsa pieces were shaped to match the removed pieces of core and to give a tip-like shape, birds-eye view. However, they ended with abrupt vertical edges, thus imparting no compound curves the carriers could not conform to. The carriers and layup were sized to end at the vertical edges. After bagging, there was a perfectly-painted layup to the vertical edge. After sanding the edges smooth, still in the vertical, a V groove was filed into the balsa edges. A finished, rounded edge was then created by pressing some of Taylor Collin's (Soaring Stuff) 2 part epoxy putty into the groove and working it to perfectly fill to the upper and lower edges of the painted skins. A strip of vinyl masking tape was placed on both painted surfaces at the extreme edges to keep the putty off the paint. This 2-part putty comes in a wiener-sized roll from which you slice off a piece to knead with thumb and finger to mix. The brown mix slowly hardens, giving ample time to shape with fingers, trim with Exacto or razor blade and ultimately fine-sand with wet/dry paper. The bagged, painted area was then masked to spray paint the putty to look integral. In appearance, the tips rival those of a molded wing. Harley Michaelis, LSF023, 26 S.
