Re: [RCSE] Limits in R/C Soaring - a proposed discussion
Don Harris had a 3 1/2 hour flight at the first Wood Crafters event in 2002. WC has always had the Longest flight event and what makes it work is the entries are limited to one entry per ch. This allows pilots to fly at will. Other Woody contests in the east have had the same task. I think it is a neat event to get LSF Achievement duration goals completed. The Woody only 2005 New Years Postal contest task is the longest flight... SOAR's Richard Burnoski and Eric Stenson have entered this year's Postal.

[RCSE] The proper way to add washout/twist...
Hi folks, Just curious if anyone knows how washout should be properly added to a wing. I don't mean how much should be added (that I understand fine), but rather how the wing should be twisted. Do you rotate the tip section about the 1/4 chord point? Do you rotate the tip section about the LE? Does it really matter?

Re: [RCSE] The proper way to add washout/twist...
The 1/4 chord point would be the best choice. But it's not that big of a concern usually. If you're cutting a foam core, then yes. Rotate the tip template around the 1/4 chord point.

RE: [RCSE] The proper way to add washout/twist...
Thought so, and that's what I'd usually do. This time I'm doodling a little flying wing that has twist from 1/2 span out, however, and having a straight LE would be helpful as a reference. Any guesses as to what doing this rather than twisting at 1/4 chord would do?

Re: [RCSE] The proper way to add washout/twist...
Twisting around the LE will add a bit of a pitching moment. Usually. However, a flying wing USUALLY will have a near-zero pitching moment airfoil so it's a non-issue. Besides, if it's a foamie, just twisting it with you hand and applying a heat gun, will usually twist around approximately the 1/4 chord point. So it's no problem. Really I've done it dozens of times. Don't sweat it. Bill Swingle RCSE-List facilities provided by Model Airplane News.

RE: [RCSE] The proper way to add washout/twist...
Not an EPP foamie (bagged composite), so I have to make the decision before I cut the cores, but I'm sure it'll work out fine. I'll throw in an extra 1/4 degree of twist (it requires 4 already).

Good thought from Al, in case anyone was following this.

Adam, Just curious if anyone knows how washout should be "properly" added to a wing. I don't mean how much should be added (that I understand fine), but rather how the wing should be twisted. Do you rotate the tip section about the 1/4 chord point (typically how I've done it in the past)? Can you rotate the tip section about the LE instead without changing the effect very much? Does it really matter?Just a thought: you should twist it about the hingeline of the controlsurfaces. The hingeline becomes a straight line, which simplifies thehinge and the seal of the surfaces. This way, you maximize the seal(or at least minimize the complexity of the hinges and seals) for thecontrol surface. Leaking pressure from the bottom of the wing to thetop of the wing (reducing aero efficiency and control powerefficiency) is usually a bad idea...Reimar Horten always did it that way.

Re: [RCSE] First Sailplane
I had a GL but never really learned to fly on it. I found out that you really need more than one or two rubberbands on the wing when you have a stiff up-start. I built a HOB 2x2 that summer. I still have the 2x2 but most of the original wood is gone! Both were flying with a Cox Sanwa 2 channel, 2 stick rig with dry cells. Sorry, my first tx was fully proportional.

[RCSE] Will build one Genie LT/S for resale.
Guys I'm about caught up with my projects with nothing much left to do this winter except build a Genie Pro wing once I see a set of cores. I rarely build except for myself, but would consider building one Genie LT/S for resale. The LT/S, as I build them, is not suited to rapid production. I work liesurely and carefully at my own pace. Figure a couple of months once we have agreed otherwise. I want no money until it is ready to ship. I would want the recipient to be someone deeply and seriously involved in traditional thermal competition, who likes to launch and fly aggressively, who butts heads with top competitors and who is competent to confidently fly high perfomance ships. Tell me about yourself, where you fly and about your equipment, so I can pick someone I would consider a good partner for this ship, who will appreciate it and not consider it dispensible like some other ARF. I'm not interested in selling to anyone who just happens to have the money to buy it. Price below is fixed and a fair one for time and materials involved. A larger offer means nothing to me. I can't guarantee perfection, but would build more carefully than I would for myself. I would want you to provide six suitable servos for me to install for you. I would do that and complete the wiring harness as part of the deal. I would need a switch harness and four servo leads with connector to use on the receiver side of the harness. I would need two servos for flaps with full length leads attached. Aileron servos will be soldered to the harness at the servo end. Servos would be installed using Mark Drela's cantilever mounting system in which servos do not touch the skin. I would install my all-internal Rotary Driver System using the Kimbrough Products couplers with my own custom made shafts and pockets. I would use tempered aluminum coupler tops on the flap servos. I only have JR receivers now and am best set up to deal with JR micro servos. 341's are fine for all applications except flaps. For those, 351's are just fine. I have some 368's in a big Genie, but consider them overkill for the LT/S. Maximum thickness is 1/2, but I do not want those thin wing servos for which there is no RDS adapter to fit the output gear. You can see pics of the LT/S in File 10 of the Genie pages at http://genie.rchomepage.com/. Some are in the Gallery file. I have many others I can e-mail. File 1,2 and 3 detail construction. Look over these files to be informed. Once I have decided on a buyer, assuming I get one, we can talk colors and trim. Glassed over LE's come with a glossy painted finish. The only tape used is the reflecting type. Price will be $845, your servos and RDS installed. A comparable moldie would cost you another $500 or so. Figure about $60-$70 to ship. US only.

[RCSE] SNOW/ planes for sale
Yes that four letter word. Well most of the parts have arrived for my 4th CNC machine. So it is time now to think of building at least during the week. Perhaps someone in a warmer section could benefit I finished off my fourteenth Bubble Dancer and have been flying it the longest of any that I have built.I had flutter problems with the previous two by allowing the stab mount to have a loose hinge. With this one I got rid of the problem. Phew!!! Unfortunately when I launched it I knew it was not quite as strong. After some research I found the green Amoco foam was no longer made by Amoco and the 45 # compression had now dropped back to 25. It will still take a very powerful launch from most winches. So now it is time to build another with Dow hi load 60. The unit is covered with glass only no paint so the carbon is very visible. It is equipped with 2 metal gear Hitec 85, no spoilers and an FMA M5 (ch11) receiver and a high capacity battery. Flying weight is approximately 39 ounces. The foils are the AG24,25,26 that Mark designed specifically for the application and in the write up has my name on them. Sale price $550 plus shipping. It will be ready to fly when you receive it. The other plane that I was trying to wring out the flutter was a Supra clone. Again the fault proved to be the same. It seems to be standing up well to my F3B winch. In order to iron out the difficulty though I switched to a thicker wing the SD7084 that Donovan of Selig Donovan said could race with the RG 15 at a slightly heavier loading. The interesting facet I find with this model is similar to my use of it years ago in the Magic by Weston it can pirouette on flaps in lift unlike others that I have flown. The planform is similar to the Aegea with the forward sweep of the Supra. A case of making good use of your mylar. The unit is equipped with four digital thin wing servos by Hitec and a Multiplex micro digital for the elevator an d a Futaba 133 for the rudder. All up weight 75 ounces. The receiver is a Multiplex IPD on 51 driven by a high capacity battery. The top surface of the wing is white with a pink tip diagonal . Of course this flies more like one of Harley's. So now having gotten rid of the flutter it is time to build it with Mark's thin foils again. Sale price complete ready to fly the day it lands $750 plus shipping . Finally I have a 3m Laser with Multiplex digital servos in the wing and JR 341 for the stab and rudder. A new high capacity battery drives the Airtronics FM receiver. The Fuselage is natural Kevlar with white wings on the top and carbon black on the bottom. The fuselage was crashed once and excellently repaired. Sale price $700 plus shipping. I received this in exchange for assisting in programming an Evo. Because of this the servo assignment is the Jr order for all of the above. So if you are in the same boat I will sell an Evo(Synthesized) to go with any of the above. I have one Evo 9 $500 and an Evo 12 $600. You would primarily buy them at this price because you are interested in the fact they are preprogrammed. The Evo is one of the easiest radios to program but almost impossible because of our previous experience. It is that experience of flying a plane towards you for the first time. Ask for pictures.
