[RCSE] Sagitta XC
To all, I think that this topic has been batted around several times on many occasions over the years. After much hemming and hawing, I have finally decided to build that Sagitta XC. I think it will be the perfect ship for the LSF Level IV & V tasks I have ahead of me. I am building entirely from scratch, so I have the opportunity to change some things during my adventure. Here are some of my expectations for the XC. 1) Light and strong, I would like to get it at or under 8 lbs. 2) Some hands free time while sloping. I do not want to have to fly it continuously while doing an 8 hour slope flight. 3) Lots of room for batteries. 4) Per the design, good XCountry performance for that 10K goal and returns. 5) I like to build in wood - Good performance from a wood glider. Questions to answer - - I don't believe the XC is a glider that will zoom but can I, should I, make the spar stronger? I have never actually seen an XC launch but I have heard tails of it breaking winch lines. Does that mean that the spar construction is strong enough? - Is the E205 beyond its time? Should I pick a more up-to-date airfoil like an SD7037 for a wider lift and speed range? - Are the wing rods sufficient? (two 5/16" rods through the fuse and only 3" into each wing seems wimpy) - Are the ballast tubes in the wings a good or bad idea? Here are the things I think I should improve from what I have heard over the years - 1) Lighten up the wings with lightening hole through all of the ribs - hollow out the tip blocks - carbon tip joiners - hand selected balsa using lighter weights as I build out to the tips. 2) Bellcrank type elevator controls ala Harley's Genie, removing some of the cable slop. 3) Remove the rudder balance and use pull-pull cables, (larger rudder?) 4) Keep the lead edge of the horizontal stab more blunt with the stab overall fatter for better authority. Any advice you guys can give would be appreciated. Best regards, Michael "Augie" McKibben AMA 716126 LSF 7720 - Level III [EMAIL PROTECTED] RCSE-List facilities provided by Model Airplane News.

[RCSE] Sagitta XC
Thanks to all who responded to my question. It sounds like many of wrestled with the plan form of the XC. I am not looking for world class performance, just a little better performance with some room for over speed errors. BTW, does anyone know what that "red-line" is for the XC? Do I have to use spruce for the lead edge or can I go with a nice hard balsa? I guess I have made most of my choices for improvements. 1 - Fill the void in the main spar with hi-load 60 foam. 2 - Wrap the main spar with Kevlar thread, paying particular attention to the joiner areas. 3 - Sheet the center section of the wing (seems like a damn shame though). 4 - Do whatever I can to lighten up the tips. 5 - Lengthen the tail moment by 4 to 6 inches. 6 - Use an airfoil shape on the stab - Tom Kallevang, did you do some kind of rib/spar lay-up for the NA0009 or try to sand that shape into the existing construction? 7 - Remove the rudder balance. I will make the fuse from wood (sounds like it needs some weight anyway) and use the cable for the stab. I don't see a good way to use a simple bell crank for the stab.

Re: [RCSE] Soprano Feedback
Jim, I have one of the Isthmus Model's Sopranos. I have flown it about dozen times. I am extremely happy with it. Launches hard and has great legs. I can slow it down for thermals and put the nose down to get out of dodge. Mine came in at 50 oz. I have not tried it with ballast yet. It is not a floater, although you can slow down to thermal, it flies more like a full house ship. The spoiler is very effective and it spot lands nicely. It is turning out to be one of my favorite gliders. Great launches, great penetration, fast, reliable, and durable. My opinion only, the Soprano gives a pilot more options for a wider range of conditions. I am looking forward to many more flights. Up in Minnesota, we have had 75% of our days with rain. - Original Message - From: "Jim Laurel" <[EMAIL PROTECTED]> To: "rcse Yahoo" Sent: Thursday, June 09, 2005 12:55 AM Subject: [RCSE] Soprano Feedback > Ok, so who's flying a Soprano out there?

[RCSE] Compu-FoamCore / Genie Cores
To all, I want to give a well deserved plug for Les' cores. I just purchased my second set of Genie cores from Laszlo Horvath (Les). Both of my sets and others I have seen are superb. Best value I could hope for. I will need almost no prep (no sanding) to get things going. Just stick 'em together and go! And they come packaged as meticulously as they are cut! If I factor my time to make templates, purchase foam, cut the plan forms, my 4 to 6 or more blown cuts until I get the heat just right and the sanding needed to make the marginal okay, I am miles ahead with Les' cores. PLUS! They are perfect, repeatable and he sends then out right away. So.if you are planning a winter build that requires you to cut your own cores, consider giving Les a call. Order two sets! He will save you time and money in the long run. Have a great building season! Augie Doggie RCSE-List facilities provided by Model Airplane News.

Re: [RCSE] Res....Again
Glenn, I bought a Soprano from Mark late last fall and have been waiting for the thaw ever since. They are beautiful, great lines and excellent construction. I had the luxury of getting to fly Mark's Soprano a half dozen times last year. That sold me right then and there. Launches high, wide speed range, can cover a lot of ground. The MH32 flies a little faster but I didn't find that a hindrance. I am still waiting for the thaw!

Re: [RCSE] Buiilt up RES ship...
Doug, How about a Mirage! Isthmus Model Company http://www.isthmusmodels.com/product_info.php?cPath=21_27&products_id=111 There is information for improved strength in the spar and adding a spoiler / wing bolt. One of the finest built up nostalgia glider ever designed...IMHO My last one came in at 31.5 ounces 113" span I flew it last weekend in gusty wind up to 19mph with 20 oz of ballast and it flew superbly.

"Brent" Sorry about the Doug... Also, Isthmus Models is coming out with a two meter Cara. Built up with CF tube spar. Hard launches & very wide speed range. Flew it in the same winds as the Mirage and it spec'd out several times while moving around the sky like a moldie. Best 2 meter I have ever flown...no lie.

[RCSE] Re: Harley Michaelis' Genie Line of Sailplanes
For some reason my links were changed in my email. Here they are again and should be working. http://www.geniebuild.com/ http://www.geniebuild.com/harleys_genie.html Thanks you, Augie - Original Message - From: Augie McKibben To: soaring@airage.com Sent: Wednesday, August 06, 2008 8:15 AM Subject: Harley Michaelis' Genie Line of Sailplanes Harley Michaelis is one of those rare individuals in RC soaring community that is both innovative and generous. By continually refining and sharing his designs over the past 30 plus years, whether through magazine articles, his long standing web site or participating in the soaring community's on-line conversations, he has made immeasurable contributions to the world of RC soaring. A couple of years ago, members of the local club I belong to asked if I would like to participate in a club build of the Genie. Admittedly, I had no experience with Harley's Genie, full house gliders in general and little experience with bagging wings. I had always been a proud and staunch wooden model builder. I agreed to take on the challenge and during the process of researching and building the Genie found a hidden love for the model. The design is well thought out from nose to tail with lines that are both distinctive and graceful. As I learned to build my first Genie and then the second and now on my third, I have kept in touch with Harley, asking questions and getting advice, hopefully getting a little better at building each time. Harley has been an inexhaustible source of advice for me. As I learned to fly my first full house glider I became more enthusiastic for the Genie. And when my second Genie (a Genie Pro) finally moved from the bench to the field, I was hooked. Right then and there I could not imagine flying another glider. A few months ago, I had started a web page to follow my third and eventually fourth Genie build http://www.geniebuild.com/ to share my build experience and help promote scratch building in general. These pages will go up and down as projects are started and completed. Just as this summer was getting starting, Harley and friend Mark Miller (Isthmus Models) had inquired if I would be interested in taking over the task of sourcing parts and putting together parts packages for those glider guiders that want to build one of the Genie line. Flattered that Harley trusts that I can effectively and faithfully carry on supporting and promoting the Genie line of sailplane, I have accepted. I will be sourcing and shipping the full line of Genie parts, plans and instructions, while maintaining the web site and on-line pdf's at it's new address http://www.geniebuild.com/harleys_genie.html.
