Issue Contents:
the model at the Mid South Soaring Championship. S4233 section was used. Featured is a strong D-tube which will take strong winch launches.
The results of the Entry Level Design Contest was discussed. Tyro design costs $76.67 Oliver Wilson of Pt. Charlotte F> designed built and flew
Hollow core wing Pt. I. A simple rectangular wing was selected from the Facctor design. Project was started making spider foam cores with vacuumbagged skins was used as a plug for the molds. Details are givenon how the plug was prepared.
CO7 design by Hans Jurgen is for F3B F3J competition. It is a sweptnarrow chord design carbon fiber spar composite construction.design has a higher sweep (25 deg)
Bruce covers experiments of design changes having to do with wing sweep tail surface size nose length to make handling and performance better.
Swift S-1 1.9 Meter sailplane has S7012 airfoil. Micro servos fit in the wing. 39 oz 457 sq.in.
Servo Cans for Airtronics 141 servos. 1 grams round ABS mounts in wingand allows easy removal of servos. $10/set
Foam based slope planes loose performance when they get dents in the foam. The Roughneck by Pt Bowman is made of expanded polypropylene foam (EPP).The new foam recovers from compression is resistant to chemicals UV resistant. Contact cement or silicone adh. is needed to attach things.Black Ultracote stuck to 3M 77 over the foam through heat and abuse. Instructions for finishing EPP foam models to do battle at the slope.
A memorable launch at the MSSC resulted in model safely crashing into a tent. The contestants first contest ended up being successful.
Comments on the 96 Nid South Soaring Championship including comments onthe XC Competition Banquet flights near the motel and Memphis sights.
Tall Barracuda fuselage permits landing with full flaps use of multiple wings are possible on flat sides of fuse. SD7080. Brian feel thatthe SD7037 is not optimal for normal sailplanes. It may be for light loadings. Wing platform is that of Ron Vans Spectrum 2M.
The first annual 2M Soaring Festival was reviewed. It was a 2 day contest with all the elements of an established national contest. Comments givencomments on Laser ARF Windstar. The development of 2M designs included Gnome Falcon 600 Banchee Super V Vaquero Barracuda 2M Laser.
Construction of the Krause ASW 24/27. Fuse is white gel coated but 2 lbs. About 2X of Viking fuselage. Details given on how to complete construction.
The M321 was the largest aircraft (glider) built in WWII. Brief historyof German Aerospace dev. DFS230 Gigant Gotha 242 References given.
First part of construction tips. Bagged FG skin wings perform better than wood skins. User friendly equipment and materials are more widely…widely available today. The method is now high mess not high tech. Preparing the cores and Mylar carriers Transferring paint and adding color.
The catapult launch of the Bullet Bird is most impressive and might be termed slope flying on the flying field. Details given on idea.
Problems of using TD tow hooks for aerotowing. A design is described which can be used to TD planes with almost no alterations to the sailplane.
Account of 1996 Canadian slope racing trip which was altered due to low wind Account of alternate HLG flying and international friendship.
Review of winglet use of full size scale model use. Benefits: higher lift low speed turns less tip stalls. Photos included.
