Radio Controlled Soaring Digest December 1995 Issue
Issue Contents:
Instructions for mixing full house sailplanes using computer radios. Terms. are defined. Logic of flight modes are discussed.
The 2M Osprey kit uses foam core wing with optional configuration Schuemann planform S3014 wing 43 oz bolt on or 2 piece wing option.
Lasoar 1200 by Paul Perret is the winner of 94 and 95 Electric Nats. 139″ span SD7037 airfoil models for 25 and 40 size motors.
A poem “To Soar with Eagles” is presented. It is a poem written from the perspective of the eagle seeing R/c sailplanes.
Radio Glide is a the British Assoc. of RC Soarers BARCS contest. Middle Wallop was the 95 site. Coverage with photographs is given.
Part II of article on The Puma describes the fuselage and flying V tail. An alternate wing was made. Model weighs 10.5 oz. Cores are available.
Rather than a student being a receiver of an instructors verbal commandsa student learns by way of a small hand held R/c model to correct situations Level wings Fly model in a circle. Work on pitch control. Turns with pitch control. Later use of a training chord is highly advised.
Joe describes the elements of frustration which he has tried to eliminate or minimize. This enhances his enjoyment of the sport. Excellent Article!
Helping new flyers is important to clubs. Valley Aero Modelers have a contest format which has been successful for years with easy rules. Contestant chooses from three different tasks upon landing. Landing points = 25. List of contest turn offs. VAM club has AMA Award of Excellent.
Wing platforms are compared graphically for Falcon 880 Legend Waco 10-550 Falcon 550E Thermal Eagle Genesis Shadow. Data from MaxSoar data files
The Mistery Ship by Major Hobby is the first all laser cut wood kit. No composities used. 118″ model
1995 X-country and Pig Roast is described with photos and list of finishers. Pat Flinn from Mich. wins event.
Information given on spotting thermals. Clues include: seeing the models flight change seeing the thermal w/ blue blocker look for lift near sink watch for lulls in wind then go upwind fly toward shifts in wind direction recognize wave vs thermal lift.
The best spars provide bending torsional strength at minimal weight. Tensile strengths are given for E S-glass Aramid Carbon and Balsa.
Horizontal stabilizers can distort over time especially if one side is finished differently. Be sure to check for warpage with time.
Obtaining imported models is time consuming and expensive. Robin Lehman accepted the task of communicating with RCSD readers on the scale seen.
Most scale models come from Germany. Sailplanes Unlimited and Windspiel Models are the recommended ways to get imported models. Also Aero Towing.
Robin indicates that there is growing interest in aerotowing and scale. It seems the two may foster a needed symbiosis to allow both to grow.
Martin extends comments made by others at Elmira. Sailplane pilots were often modelers. Full size vintage planes were listed.
The full size International Vintage Sailplane Meet at Elmira NY had an RC aerotow demo. This is an account of the whole event with photos.
IVSM-95 demonstration of aerotowing is captured in cover and description on page 4. International Vintage Sailplane Meet. Robin Lehmans LS-4 shown.
