Vintage Scale — Triton Models (Greg Harding)

Triton Models is Greg Harding's company in Kotzebue, Alaska. You may have seen his ads for a 1/6-scale, 124‑in. span DFS Reiher. He has recently introduced a 1/5‑scale Kirby Kite.

Greg on Triton and himself:

  • He started the business a little over a year ago; it remains mostly part‑time while he flies full‑size airplanes (Cessna ag‑trucks converted to tankers).
  • His aim is to produce scale‑accurate kits that are as easy to build as possible. Fiberglass fuselages are used to simplify construction.
  • The Kirby Kite is a rare, attractive model; Dale Busque helped with the plans. Early buyers of the Kite were mostly customers who already owned Greg's Reiher kit.
  • Greg plans to expand Triton’s line of mostly vintage sailplanes. Upcoming kits mentioned: a 1/4‑scale HP‑18 and a 1/4‑scale Schweizer 2‑22.
  • He also offers fun items: T‑shirts (designs include “Real Sailplanes Have Gull Wings”), a pre‑WWII German NSFK decal originally made for the Reiher kit, and a 4.5‑ft. powered, radio‑controlled semi‑scale Goodyear blimp.

Triton contact and ordering:

  • New mailing address (company move to Pennsylvania): Box 103, R.D. 1, Reading, PA 19607.
  • Current hand‑printed brochure available by SASE.
  • Prices (as listed): Kirby Kite kit $230 + $12 shipping; T‑shirts $12; decal $5; blimp $49.95.
  • Note: Triton originally based in Kotzebue, AK; prices and availability may change (Reiher price was noted to increase historically).

Vintage Scale — Cliff Charlesworth (England)

  • Span: 3.75 meters
  • Suitable power: .45–.80 cu. in.
  • Performance: excellent under power and on the glide
  • Plans: three large sheets, price 16 pounds sterling per set
  • Cowlings and canopies available

Other quarter‑scale plans available from Cliff include: Ka‑3, Ka‑8, ASK 13, ASK 18, Grunau Baby, Hütter 17, DFS Reiher II, Olympia 2, DFS Meise, Lo 100, and Mü‑13.

Vintage Sailplane Association (VSA)

The Vintage Sailplane Association is the national organization for full‑size vintage glider enthusiasts. Many modelers join to follow full‑size events as well as modeling activities. Jack Hiner (SOAR club) is cited as Northern District vice‑president for VSA.

Thermal‑finding and low‑altitude tactics (practical tips)

Key points for finding lift and dealing with sink:

  • Thermals often break loose and drift downwind; thermals encountered at launch height frequently originated upwind of the field.
  • When low (a couple hundred feet), search above structures, tree lines, or hills with large open areas upwind — weak thermals drifting across open areas can be kicked off by obstructions and strengthen.
  • Look for sheltered areas (small valleys or among buildings) where air can warm without being blown away. Parking lots are usually poor candidates because the air is flushed through too quickly.
  • If the whole field cycles (all lift disappears and then returns), observe the pattern closely. On windier days you may still catch good air by launching immediately and heading downwind.
  • On calm days with large‑scale cycling: if forced to fly during a sink cycle, fly straight, far, and fast out of the bad air to reach better conditions.
  • Fly aggressively — actively search for thermals rather than waiting for them to come to you.

Note: These tactics apply to all sailplane sizes — from Two‑Meter floaters to larger "Super Ship" designs.

Futaba narrow‑band upgrade program

Futaba offered an upgrade program to meet AMA's narrow‑band initiative covering October 1, 1990 to March 31, 1991. Not all models are eligible; specific treatments varied by model.

  • AM transmitters: modified for narrow‑band output (some models can be switched to FM)
  • AM and FM receivers: exchanged for narrow‑band versions
  • Costs (approximate): $10 for an AM transmitter upgrade up to $90 for a PCM 512 narrow‑band receiver; common receiver exchanges ranged $35–$65

For exact details on particular sets contact:

  • Futaba Corporation of America, 4 Studebaker, Irvine, CA 92718

Airtronics 401 gear repair

A service was noted in a club newsletter: Pete Russell in San Jose will replace the plastic output gear on Airtronics 401 servos with a steel gear to improve durability.

Photos and contest notes

  • Bob McGowan won big at the Masters Soaring meet (photo captions mentioned Falcons in the Standard class — Falcon 800 and Falcon 880; Mark Allen's design noted as a strong recent competitor).
