Issue Contents:
Steleto HQ 2.5/9 fuselages for 10″ root chords and spans up to 114″. Has S-glass Kevlar Epoxy construction. Extra reinforcement available.
Name of Layne/urwyler is changed to David Layne Designs. A new 130″ version is available with HQ 3.0/9 airfoil.
Cont: Tail boom can support V or T tail. Handles light lift well. Flies like a larger model.
Saturn 2.0 is similar to 2.9T model. HQ3/10 root 3/9 tip airfoils available w/ or w/o presheeted wings stabs. PVC-t6 Aluminum spar. Good design for
Automobile-towing models is evaluated. 900launches achieved with 1000line Visibility was a problem because of distance needed. Strong wings needed.
Pauncho suggests that the optimum CG can be discerned if the model when a gradual turn will not tighten. Other theories of model stability.
A device which holds the model and highstart in place on the ground while you get in position with your transmitter. For flying by yourself.
An optimum design for an RC Sailplane depends upon objectives. Equations for Panel Area and Aspect Ratio. Wing area is from sum of panels.
Internat. HLG Festival (Oct 94 San Diego) had 10 rounds of man-on-man comp. Different. Increasing flight times target flight times.
Launching technique: retrieving the model: turn off Rcvr first: landing approach is very important. Good article with some humor included.
Gordy visits the Fox family in Iowa for a flying session. Gordy describes Charlie Foxs Genesis flying wing project and describes how the models flew.
Traveler design is discussed. The model was for someone who might want to fly while on business trips. The model does most tasks ok. Good info.
Build light (ideas given)
Valuable information on making good contest landings. Plan to be at a spot and altitude at T-30 sec.
1/2″ foam carpet pads make a good wing friendly surface for a workbench. Krylon epoxy paint for fuselages. Bass Wood for leading edges recommended.
The design Essence by Alan Schwerin is discussed. SD3037 root SD8020 tip used in the model with success. Model has fences.
Author suggests that Graham Woodss observation that condensation occurs on the back side of the wing is to cooling rates/mass relationships.
Attributes of a good tow plane are listed. Large enough wing for visibility excess power rugged landing gear large fuel tank slow flying.
Plan for your contest by eliminating problems before the occur advertise in magazines and send out flyers. Keep a to-do list. Flying with a flying buddy provides competition which sharpens skills. Mark Nankivil is the feature flyer of the month.
Los Banos slope site is excellent. Cover photo shows DG-600 in flight over reservoir at Los Banos CA.
