About this Plan

Helio H-395 Super Courier. Free flight scale model, for rubber power or CO2. Wingspan 610 mm. Scale is 1/20.

Quote (google-translated): "Helio H-395 Super Courier, by Lubomir Koutny.

1:20 scale models sit at the 'mini' end of the scale modeling spectrum. At the other extreme are the giants - 1:4 or 'quarter-scale' models - while Pistachio, Peanut, and these 1:20 scale models occupy the smaller end of the range.

The 1:20 scale has many enthusiasts in the USA, England, Japan, Israel, Sweden, the CSFR, and Poland. This plan could help establish the category in Germany as well. The advantage of the 1:20 class lies in its size: the models are more robust than Peanuts, meaning they can be flown outdoors in light winds; furthermore, the slightly larger scale compared to Peanuts allows for more scale detail - or at least makes it easier to incorporate such details.

Incidentally, over 20 plans for 1:20 scale models by the designer of this Super Courier are available through English hobby publications. The Super Courier has enjoyed great success in various competitions. Although this category was originally conceived exclusively for rubber-motor power, the models are frequently equipped with CO2 motors. And - even though the designer and many fellow enthusiasts of these small aircraft consider it a breach of style, 1:20 models can also be fitted with micro radio-control systems. It works; a Super Courier has flown quite well with a CO2 motor and RC-controlled rudder.

The model is not difficult to build, looks attractive, and is great fun to fly. Being robust, the aircraft withstands somewhat rough handling - such as being launched by a child. In short, it is a plane for the whole family.

Construction: Before starting, gather some high-quality, very lightweight wood and a cutting tool for making strips. When selecting wood and adhesive, minimizing weight is the top priority. Aside from razor blades, the most important tools for construction are numerous very fine pins. These aren't found in department stores; instead, source them from specialist suppliers for indoor flying models or shops catering to insect collectors. Use the razor blades either whole or by snapping off shards to serve as cutting edges. Important: Since the 1:20 scale models are inexpensive, don't skimp on the razor blades - only the highest quality will do!

Cover the plan with clear plastic film and pin it to a flat, soft-wood building board. We begin with the fuselage. First, cut the longerons; then, assemble the two side panels using a pin jig, starting from the rear. While the lateral profile pieces on the formers and the longitudinal shaping strip can be attached to the left side panel while in the jig, the right fuselage wall requires freehand assembly - unless you build a second, mirror-image jig. Carefully sand the side panels, removing more material toward the tail to save weight. Align the sides precisely and glue them together at the rear..."
