Polyclub

The Polyclub is a radio-controlled aircraft that weighs an average of 250 grams.

Created in 2006 within the indoor club of Saint Vrain in Essonne, the original drawing is William Rohmer (willmodelism) member of the club at that time.

I wanted to make an indoor plane resistant to shocks inevitable when we start. At the time, the indoor planes were in balsa or depron. There was nothing really crash proof.

At the same time, I practiced slope flight (in Brittany) with the first aircraft in EPP (Combat air Model). These models were designed for flight uphill combat.

Why not transpose this principle for indoor ? The first indoor plane in EPP was created.

The name Polyclub was given by Jacques Rousseaux (currently vice-president of the FFAM and in charge of the regulation), present the day of the first flight to the club. Faced with its immediate success, the aircraft was subsequently copied by many manufacturers.

Electrically propelled model , it consists entirely of EPP in its official version mainly sold by the French Federation of model aircraft in France and other specialized stores. Its lightness and ability to fly and its resistance to crashes make it a powerful device. He is also in good condition to learn indoor model aircraft , he turns in a pocket tissue and does not fly too fast if the weight is not too high.

The Polyclub has become the official indoor flying school of the French Model Aircraft Federation. It has allowed many beginners to evolve to more complex models and thus join the world of model aircraft successfully.

Dimensions

  • Wingspan: 100 cm
  • Length: 75 cm
  • Weight: 200-270 g according to equipment
  • Wing area: 17 dm 2 , wing load 14- 16 g / dm 2
  • Radio: 3 ways minimum, drift, depth and gas.
  • Micro brushless motor (DYS A2812, 220 rex, DIY CDROM, micro typhoon, etc.) with appropriate controller and with GWS propeller of 10 × 4.7, 9 × 4.7, 8 × 4.3. Servo type 9 grams.

Description

This aircraft is cut with a numerically controlled machine and has few parts. It is made entirely of EPP, a revolutionary foam for model making. This material is unbreakable, elastic and memory shape: it cash shocks by deforming, without breaking and resuming its original position.

The radio elements are either double-sided on the fuselage or easily embedded in the EPP by digging the housing with a cutter.

The battery is fixed under the fuselage with one end of elastic and two pins. Very convenient to refine the centering The empennages consist of EPP cut out sheet.

The control ducts are glued on the epoxy fuselage for 5 min or embedded in the sidewalls. The fuselage is in one block. The engine is attached to a piece of plywood or epoxy glued to the nose of the aircraft.

Depending on the type of motor used, the fixing will be different. But the principle remains the same. The wings are EPP density 20 kg / m 3 .

The panels are epoxy glued 5 min. and the dihedral is already provided during the cutting. A 5 mm carbon tube takes place in the furrow to stiffen the wing. This tube will also be glued to the epoxy.

Flights are uneventful, the plane hovers very well. He turns in a handkerchief and is very responsive to the controls. With a brushless motorization the flights are more muscular.

It’s a treat for the eyes. A little wind and it flies hover, moreover it can even fly to the slope. For decoration the choice is vast because all the paintings work on the EPP.

Theft

Suitable for indoor and beginners, the flight is slow and stable, very easily controllable despite its 2 axes. The walls that are getting closer are no longer frightening. We like to fly it on a gas net. Its natural tendency to gain height when pushing the throttle makes it easier to take off. It remains more right when driving (a simple back pad is enough). The correct setting of the engine breaker must allow hovering gas cut with a slight downward slope. This setting is normally that of cutting the nose. Do not try to compensate for its tendency to rise

When you turn on the gas by increasing the breaker. It is better to drive the full throttle by pushing a little. This is especially noticeable for large engines chubby. The polyclub can also fly outdoors, even with a little wind.

Making a small stationary facing the wind is a treat. The basic stunt passes well, loop, reversal. Some spend the flight back (not long) thanks to a powerful engine. In short, a machine to have fun without making head.
