The semi scale 1400 mm Decathlon by the OMP HOBBY is a perfect advanced trainer for 500-600 W brushless motor and 3-4S LiPo battery. Using 3S LiPo and small control travels makes it a great trainer for basic aerobatics and general “Sunday” relaxed scalish flying; or you can put 4S pack in and set large travels in order to enjoy some prop hanging and 3D fun.

The fuselage is of light balsa and plywood “box” design covered by the Oracover® iron-on film. It is prepared for installation of 500-600 W brushless motor using a radial mount (e.g. KAVAN C3542-1000, KAVAN PRO 3542-950, Model Motors AXI 2820/12 etc.) with 40-60 A ESC featuring a powerful SBEC. A detachable windshield and large hatch on the top of the cockpit are giving perfect access to the entire power system and RC gear. The elevator and rudder micro servos are to be installed into the tail end of the fuselage.

The two-piece all-balsa wing with a semi symmetrical airfoil uses a carbon tube joiner; the wing halves are secured with screws to the fuselage. The ailerons are controlled by a single micro servo each. The scale wing struts are secured with screws.

The empennage is a light all-balsa work.

The entire model is covered by the ULTRACOTE® iron-on film (ULTRACOTE® is the trade mark for the ORACOVER® film used in the USA.)

The main undercarriage features aluminium legs and lightweight wheels; the tail wheel with a carbon bracket is coupled with the rudder.

You will need 500-600 W brushless electric motor (e.g. KAVAN PRO 3542-950 with 13x6” prop, 50-60 A ESC and 3S LiPo at least 30C 2,200-3,000 mAh; you should go for 4S 2,200 mAh 40C pack and 12x5-6” propeller if you are seeking 3D performance.

You will need at least 4-channel RC set to control your Decathlon, a good 6-channel radio is preferred to enjoy the independent set-up of aileron servos. You will need 4 strong 12-13 g metal gear micro servos - a Sunday flyer should be happy with KAVAN GO-13MG; 3D fun calls for something faster and digital, like KAVAN GO-1013MG.
