59″ Challenger ARF – green

Description

The 59” Challenger, an aerobatic high-wing sportster, is an ideal model for skilled pilots who just want to have a little bit of fun; it would make a perfect first truly aerobatic plane for a weekend flyer as well.

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 PRO 4345-730 etc. with 70-90 A ESC featuring powerful SBEC). Detachable hatches on the top and bottom of the fuselage are giving perfect access to the entire power system and RC gear. The elevator and rudder mini 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 full span ailerons are controlled by a single mini servo each.
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 large diameter wheels; the tail wheel with a carbon bracket is coupled with the rudder.

You will need 800-1300 W brushless electric motor (e.g. KAVAN PRO 4345-730 with 14×8” prop on 4S LiPo or 13×8“ on 5S, 70-90 A ESC and 4-5S LiPo 2,600-4500 mAh at least 30C; you should go for 40C pack if you are seeking 3D performance.

You will need at least 4-channel RC set to control your Challenger, a good 6-channel (or more) radio is preferred to enjoy the independent set-up of aileron servos. You will need 4 strong metal gear mini servos – a Sunday flyer should be happy with Hitec HS-225MG; 3D fun calls for something faster and digital, like KAVAN GO-1035MG.
