100" Bighorn ARF - green 2,54m

The big aerobatic high-wing Bighorn plane proves a classic balsa airframe sporting large control surfaces, flap and powerful motor could bring you as much fun as “regular” 3D models. You can put a 50-70 cc petrol engine as well as 5-6 kW brushless motor with 12S LiPos in there - so it does not matter whether you are a high octane or high voltage fan. If you like what all those „Joke“ Pipers are doing in the air, but you prefer it really big, the 100” Bighorn is definitely a good choice for you.

Fuselage: The fuselage is of - now classic - ultra light design featuring balsa and plywood Kevlar®/carbon composite reinforced parts, detachable fibreglass cowl and large fuselage/canopy hatch allowing perfect access to the entire power system and RC gear. The engine or motor is to be fitted to a plywood/composite reinforced box using a radial mount.

Wing: 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 large ailerons and flaps are controlled by a pairs of servos.

Empennage: The empennage is a light all-balsa work; the two-piece horizontal tailplane uses a carbon tube joiner. The elevators are controlled by servos installed in horizontal stabilizer halves. The rudder is controlled by a pair of servos with a closed-loop linkage installed in the cockpit.

Undercarriage: The main undercarriage features carbon composite legs, f and lightweight balloon wheels; the tail wheel with an aluminium alloy bracket is coupled with the rudder.

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

RC Gear: You will need at least 7- or rather 9-channel RC set to control your Bighorn - the precise set-up of paired aileron, flap and elevator servos, optimized dual and exponential rates is the must for aerobatic flying. You will need 7-8 standard size servos (20-40 kg.cm torque) - you should go for high speed servos from the top of the mentioned torque range for 3D style flying.

Engine/Motor:There is a wide range of engines/motors you can choose from:

• A sporty trainer: 35-40 cc petrol engine like GP38, NGH GT35 or similar; it will work nicely with 19-20“ propeller.
• A sporty 3D/pattern aerobatic plane: 50-55 cc petrol engine with 22“ propeller.
• Brutal 3D aerobatic plane: 60-70 cc petrol engine like GP61, NGH GT65 or similar with 23-24“ propeller.
• A sporty 3D/pattern electric plane: 5 kW brushless motor like KAVAN PRO 8050-195 with 21x10“ propeller, 120-160 A ESC and 12S LiPo 4-6000 mAh.
• Brutal 3D aerobatic electric plane: 6 kW brushless motor like KAVAN PRO 8055-190 with 22x10“ propeller, 150-160 A ESC and 12S LiPo 4-6000 mAh.
