JR Forza 450 Kit with Blades, Motor and ESC

The JR Forza 450 is an advanced 3D electric helicopter aimed to uplift the 450 class helicopter community to a new performance pedestal. Designed around a reputation for quality and built for the pilot who wants the ultimate in extreme 3D flight. JR took everything they loved about their big machines and reduced it into a convenient yet potent flybarless heli.

The integrated servo mounting points of the bearing blocks offer both solid servo location and a direct linkage connection to the aluminium swashplate. The servos are also very easy to remove. Adjustable aluminium (JR type) servo arms are included to provide accurate linkage geometry. The unique autorotation system features the one way bearing in the pinion gear, which simplifies the main gear while also reducing weight. The helical teeth main gear helps to keep the drive train smooth and therfore quieter. The large front pulley for the tail drive belt offers lower drag and the simple tail rotor control lever is slop free so you can have a bigger 3D heli flight experience.

Features

• Bearing blocks with integrated servo mounts - solid servo mounting and direct linkages to the swash plate.
• Carbon frames which are rigid and lightweight give a very clean look to the helicopter.
• The servos can be easily removed from the helicopter frame.
• Adjustable servo horns are included to provide accurate linkages. (Only for JR servos)
• 6mm main shaft, 4mm tail shaft - strong and crash resistant.
• Autorotation one way bearing integrated into the pinion gear, allowing a simple and leightweight main gear.
• Helical tooth main gear results in a smooth drive train and low noise footprint.
• The new belt drive system features a large front pulley, giving low drag drive to the tail rotor.
• Originally-designed control lever - very simple with no free play - feels like a much larger helicopter.
• FRP canopy neatly covers all the mechanics, giving a simple and smart appearance.
