450PLUS CCPM / ARK-4500

(ARF 85% Assembled)

Box Size: L40xW18xH10cm

 

For enormous 3-D potential from a micro electric model, any ARK All New Series helicopter is a smart choice. The 450 Plus -- the ultimate Plus machine -- has the precision and polish to reach performance extremes. Highly optioned the 450 Plus challenges big, glow-powered helis for smoothness, stability...and the ability to accomplish seemingly impossible maneuvers

Features:

• 85% factory assembled
• Precise eCCPM control system
• Lightweight fiberglass site frame
• CNC Rigid, lightweight aluminum frame
• 3D efficiency fiberglass main rotor blades
• Efficient, quiet, belt-driven tail rotor
• Full ball bearings
• All-metal rotor head with thrust bearing
• Aluminum 120�X swash plate
• Aluminum boom
• All aluminum tail gear case
• Aluminum tail boom brace terminal
• New design fiberglass horizontal stabilizer and vertical stabilizer

The 120�X CCPM control system groups the three control servos (elevator, aileron, pitch) 
close to the main shaft. This allows for direct linkages (no bellcranks) which reduces slop and provides precise control of the swashplate. Collective pitch control is provided by mixing commands to the three servos. This is done electronically in the transmitter, therefore eliminating the need for on-board mechanical mixing.

The 450 Plus all-metal main rotor head features a responsive 120�X eCCPM control system. Control arms and mixinglevers include ball bearings for smooth operation. A machined aluminum swashplate adds precision.

Perfectly suited for brushless motor systems, the model's aluminum frame provides rigidity without unnecessary weight. The 450 Plus is autorotation-capable, with a driven tail for total control.

Micro servos, such as ARK SD109P (SD109P) are recommended. 450 Plus linkages are direct for strength and use ball links on both ends for easy adjustment.

The 450 Plus helicopter's all-aluminum tail gear case includes ball bearings on the driveshaft as well as the idler pulley for the smoothest operation. The belt drive system is strong, efficient, and quiet. A new pitch slider offers precise rudder control.
