Century® Radikal G20 RC Helicopter Features

The rotorhead is constructed of a CNC machined metal yoke and reinforced heavy duty plastic blade grips.
Floating style feathering shaft with triple bearing support including thrust bearings.
CNC machined, full ball Bell-Hiller mixer lever.
Adjustable Bell-Hiller mixer to achieve the preferred mixing ratio.
Stable main rotor blade grips with 5mm rotor blade bolt(HD version) or 4mm rotor blade bolt (LT version).
Blade holder with 14 to 18mm width allows the use of rotorblades from 12 to 18mm blade root.
29g aerodynamically balanced flybar paddles for sport and 3D aerobatics.
10mm hardened rotor shaft.

Electronic CCPM with three servos.
Electronic CCPM 120° configuration.
Push / Pull hinged double ball-bearing bell cranks.
Double ball-bearing pitch levers.
Plastic pre-molded pitch compensators for proper linkage positioning.
Double ball-bearing, CNC Machined Swashplate center with reinforced plastic out control linkages for 120°.
The swash plate is hinged with three servos to support 120° CCPM.
The control servos employ a push/pull system ensuring all the power is transferred to the swashplate in a unilateral direction.
A total of 28° pitch range.

Various gear ratios possible.
Spiral cut main gear provides additional contact service area for maximum load bearing and quite gear operation.
Sleeved autorotation main gear and hub with adjustable backlash.
Stable 15x24mm clutch bearing support by ball bearings.
One-stage gearbox offers the best minimal friction loss.
Constant driven tail rotor.
Heavy duty automotive grade belt driven tail is more crash resilient and lower cost.

Extremely stiff G10 or Carbon Fiber main frame with CNC machined bearing blocks.
Carburetor fuel level located at centerline for smooth engine operation in all flight attitudes.
Large 300 ml tank for long flight times.
Separate front and rear frame allows lower cost and easy replacement.
H-Frame with cross member design offers reinforcement in all three axes.
Extra long front trays offer convenient access to secure electronics.
Heavy duty low profile high impact-resistance landing gear accommodates hard landings.
Engine plate is CNC manufactured from a single piece of aluminum.

Triple bearing supported tail blade grips including thrust bearing.
140° of tail pitch range offers extremely fast tail response.
Triple ball-bearing supported hardened output shaft.
Integrated vertical fin into gearbox offers rigidity as well as weight reduction.
Tail boom mounted tail rotor servo for minimal slop.
Straight carbon rudder control rod offers maximum direct control.
Ball bearing tail rotor pitch bridge for linear tail rotor control.
Hollowed out attractive horizontal fin offers weight reduction.
Extra large 5×13mm bearings in the tail rotor gear box output.
Sturdy 25mm extra lightweight tail boom.
Tail boom struts made of lightweight aluminum.
Impact-resistant and lightweight 4.5g 95mm tail blades.
Hardened tail rotor shaft.
The tail servo is mounted right on the tail boom, thus there are no corrections to the rudder control linkage during disassembly of the tail section.
