Spectacular control unites with dynamic compact performance!
Specially equipped for 32-40 class engines and EMS.

The proven reputation of the Caliber 3 earned with beginners and intermediate fliers has been enhanced with even greater agility. Designed to handle the additional power and torque of 32-40 class engines, the Caliber 4 features a range of upgraded components such as high-geared transmission, lightweight 7g stabilizer blades, modified clutch drum, HG swash plate, ultra-quiet transmission and a high-flow cooling fan for efficient use of the extra power. In addition, to meet the requests of more advanced fliers, the Caliber 4 is specially designed with EMS (swash mode) as standard. The result is the compact size of a 30-class base, but with the performance and agility of a 50-class helicopter. For dynamic and easy to enjoy flight, there is no equal! 

• 40-class engine (sold separately) power unites with an enhanced Caliber 3 base to realize expert-level performance. (*Modification may be required depending on engine type).
• With flying performance at a level above, the Caliber 4 keeps the practical flying size and economic benefits of a 30-class.
• The swash mode (120 degrees) of the EMS (electric mixing system) realizes direct control feel and easy maintenance characteristics.
• Increased rigidity of the servo plate meets the demands of EMS functionality and produces more linear control.
• Features high-performance 7g lightweight stabilizer weights. Combines with high-gearing for sharp agility and control. Optimizes use of available power for advanced 3D flying.
• Optimal setting permanently maintained with one-piece stabilizer bar, stabilizer blade and hiller control bar. Parts easily replaced so your heli returns to its peak flying performance.
• Reinforced 1.0 module main gear and aluminum main gear housing extracts the maximum power from larger engines, which is transferred through a high-efficiency belt for the highest torque.
• Number of fins increased from 6 to 12 on the cooling fan to produce a huge increase in airflow. Efficient cooling of larger engine maintains high power output.
• Machine cut aluminum HG swash plate produces rigid control and high durability.
• Aluminum diecast clutch drum realizes improved clutch engagement with larger engines.
• Aluminum diecast engine mount provides rock-solid engine support and excellent heat dissipation.
• Precision stainless steel linkage balls for smooth movement and durability.
• High-efficiency promised with full ball bearing specifications that include a total of 43 ball bearings.
• Diecast aluminum muffler included as standard.
• Features a lightweight but strong one-piece skid and low-height brace.
• Compatible with most Caliber 30 optional parts. (Not all parts are compatible)
• Direct mounting of servo delivers improved tail control.
• The renowned two-stage deceleration system of the Caliber series with the belt drive at 1st deceleration realizes quiet yet powerful flight.
• 340cc fuel tank positioned at the rear of the frame maintains exceptional flight times. Clear type fuel tank has easy visibility of remaining fuel level.
• Slide block system and one-piece hiller control bar and stabilizer blades require no ongoing adjustment and make re-assembly easy.
• Adjustable stainless linkages enable precision adjustment.
