Item Description
Designed to handle the additional power and torque of 32-40 class engines, the Caliber 4 features a range of upgraded components over the Caliber 3 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.
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.
