This is the new and amazing Kyosho Caliber 4 Gas 1/10th RC Helicopter ARF (Almost-Ready-to-Fly). 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,CCPM (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! Features: - 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,CCPM (electric mixing system) realizes direct control feel and easy maintenance characteristics.
- Increased rigidity of the servo plate meets the demands of EMS,CCPM 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.
- Easy setting is permanently maintained with one-piece stabilizer bar, stabilizer blade and hiller control bar. Parts can be quickly 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 system 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 is obtained 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 belt drive system of the Caliber series is quiet yet while transferring precise power.
- 340cc fuel tank positioned at the rear of the frame maintains exceptional flight times. Clear fuel tank has easy visibility of the 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.
