Usage Features:
The A-10 Thunderbolt II V2 boasts several features that enhance its usability and flight experience:
- Realistic Scale Details: Includes realistic rivets, panel lines, CNC shock-absorbing landing gears, removable bombs and rocket pods, and a scale pilot figure.
- Pre-installed Components: Retracts and flaps are pre-installed, simplifying assembly and enhancing functionality.
- Improved Electronics: Features upgraded dual Hobbywing 80A ESCs with an 8A BEC for bulletproof performance. Elevator and Rudder servos are upgraded to 23g metal geared units for better torque and control.
- Precision Landing Gear: The nose landing gear is redesigned to minimize play, ensuring straight and true tracking at high speeds. Large diameter bearings in the landing gear allow for smooth rolling over rough terrain.
- Enhanced Control: Increased elevator travel provides pilots with more precision and control authority. Pre-installed ball-linked control horns ensure accurate and precise movements.
- Robust Construction: Made from strong durable EPO material, contributing to its rigidity and longevity.
- Easy Assembly: Features a screw-together airframe and a "soft" connector design for the wing quick release system, significantly increasing reliability and ease of assembly.
- Battery Bay: Enlarged battery bay now accommodates two 6S 3300mAh Lipos, allowing for significantly increased flight times.
- LED Light System: Equipped with an ultra-bright LED light system for enhanced visibility.
- Canopy Latch: A robust canopy latch with an extended pin reduces the possibility of accidental canopy release during flight.
- Improved Tires: Features an improved, more durable compound for the landing gear wheels, extending service life even in rough field operations.
- New Trim Scheme: An updated, more attractive trim scheme compared to the original model.
- Safe Start ESC: The ESC includes a safe start feature, preventing the motor from starting until the throttle stick is in the low or off position.
- Adjustable Control Throws: Suggested control throw settings for high and low rates are provided, allowing pilots to adjust for personal preference and maneuvering style.
Maintenance Features:
- Foam Repairs: Repairs to the foam should be made with foam-safe adhesives such as hot glue, foam-safe CA, and 5min epoxy.
- Spare Parts Availability: A comprehensive spare parts list is provided, allowing for easy ordering of replacement parts if components are not repairable.
- Pre-flight Checks: Regular checks are recommended to ensure all screws on the aircraft are tightened, especially the spinner, before every flight.
- ESC and Motor Maintenance: The motor and ESC come pre-connected with correct rotation. If rotation is incorrect, two of the three motor wires can be reversed. The ESC has an optional brake setting, which is off by default, and instructions are provided to switch it off if accidentally activated.
- Battery Management: Recommendations for battery selection and installation are provided, emphasizing the importance of using a battery with similar capacity, dimension, and weight to the recommended 22.2V 5000mAh 45C Li-Po to maintain the center of gravity.
- Flight Time Monitoring: Pilots are advised to monitor and limit flight time using a timer to prevent unexpected dead-stick landings due to low battery.
- Ground Range Test: Performing a ground range test before the first flight is recommended to detect potential control issues or radio interference.
