Exact limits depend on the kit, materials, and local regulations on maximum takeoff weight and flying sites. - What’s the difference between a Chinook RC helicopter and other twin-rotor models?
A Chinook uses a tandem layout (two main rotors in line, counter-rotating) and controls yaw/pitch/roll by differential collective and cyclic mixing. Coaxial models stack rotors on one mast and rely on different mixing; single-rotor helis use a tail rotor for anti-torque. - Is it hard to fly a large scale RC Chinook?
It’s demanding but manageable with preparation. The airframe has more inertia and complexity, so start with simulator time and smaller models, then move up. A solid flight controller, good governor setup, and careful preflight routines make a big difference. - Which materials are best for building a durable large scale RC helicopter?
Carbon fiber or G10 for frames, CNC aluminum for heads/shafting, composite or fiberglass fuselages, quality hardware (hardened shafts, proper dampers), and rubber isolation for electronics. These balance stiffness, weight, and vibration control. - How does the Chinook compare to other large RC helicopters like the CH-53?
Both are heavy-lift icons, but the Chinook’s tandem system removes the tail rotor and relies on differential mixing, increasing setup complexity but offering broad, stable lift.
