RC helicopters are by far the hardest to control and fly. Unlike planes, which rely on stabilizers and aerodynamic forces to maintain controlled flight, helicopters are totally at the mercy of pilots. Any mistake is immediately amplified, and can potentially lead to a crash. Setting up your RC transmitter is crucial for controlling the model and will determine its sensitivity to inputs and flight characteristics.
7 If possible, have a seasoned heli pilot supervise all programming changes and your first attempted flights. Use helicopter training gear to minimize damage in the event of a crash.
Enter your transmitter's main menu and locate the dual-rates/expo feature. Here you will be able to program the responsiveness and performance characteristics of the model. For beginners, it is crucial to add some exponential. This will soften response around mid-stick, and reduce the chances of a crash due to abrupt inputs.
