Objective and requirements: 1. Understand the flight principle and historical background of the "rubber-powered aircraft"
2. Master the debugging and flight skills of "rubber-powered aircraft"
Flight Guide: I. Inspect the Model
Looking directly at the head of the model, a well-installed model should be free from distortion and symmetrical on both sides.
Ii. Model Adjustment
When there is no wind or only a gentle breeze, hold the center of gravity of the machine head and gently throw the model out. Adjust the distance between the wing abutments front and back according to the model's flight attitude. Wavy flight indicates a light head, and the winglets need to be moved backward. A downward dive indicates a heavy head, and the winglets need to be moved forward.
Iii. Powered Flight
First, rotate the propeller clockwise about 15 times. Then, hold the machine with your right hand and support the propeller with your left hand, and gently push it out against the wind. Observe the flight path. A hovering upward posture is preferred. If you find that the model's circling radius is too small, make a small cut at the base of the vertical tail fin and then bend it in the opposite direction. After the flight posture is normal, make 200 to 220 turns around the rubber band to achieve high-power flight.
