IC U1 is a 3-function IC coded by a microcontroller. It works together with transistor Q1, Q2, and other parts of the RF transmitter. The IC’s pin 6.8.9 controls the code output of flying forward, turning left, and turning right instructions. The code is output to the 27.145MHz transmitter circuit via pin 13. Pin 14 provides a high level to Q2, Y1, C9 and L4, which generate the 27.145MHz frequency. Pin 13 outputs the code which is fed to Q1, R1, C4, and C8 via R4 for amplification. The code is then transmitted to the receiver via antenna C3, L2, and L1.
天線是使用51cm的拉桿天線。該天線是電感耦合。電池供電是由6個1.5V AA
電池。
The antenna is a 51-cm inductive coupling telescopic antenna. The device is powered by six 1.5V AA batteries.
When the remote controller is switched to “charge” position, U2, R30, and R31 will form a charging circuit. U2 is a regulating reference IC, charging the receiver via Q10 and R24. The charging current is 260 mA.
The signal is received by the antenna, coupled by C20, and amplified by Q3, R13, and R12. The signal is then delivered to the L1/C2 oscillation circuit via C4, frequency-mixed by Q1/C3/L3, forwarded to R3 and C8 via R2, and output to IC U2, which is a two-stage operation amplifier. After the two-stage amplification, the signal is output to U1 via R7. IC U1 is a 3-function IC coded by a microcontroller. It’s pin 2.5.6 controls the functions of flying forward, turning left, and turning right. Q4, Q5, Q7, Q8, R21, R22, R23, and R24 control the fan’s left and right turning at the rear of the motor. Q2 controls flying forward motor rotation. Q6 is for charging protection, preventing batteries from short-circuiting.

有的地方不一定對。xiaoDD的標點符號太亂了，看著糊涂。因為電路知識荒廢得太久了。
