265MHz UHF frequency transmitter is made up of V1 and external components C1, C2, L1, L2, etc. through the loop antenna L2 to the air-launched. L2 antenna use  silver-plated wire of the enameled wire diameter of 1.5mm. Antenna size is 24mm (long) X9mm (H). V1 Selection of high-frequency triode  BE414 or 2SC3355.

Part of the Radio-controlled Receive, Working voltage of 6V, waiting for the 1mA current. Receive frequency of 265MHz.

Receiver circuit primarily by V1, IC and other components, V1 and C7, C9, L2 components, such as ultra-high frequency receiver circuit. C9 to change their receivers to fine-tune frequency, so that strict firing frequency at 265MHz. Antenna size is 24mm (long) X9mm (H). V1 use BE415 or 2SC3355. Capacitor C9 may choose to use a small adjustable capacitor. IC use LM358.

All resistors use 1/8W or 1/16W Metal Film Resistors. Electrolytic capacitors are also used ultra-small capacitance. All other capacitance use high-frequency ceramic capacitors.
