In conventional radio controlled models, a receive frequency is changed with a changeover switch mounted in a receiver body. In the present invention, a frequency switching scheme, employing a radio system in which a transmitter switches the receive frequency, is provided. Using weak radio waves usable without authorization, the transmitter transmits frequency data set therein as a frequency switching signal to a receiver. In the receiver, the receive frequency is set to a predetermined weak radio wave frequency when the power source is turned on. Upon receiving the weak radio waves, the receiver reads the frequency data out of the set signal and stores it into the memory means. Thus, the frequency setting has been completed. When the receiver does not receive the frequency switching signal for a fixed period of time, it reads out the frequency data used previously from the data memory to start the receiving operation.

The invention discloses a security protection method for a remote control model aircraft, which comprises the following steps: firstly when a remote controller fails to send remote control signals to the aircraft within time t1, a first timer module produces a triggering signal, which is sent to the aircraft by the remote controller; secondly, when the aircraft does not receive the remote control signal and the triggering signal within time t2, the aircraft is turned off and at the same time a protection device for the aircraft is turned on. The invention also discloses a security protection device for the remote control model aircraft, which comprises a first timer module, a second timer module and an aircraft protection device. The invention also discloses a remote control model aircraft, which comprises a remote controller, an aircraft, a first timer module, a second timer module and an aircraft protection device. The timer module is adopted to realize the testing whether the remote control range is surpassed or not, thus realizing automatic protection and avoiding harms to the aircraft and human being.

An engine starter for a radio control model includes an output shaft concentrically connected to and synchronously rotated with a T-shaped drive axle of the engine to start the engine. A drive wheel is sleeved on the output shaft for receiving an extra power. A limit wheel is sleeved on the output and synchronously rotated with the output shaft. The limit wheel is selectively driven by the drive wheel. A gear box is secured on the engine and provided to receive the output shaft, the drive wheel and the limit wheel. A torsion adjust device is mounted to a free end of the output shaft after the output shaft extending through the gear box. The drive wheel is idle running when the torsion force from the engine is greater than that from the torsion adjust device for protecting the engine from a forced operation.

The present invention is a radio-controlled (RC) model aircraft system with laser tag capabilities. A transmitter and receiver are each installed in at least two separate RC aircrafts. The transmitter on one aircraft emits an infrared light beam to the receiver on the other aircraft(s) that changes the infrared signal to a first servo to move an arm, which releases a model aircraft door behind which there are ribbons. The ribbons escape from the aircraft wings to show a hit. An optional second servo operate a smoke screen and eject a pilot to simulate actual combat. The system may also include audio and lighting effects to simulate firing and hit sequences with accompanying theatrical, physical effects including release of smoke and ribbons, and ejection of the pilot that realistically simulates air combat.

The invention discloses a method for adjusting parameters of a remote control model receiver and a remote control model. The remote control model receiver is provided with an adjustment state signal judging module and an adjustment parameter processing module. The method is implemented as follows: judging whether a signal emitted from a remote control unit and received by the receiver is a preset adjustment state entering signal or an adjustment state exiting signal by the adjustment state signal judging module; taking received subsequent signals as adjustment parameters and processing the subsequent signals by the adjustment parameter processing module if the signal is a preset adjustment state entering signal; and never receiving the subsequent signals any more by the adjustment parameter processing module if the signal is a preset adjustment state exiting signal. The method for adjusting the parameters of the remote control model receiver provided by the invention is in no need of a trimmer potentiometer, input/output port wires and analog/digital conversion, and the model shell can realize parameter adjustment for the receiver without tapping.
