A prompt drop device for a remote control model airplane comprises an airplane body (1) and a horizontal tail (3). A support (2) disposed on the airplane body (1) is used for supporting the front end of the horizontal tail (3). The front end (8) of the horizontal tail (3) is rotated under the binding of the support (2). A driving device is connected with the horizontal tail (3) and is used for lifting the rear end of the horizontal tail (3). A remote control model airplane comprising the prompt drop device is provided with the movable horizontal tail (3) and controls the angle of the horizontal tail (3) during landing, so that vertical descending is realized, and damage during landing is avoided.

The present invention discloses a wheel of a remote-controlled toy vehicle, comprising: a wheel body; and a wheel drive means; wherein the wheel body comprises an inner cavity, a rolling component, and a coupling component; wherein the rolling component is rotatably mounted on the coupling component and in transmission connection with a power output end of the wheel drive means; and wherein the wheel drive means is mounted on the coupling component and positioned within the inner cavity. The present remote-controlled toy vehicle wheel can be independently controlled, enabling various movement modes of the remote-controlled toy vehicle without occupying space within the vehicle body.

A quick-release body attachment system for model vehicles, wherein one or more grooved pegs are inserted into one or more alignment holes of a cantilever straight spring assembly, as the vehicle body is attached to the vehicle chassis. Once the grooved pegs are fully inserted, cantilever straight springs spring into groove of the peg, securing the vehicle body to the vehicle chassis. Applying force to the release handle mounted to the cantilever straight spring, release the spring from the groove of the peg, allowing the vehicle body to detach from the vehicle chassis.
