Launch of smoke, comets, fountains and rockets by R/C models
The device "FireStarter" is developed for remote control of electric igniters. Up to six electric igniters can be connected to the device. For connecting the device, one of free channels of a standard receiver of the on-board R/C system shall be used. Igniters can be activated both by a choice and successively. The device issues a high level reliability and safety required on working with pyrotechnics.

The night lighting for R/C helicopter
"HeliStrobe" device is installed in R/C model of helicopter and controls operation of lighting elements on the sides of the model. Lighting elements are bright LEDs directed towards the rotor and the body of the model. The sequence of flashes controlled by the microcontroller provides an image of an immovable figure formed by the rotor. The shape of the figure is chosen from 15 various versions. The image of the model brightly lighted in the both sides in night is the same as in daytime. A change of the colour of lighting causes a change of the colour of the model.

It provides automatic response to approaching the ground for flying R/C models
The "DistanceSensor" is usable for preventing a wreck or "hard landing" as well as for flying on the fixed altitude over the ground. If the distance between pilot and model is equal to tens metres and more, a visual assessment of the altitude of flying becomes imprecise; it is complicated to assess the flying altitude precisely using the image of the on-board video camera as well. The device allows reducing the risk of flying on a low altitude.

The rhythm of the sounding music is reflected in the movements of the model
The modulus "Dancing Model" combines the flight of the model with the rhythm of the music. The microphone receives the sonic signal and transforms it into the infrasonic oscillations, which get added to the control signal. The modulus is connected to one of the control channels inside the control panel. The amplitude of the added movements can be regulated in the course of piloting. The method of controlling the model remains constant.

Automated pointing of the video-camera to the object, selected for shooting
The device "DirectionFinder" allows the camera to follow the necessary object to be shot automatically. The infra-red radiation sensor must be fixed on the active camera platform. A special infra-red radiator must be installed in the place, which must be reflected on the still. If the source of radiation is detected, the camera holds this dot in the center of the view. The radiator can be fixed on the movable object, for example, on the automobile.

Manual and automatic switching of control between two on-board receivers
"RX Multiplexer" ensures reliable control of a model in two communication channels. It is usable in long-distance flights or in case of control from two different points.

The three-positional double switch, which is controlled via one control channel
The "RC Shutter" is used for controlling the photo/video-camera or the board lights. Three regimes of operation are possible, i.e. consecutive switching on, separate switches and two triggers. The regime of consecutive switching on is assigned for controlling the functions of the photo-camera "focusing" and "shutter". The regime of separate switches is assigned for the functions "zoom in" and "zoom out" or for the "photo/video" regime switching. The regime of triggers suits for controlling the board lights.

Independent control for servomechanism with a delay of activation
"Servo Timer" device is usable for activation of the mode of forced landing in freely flying aircraft models.

Analog balancer for lithium batteries (Li-Po, Li-ion, Li-Fe)
It is inexpensive and precise device for equalizing the voltage between sections of a lithium battery. Versions for balancing two-section and three-section batteries are available. The battery cells with a higher voltage will be discharged in an automatic way until equalization of the voltage is achieved.
