A flying_wing model is used. The wing-span is 120 cm; the weight to be flied is 700-1000 g. The model is heavy enough, mobile and stable so as to avoid severe dangling in the air flows, but it is sufficiently compact for conveyance.
Launching and landing on a small field. The motor with the static traction of 1200 g allows launching of the model from hand and taking off vertically upwards. A large glade is necessary for landing of the model for the reason of a high speed of the flight and of a sufficiently good air-dynamics. Seeking for landing of the model on a small field, I used braking with the help of the motor. The common speed controllers of the brushless motors do not allow switching of the reverse on during the flight. Thus, I installed the relay of the reverse, managed by the extra channel. The reverse must be switched on when the motor is switched off. The scheme of connection:
Braking with the help of the motor allows executing steep lowering and total dropping of the speed in several meters.
The photo-camera "Canon IXUS 5.0" is an amateurish camera; its dimensions are small and it is contained in the metal case. A recess is cut out in the center of the foam-rubber wing for installation of the photo-cameras; thus, the photo-camera does not almost stick out. The photo-camera is used in the constant photo or video shooting regime. The 2 Gb memory card is fully filled during in 5 minutes of flight. The necessary arrangements are as follows: a short exposure, the fixed focus, the shutter button remains clamped from the moment of launching of the model. Several mostly successful photos may be selected out of 1000 taken photos after landing. This photo-camera has an analogous video output; the signal, coming out of it, is transmitted to the earth in the course of flying, seeking for a more successful positioning of the model. 0,5 W, 1 GHz transmitter was used for transmitting of the video signal. The portable TV-set was used for reflection of the signal.Once the model crashed to the ground at a high speed, but the photo-camera remained undamaged.
Usually the servo is used for activation of the camera, but it is not an enough elegant decision. Some cameras are provided with special remote radio control panels; the controller RC-Shutter may be applied for other cameras.
