Title:
RADIO FREQUENCY CONTROLLED TETHERED AIRCRAFT
Document Type and Number:
WIPO Patent Application WO2004096639
Kind Code:
A3
Abstract:
The present invention (10) discloses a model aircraft (14) for preventing the fouling of control lines for tethered aircraft controlled by means of radio frequency transmission (12). The present invention (10) has a coupling (22) for model aircraft attached by a semi rigid conduit (20) to a base control unit (18). The rigid conduit (20) is a composite material tube providing anti-sway control. The tube (20) houses a lubricant and drive cable (40) connected to a coupling (22) connecting the aircraft (14) to the base control unit (18) whereby various aircraft may be substituted. At the other distal end the semi-rigid member is removably secured to a drive module housing the drive motor (36) that forms part of the base control unit (18). The base module (18) houses a power supply (52), receiver (48), servo motor (50) and speed control (46). A hand held remote control (12) unit is used to transmit control signals for the aircraft elevator control and prop speed.
