Abstract: Systems and methods for stabilizing the steering and throttle of a radio-controlled (RC) vehicle are described herein. More specifically, sensors and circuitry are configured to control the wheel speed and wheel direction of a RC vehicle based on rotational information. In operation, one or more sensors may be configured to receive angular rotational information associated with a rotation of the RC vehicle. The rotational information may define a rotation of the RC vehicle around one or more axes of the RC vehicle. The circuitry may be configured to receive the angular rotation information associated with the rotation of the RC vehicle from the one or more sensors, and control a wheel speed and/or a wheel direction of at least one wheel of the RC vehicle based at least in part on (i) command data received from a controller associated with the RC vehicle and (ii) the received angular rotation information.

Abstract: A three dimensional digital spectrum modulation spread spectrum technique (DSM-X) that improves channel diversity by providing multiple bands within the available portion of the frequency spectrum increasing the number of available channels. The system also improves the channel immunity through the use of at least three dimensions of pseudo-random data encoding, which adds two levels of pseudo-random frequency allocation to the pseudo-random data encoding used in prior DSM systems. The three dimensions of pseudo-random allocation may include pseudo-random data encoding, pseudo-random frequency pattern allocation among a plurality of bands defined within the assigned frequency spectrum, and pseudo-random frequency sequencing among a plurality of channels defined within each band. Additional levels of pseudo-random encoding may be implemented in direct sequence coding for header data, repeat packet timing, and packet iteration timing.

Abstract: The present disclosure describes an indirect motor drive train for RC vehicles. Example embodiments include RC vehicles such as helicopters (and more specifically quadcopters) with a housing and housing arms that extend radially from the housing. Protected within each housing arm is a motor and indirect drive train. In operation, the drive train may include a first gear and a second gear with corresponding teeth that mesh together to translate motion from the motor axis to a propeller axis.

Abstract: A radio-controlled (RC) aircraft has a wing lock and disconnect mechanism. The RC aircraft has a structural member and a wing that disconnects from a fuselage. The RC aircraft has a lock mechanism, a wing structural member recess, a fuselage structural member recess, a lock recess, and an aperture. The lock mechanism couples to the wing and is adapted to fit within the lock recess of the fuselage. The wing structural member receives the structural member. The fuselage structural members recess corresponds to the wing structural member recess. The lock recess receives the lock mechanism. The wing disconnects from the fuselage by unlocking the lock mechanism. The structural member fits within the wing structural member recess and the fuselage structural member recess.

Abstract: Example implementations may relate to an RC vehicle with a receiver and an inertial measurement unit. In particular, the RC vehicle may include vehicle controller circuitry that works together with the inertial measurement unit to instruct the receiver to enter a bind mode when the RC vehicle is rotated, oriented, or positioned in a certain way. In an example embodiment, the RC vehicle may instruct the receiver to enter a bind mode when the RC vehicle is first powered on and is rotated 180 degrees in a certain direction, such as from upright to upside-down.

Abstract: A wireless transmitter includes a pair of control sticks, circuitry coupled to control sticks, and an antenna coupled to the circuitry. The circuitry is configured to process signals produced by the control sticks to provide control inputs for the speed, direction, and other flight characteristics of the model aircraft being controlled by the transmitter. The transmitter is configured for multiple operational modes in which the pair of control sticks engage or disengage functionality, such as return-to-center functionality, vertical or horizontal position limiting functionality, or position select functionality.

Abstract: A remote control boat that includes a self-righting apparatus adapted to right the boat after it has capsized. In some embodiments, a weighted coupler is attached to the motor output shaft and the drive shaft to prevent the drive shaft from moving for a period of time after the motor is turned on. In some embodiments, one or more components may be attached to the weighted coupler by a set screw configuration. In some embodiments, one or more components may be attached to the weighted coupler by a collet-type configuration.
