The Espresso (kit)
For R/C and software enthusiasts interested in hacking with the aircraft. It includes the airframe, four motors/propellers/motor controllers, two servos, one pre-flashed Lisa/M v2 module with pre-mounted Aspirin v2 10DoM IMU, two XBee wireless modules (for bidirectional communication to a groundstation computer), and all necessary wires, connectors, and fasteners.
To complete the kit, you will need: a Spektrum-DSM2-compatible 2.4GHz R/C transmitter; two Spektrum-DSM2-compatible satellite receivers; at least one 2200 mAh 3-cell lithium-polymer flight battery; and an appropriate lithium-polymer battery charger. The Espresso is a kit and requires assembly; the assembly manual, flight manual, and a list of compatible hardware are available online in our wiki.
BRAIN - The Quadshot differs from a typical remote-controlled airplane or helicopter in a big way: it has a brain! The Quadshot Espresso's brain is called Lisa/M.
Like the flight computer on an advanced aircraft or unmanned aerial vehicle (UAV), Lisa/M is equipped with a sensor suite called an Inertial Measurement Unit (IMU). The IMU contains 3-axis solid-state accelerometers and gyroscopes to keep Lisa/M up-to-date on which way she is pointing and how fast she is rotating.
Lisa combines all of this information with your commands and then decides what to do hundreds of times per second. The advantage of being so brainy? You can tell the Quadshot to hover like a helicopter, fly slowly and steadily like a trainer airplane, or give you full control for aerobatics - all at the flip of a switch.
Lisa may be small, but she’s powerful - and hackable! Lisa’s hardware is open (OSHW), and she runs flight software based on the Open-Source Paparazzi project - which means you have the power to make changes, and also benefit from improvements made by others in the community.
AIRFRAME - We designed the Quadshot’s airframe to be lightweight, yet durable. It consists of a one-meter (39 inch) wing, four pylons with motors and propellers, an enclosure for the electronics, and a standard threaded mount suitable for a small camera. The wing is made out of EPO foam, with a carbon-fiber spar for strength. The pylons are plastic-reinforced foam, and act as landing gear, motor mounts, and tailfins. They are set farther apart on the bottom of the wing to give your camera a clear view.
Ships in a box approximately 37" x 14" x 4" (94cm x 36cm x 10cm). Shipping weight is approximately 3 lb (1.4kg).
