The Espresso

From Quadshot Wiki
Jump to: navigation, search

The Espresso is a Cappuccino kit PLUS a Lisa/M v2.0 "brain" and two xBee modules for wireless data transmission between the aircraft and a computer on the ground. We also include an extra pair of propellers, for a total of six. The Cappuccino is unassembled and great if you have your own project in mind, or want spare Quadshot parts. The Espresso is unassembled and great for R/C and software enthusiasts interested in both flying and hacking with the aircraft.

Airframe

We designed the Quadshot’s airframe to be lightweight, yet durable. It features 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, are removable for easy storage and transportation, 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.


Additional Necessary Components

To fly, the Espresso requires a battery and a radio system. We recommend using a Spektrum® DSM2-compatible radio transmitter and two Spektrum® DSM2-compatible "satellite" receivers such as the SPM9545. Note that a main receiver (e.g., with servo outputs) is not necessary, as the remote receivers plug directly into Lisa, which decodes their output.

Other radio systems may be compatible but may require modification, software configuration, and/or additional components to function.
