Weeks+Shipping: Weeks (B2B order). Ordered from the company's B2B store in the Czech Republic. Consumer orders are not fulfilled. Flapper store ↗
Remote control: A Crazyradio USB dongle lets the Crazyflie Python library (cflib) and cfclient send setpoints and read telemetry from a laptop.
Overview
The commercial, enlarged version of TU Delft's DelFly Nimble and, per its makers, the first hover-capable tailless flapping-wing drone offered for sale. Because it runs a Crazyflie Bolt, it plugs straight into the Crazyflie ecosystem, so Python scripting, swarms and Lighthouse/mocap positioning all work as on a Crazyflie quadrotor. Aimed at research labs, drone shows and museums rather than hobbyists.
The only practical way to buy a programmable, hovering flapping-wing robot.
