The S-1 Robotic Bird is a flying, radio-controlled (RC) ornithopter that you build yourself. Of course it flies by flapping wings. But the S-1 Robotic Bird goes a step further. It has an onboard computer that acts like the brain of a real bird, giving you complete control over the wing movements. That makes it one of the most advanced RC ornithopters available to hobbyists.

The S-1 Robotic Bird uses two powerful servos to move the wings. This sets you free from the restrictions of the old crank mechanism used in previous RC ornithopters. Wing movements are now used for steering, so there is no need for any separate mechanism for moving the tail. Another unique capability of the S-1 Robotic Bird is that we can vary the flapping angle of the wings. This allows a smooth transition between flapping and gliding flight.

The "brain" of the S-1 Robotic Bird is a tiny electronic device called the Axon-1b servo controller. Made exclusively for BirdKit, the servo controller weighs only 4.7 grams. It uses independent motion of the left and right wings for steering. It features a glide mode and variable flapping amplitude. The servo controller reads the throttle, aileron, and elevator commands from your radio receiver. Then it outputs a new signal to drive the servos in the RC bird. The latest version works with almost all RC receivers.

The S-1 Robotic Bird is available with or without the servo controller, in case you want to build your own controller and program the wing movements yourself.

The S-1 Robotic Bird is easy to build, but you should have some prior experience flying RC planes. The S-1 Robotic Bird requires two servos, micro-size RC receiver, and a lithium battery approx. 700 mAh, 7.4 volts. For the servos, we recommend Hitec HSB-9370TH digital brushless servos. There are also some lower cost, but less efficient alternatives such as Turnigy BLS25HV.
