As a retired and frustrated engineer I have decided to build a homebrew quadcopter – not a racer -with a view, long term, to creating my own software for flight control and any other functions. The airframe is already built with four 2213 motors, and 1045 props, at 550mm diagonal distances being fed by four simonK 30k 2-3S ESCs. I have also have the new version Flysky FS-6S six channel digital Transmitter/controller and FS-iA6 Receiver on order.
Advice is needed on the choice of a suitable flight controller, compatible with the receiver and the ESCs – and which also meets these requirements - incorporates giro and inertial functions – is price sensitive – facilitates possible future inclusion of barometric and gps functions and also provides adequate information and backup to put the system into service. Any help would be appreciated please.
