For Stabalisation, do i need both a Gyro and an Accelerometer? A 3 axis accelrometer like MMA7361, would it work?? Why do i essentially need a Gyro sensor??
And what if i use two accelerometers? one for Horizontal and one for Vertical? would that do??
I have a Coaxial Helicopter, essentially a cheap one, with 2 Brushed motors on it for the blades and another brushed motor for the Rotor Blade.
i would tie a thread on the Main shaft and see how the helicopter is positioned. That would give me a fair idea of where the CG lies i guess.
