Since I am a physics prof and teach angular momentum conservation, I have to wonder how
much the copter will rotate in the opposite direction to the camera? Unless it is gyro-
stabilized, you might make a servo command for a 90 degree turn of the camera and have
the copter rotate 30 degrees in the opposite direction, resulting in an overall rotation of the
camera of 60 degrees relative to the ground.

Anyone doing this sort of think noticed this and had to account for it?
• most remote helicopter have some rather sophisticated gyro sensors built into them do they not? do they cancel out this sort of stuff? or just help normalise

• sure. nobody would dare fly a heli without gyro these days. preferably with a function activated called heading lock. most likely you will find a futaba gy401

sure. nobody would dare fly a heli without gyro these days.
preferably with a function activated called heading lock.

most likely you will find a futaba gy401 in 80% of all helicopters.
