Well, this is sweet. It’s a remote-controlled helicopter with a Canon 7D strapped on board, allowing creator Eric Austin to capture some downright badass pics and video. I want one, badly. [DIY Photography via Make]

Tuesday, April 27, 2010 at 11:00 AM@farcedude: you’re way off the mark explaining the angle in all the shots. The direct cause for angle of the shots is the torque of the motor, every single electric based heli suffers from this effect.
everything from a 250 right up to a 700. as you go up in size the effect becomes decreasingly noticeable but its still there. im not 100% sure about nitro and turbine rc helicopters but i will assume you still have the same motor torque effect.

It is the tendency for the helicopter to rotate about its vertical center of gravity (CofG). The amount of roll is dependant upon the vertical offset of the tail rotor from the vertical CofG, and the magnitude of the tail rotor thrust applied. The direction of the roll is dependant upon whether or the not the tail rotor lies above or below the vertical CofG, above will result in a roll towards the advancing side, and below will result in a roll towards the retreating side.

Tuesday, April 27, 2010 at 3:49 PMTo combat this roll, you could use IMU (with which you can counter movements in axis thanks to the gyro’s to stabilise the camera with some servo’s) but it would mean having to control the camera independent of the heli.

Need CASSA or whatever licence in Aus though.
