The idea was to get away from the usual buggy/rider mounted cameras and really try to get outside the buggy for a new perspective. I was encouraged early on by footage from my first field trial to pursue this idea.
Initially I expected to move the ROTOcam boom into position myself while riding but I soon realized that I could influence the boom's motion without ever touching it.
To my surprise the boom would move with predictable and repeatable motion with simple inputs to kite and buggy. For example, downlooping the kite would spin the boom 360 and the boom would then return to it's original parked position!
The result I think is quite strange. Its motion is anything but random and its almost like the boom has a life of it own or like having someone up there moving the boom around for you.
Adding or subtracting small weights would alter its natural resting position and so I could park the boom anywhere around the buggy I pleased.
Using the Dominator buggy made attaching bits and pieces to it very easy. A typical buggy axle may present an extra challenge but with additional supports could be accomplished fairly easily I'd should think.
The basic build ingredients I used for the ROTOcam are :
1 metre of 10mm threaded rod,
A landboard wheel with bearing
A telescopic fishing rod
Mr Fusion power pack and NOS optional.
Screw one end of the 'thread rod' into the Flexifoil headstock and the other into the landboard wheel. Clamp a fishing pole to the wheel and clamp the forks to the buggy. Attach a camera and go.
Experiment and have fun!"
