Aug 31, 2011 2 Comments

Initial flight testing of the Frenzy 90 was delayed because of my attending IRCHA, obtaining some support equipment and bad weather here in Florida.

Servo City Servo Stretcher

Aug 27, 2011 No Comments

One of the big issues with onboard camera setups is getting the pan/tilt system to rotate further than 90 degrees.  Most analog servos are designed to rotate 45 degrees in each direction, but with the servo stretcher you can boost the signal to the servo to gain a rotation of 90 degrees in each direction.
