Gyro-Stabilized PTZ Gimbal for UAVs


I am an ex-USAF Avionics Sensors guy, and I have always wanted a gyro stabilized laser targeting system. Now that I am all grown up, I'll settle for a gyro stabilized camera.


A little looking, and I found some nice UAV equipment.It's a little out of my price range at $10,000 for the day system and $20,000 for the FLIR system.


Now I know this is mechanically and electrically easy, but for me this could become time-consuming. Can we make a cost-effective system for our UAVs?


Some examples:

Rule of Thumb for Power to Lift

1 horsepower = 7 pounds

I've come across this magic number using different sized rotors, props, and engines in large RC helicopters and planes, and also researching horsepower to lift divided by time in several ultralight and light sport aircraft and rotorcraft, and this is a good rule of thumb when developing something that needs to do more than hover or drift in the wind.

Guidelines for precise calculation of lift or thrust

Comparison information using UAV specialist developer information

Be sure to click on the different links for engine type (4 stroke, wankel, turbine, etc.) In fact, Barnard Microsystems is an excellent reference for those looking to DIY a larger drone, and is highly informative reading material in all aspects of UAVs.
