UAV- Determining Constant Velocity - Page 2 - Electronic Circuits Projects Diagrams Free

It's an RC. At the starting scale (a slowflyer) I don't think an airspeed sensor would even be able to measure anything- I think the total pressure is expected between 63millipascals to 2.25 millipascals which pressure sensors (that I know of) can't come close to measuring. But these are me using the speeds I'd like the plane to fly at- I think they actually fly a lot faster for the load I want to carry.

EDIT: ahh, that's why my pressure numbers are bogus. Even a plane flying at 100mph would produce pressures too low...r in the equation is the density of the fluid and not the radius of the tube.
