Sorry for derailment - this is waay off topic for the airspeed sensor.

More specifically, "yaw" body rate maps to the left/right accel axis, and "pitch" body rate maps to the up/down accel axis. You don't need to know attitude of the banking turn because we already know that in a 6…

@GaryMortimer - shhhhh. NDAs are in effect!

Centripetal force, being a "false" force, depends on speed relative to the medium the vehicle is moving through and "pushing against" to generate the forces, with assumption that the vehicle is more or less tracking in that…

... and at these more extreme speeds, you could just ignore "airspeed" because any typical wind is now a small fraction of the airspeed, and just use GPS ground speed divided by Cosine of pitch to get body-speed. Common civilian…

The airspeed equation I use has a 7/2 power in it, and thus ram pressure builds rapidly with airspeed. So 7Kpa is not at all unreasonable for measuring airspeed in really fast RC planes or UAVs, for example powered by a…

The Diff P sensor pictured on top right of the Atto board (Freescale MP3V5004G) is describe as "Gauge" type. One port is the nipple as shown, the 2nd port is a vent hole on backside of the package. The 8 leads are structured so that…

@Bgatti "This is the AttoPilot choice - at 3.92 kPA it has ~10 times less range."
Yes - the "AttoPilot" choice is a choice that perfectly matches dynamic range of sensor with dynamic range of what is being sensed. …

- Actually, I am just starting RC flying in general as a hobby. I bought a Slow Stick as my first plane and I need to learn to fly it first. Once I get the hang of that, I will start to build my UAV. I've already built autonomous vehicles before, but that was on the ground. I've even built an underwater ROV before too.

- Dean,
If you are in the Queen Creek area again sometime, would you mind if I tagged along?

Scott James said… - Hi Dean,
Put me on the list of people that want to buy an AttoPilot!
Can you please let me know when it is ready for release.
Thanks! It looks great!
