About Me:
I am a software engineer BA in Physics. See my former year 2000's hardware & software work towards an autopilot at the link below: www.inertial-solutions.us
Please tell us a bit about your UAV interest
I want to fly my big old airplane (9' wingspan, 18 lbs) on autopilot from take off to landing.

"Planes need ESC RPM & Power feedback too. Plane autopilots need to know motor RPM and Power when flying the plane (takeoff-landing-cruise) and also when analyzing the air frame performance (Lift to drag ratio). The airplane cannot be properly…"

Hi Emery, The model airplane you asked about is made of balsa with some Plywood hard points and epoxy-fiberglass skin strength added in the wing-motor-landing gear areas. The fuselage construction is simple on a…"

"I too had "Bad Compass Health" until I moved the telemetry wires away from running along the top of my Pixhawk. Any wire carrying electric current produces a magnetic field circling it. The more electric current the more intense is the magnetic…"
"RPM feedback is available as pulses on an auxiliary line (white wire) from the Castle Creations Phoenix-Edge series of Electronic Speed Controllers (ESC) at 50, 75, 100, 130, or 200 amps. The ESC toggles the AUX LINE at every electrical…"
Learning and Using Airplane Lift/Drag by FRANCIS NELSON HENDERSON June 18, 2014 Plane autopilots are installed in new airplanes without knowing best glide speed, best endurance speed, optimum cruise speed, top cruise speed, or even the stall…
"Thanks for your reply, Iskess. Yes, my hope in writing "Learning and Using Stall Speed" is that the developers will see the paper, thereby possibly helping to simplify and improve the plane autopilot."
Stall Speed for ArduPlane: by FRANCIS NELSON HENDERSON June, 2014 Stall speed (Vs) is unknown at every new Ardupilot installation. Yet, the autopilot needs to know Vs in order to determine takeoff speed, minimum banked turn speeds, accelerated…
"Since the landing approach must be made as slowly as possible, but yet with a safe margin of speed, the stall speed plays a big role in determining landing performance. The FAA mandates large airplanes must use an approach speed of not less than 30…"
"Accelerometer calibration is independent of the GPS, however the compass learns the local magnetic "deviation" (needed for compass calibration) from information contained in the GPS satellite downlink. The magnetic deviation gets stored once it is…"
It's amazing the contribution Andrew Tridgell is making. I love how the new version installations are automated on my APM 2.5. I'm waiting for the next major upgrade (3 ?) before flying my big plane on the new Pixhawk. The 32-bit STM32F427 Pixhawk…
