About Me:
Novice RC constructor - Retired aerospace avionics engineer - embedded computers and digital flight control. Intern transistorizing the B-58 Nav Bomb computer - then the Gemini IBM onboard computer. Project design/development engineer for the HARPOON/SLAM digital strapdown guidance/control subsystem.(hats off to Permerlani & Mahony). Design and mechanization of the F/A-18 HORNET quad redundant digital FCS. and many other fun things.
Please tell us a bit about your UAV interest
Aerial photography. My nephew is a forensic fire scene investigator and consultant. Want to end his chronic gripe that large scale fire scenes are disturbed - sometimes demolition has begun by the time the investigators are turned loose. Learning to construct/fly/flight test Magpie AP aircraft. Much underrated A/C for slow flight - low altitude - high res photos. Understand the theory - amazed by the tiny hardware (Harpoon S/D = 25lbs.) Blank mind about the I/F conventions and alphabet soup) Looking for young bright mentors in exchange for math and tribal lore questions.

On new APM1 system, the instructions went smooth up to setup -radio check. No variable bars. on exit all 6CH read 0=min 3000= max. Latest AMP, new hardware, arduplane software. functional Tx. Servos follow the stick OK!. Modes switch OK, params…
"OK jokes on me - I printed out the new easystar.param file and there at the top was the title- "4:22:48 PM Easy Star Post Crash". Deduction - this IS the new easystar file and it IS loaded into the onboard A/P OFP (firmware to you) and it IS safe…"
In using the Mission Planner (Ver 10) to upload the A/C specific configuration (easystar.param).via the AMP a dialogue window opens with the title "SAVED NOTE" with the message "4:22:48 PM Easy Star Post Crash"The OFP (firmware) loads ok with the…
"Hi Itzik Somehow ended up with a freind request from you. I noticed your intent to acquire X-Plane. Be advised from my own experience that this Ver 10 requires great processing power - at least - a 2-core 3 gigaherz computer, gobs of RAM, a game…"
The form fitting cockpit electronics rack kit includes 8 Nd-60 magnets to secure the rack to the Easystar foam cockpit cavity. Slick. About to install the magnetometer option to improve heading information.This puts the magnetometer sensor 3cm…
HiWhile waiting for an assembled A/P Mega to arrive, I downloaded and extracted the APM software - opened it and searched on but could not find the directed ArdupilotMegaPlanner.exe file. I did find a file named ArdupilotMegaPlanner.exe.config but…

I would be interested in hearing your ideas. Here are are a couple of ideas I have seen used in the past on production avionics to expand the limited number of discretes on old equipment just with software changes.First - have you read on…"

"The R Pro is a sailplane so you should have no problem finding the right cg by hand launching. Still, other thoughtful comments express concerns about the attitude at crash. Let's review these items of the crash trajectory as you prepare for flight.…"
"Not experienced enough to take you under my wing but will pass along what I learned fom the best pilot in the St Louis RC Flying Assoc.
Chris is right - cg is critical and I have many crashes to prove it. JH took me in hand and gave me a feel for…"

"Ian - Some added information that may be of help to you in your camera pointing development effort. As I wrote, I had in mind the camera orientation defined in the attached sketch. For a forward looker, the azimuth gimbal angle, alpha, would have…"
"There has been a lot of air over the wing since we last corresponded. Good to hear from you. Have been studying the completed Ardupilot/IMU, and have a much better grounding in the current technology. Let me say I am impressed at the sophistication…"
The title says it all. Which of the two shield mounted air pressure sensor ports is to be tubed to the static pressure tube? The A/C testbed is a very slow flying foamy - 12x8 prop geared down to 6:1. Trial and error results are indeterminate…

Topic - Project to slave the camera gimbals to the IMU Inertial reference frame. This is the way it is done in Military aircraft. No extra hardware required.

"I am flattered, Kyle. Newton remarked that if he had accomplished great things it was because he stood on the shoulders of those that had gone before him. You have a clear perspective - Newton did well - you will too.
