kasra.mirshamsi replied to mohammad sajadian's discussion Fly-By-Wire A is not Working
"Ok I just change the throttle parameters, things got much better, now when I switch to autopilot board no matter any mode the throttle cuts off only about 15%.
Another thing which I did and it might was the reason was I change the regulator voltage…"

kasra.mirshamsi replied to Lance Lefebure's discussion IMU Gyro Stability
"Hello, this thread is from 2010 hopefully somebody be out there !!
I recently face a strange behavior with my IMU (gyro and acce). It is like a noisy sensor response.
On the flight data tab in the mission planner I noticed that when I rotate my…"

"Hi people , I have a Rx/Tx spectrum dx6i, and my probem is whenever I switch to either FBWA, FBWB or stabilization mode or any other flying mode the throttle fully get closed. And when I switch it back to manual with (gear switch) the throttle goes…"

"Hi, I check the output of the noisy gyro and acce
I just add these line to the voild loop to see the raw values in the serial monitor
u can see noise within the imu values, Whenever I tilt the board and leave it on its level position the Gx  and Gy…"

Hi, on the flight data tab in the mission planner when I tilt my board and then rest the board on its level position, the bank angle as well as the pitch angle lose their level positin I mean they rest on a deflected position. This happnes most of…

kasra.mirshamsi commented on Roy Brewer's blog post Accelerometer question for IMU Experts
"Hi guys, I came late to this debate its been 3 years. I read all your comments about what acce sensor measures and understand that it measures specific torques\accelerations, every force except the gravity.
Here is m y situation, I have a 3 axis…"

Hi folks, does anyone has any explanation why when the AMP/IMU  board is static still the values of gx gy gz changes, should't they remain at zero. The intresting thing is that on CLI test mode I get zero values for gx gy ang gz while on the flight…

"Hi, I need a help regarding to my mag sensor. I connected the Mag sensor to IMU sheild based on method 2 given on the website. I am pretty sure about the wiring and I have uploaded the arduplane code v 2.3 through adruino IDE.
 I've then gone to CLI…"

"Hi there, Why the iphone 4 GPS module (iGPS-360) locks even indoor and much faster compare to this Mediateck 3329 module which strugggles a lot to lock indoor If  it is left 1 hour next to the window.!!! Any idea.  "
