Hello Michael, We have a problem with Teensy VTOL flight controller Arming ESCs - its a Nicholas Rehm project - link: https://www.youtube.com/watch?v=tlD0C5CrWcA but details of problem you can find in latest post here: https://www.rcgroups.com/forums/showthread.php?3580135-Profile-F-35-Tricopter/page20#post49071687 I wonder If you will find some time to look at the code and give us some solutions or tips?? Thanks Mike_58

I am using your post on "Roll and Pitch Angles from Accelerometer Sensor". The equation for pitch asin(Ax / G) does NOT work. However, asin(Ax / sqrt(AxAx + AyAy + Az*Az)) DOES work. In your write-up, it says G = 9.81 m/sec^2. Is this correct?? I'd appreciate your comments on this point. Thank you. AA

@AlejandroAllievi I think you might have a units mismatch in the numerator and denominator. For example, if your measurements are in g, Ax [g] / 9.81 [m/sec^2] won't work since the numerator and denominator have different units.

Thanks Michael, did not realize accelerations were in G's. Thanks again!!

Michael, are you open for some consulting work? We have an accelerometer used in a healthcare application and would like to get some help in calibrations, characterizations and ultimately writing some algos.

Hey there, Iv been wanting to start a similar project for the longest time using the umx flight controllers. What would be the cheapest and easiest way to start pulling data from the serial port? The umx flight controllers usually have extra connectors and I'm hoping to find a way to utilize them.
