Not my blog (sorry Luis!) but I didn’t know if I was the first to fly a Pixhack V5 in a heli or Luis beat me to it.
Stuck to the side of the frame with Velcro. I really like the peripheral rail on the end of the carrier. Makes for neater wire routing. Somebody figured out that the GPS cables are usually too short and a few cm extra cable means not having to hack a cable extension. And the cable is round so it’s easier to route.
I didn’t install the buzzer/button as I don’t care for music tones emanating from my helicopters. Neither did I use the Power Module as this unit will be going in a piston helicopter next. We only monitor battery voltage with the RC telemetry in those, as the generator keeps the battery charged. So I made up a power cable to run the board on a 2S LiPo with a 5V regulator. It will have redundant power supplies in the piston machine, but for this test we just hooked up one.
The vibes are mostly below 5, but a few spikes up to 10 in the rolls. IMU aliasing is, like, not there. Non-existent. This thing looks to be every bit as good as the Pixhack v3 for the internal IMU damping design. For some reason, ChibiOS does not appear to be putting a date stamp on the BIN logs. That is normal when there is no GPS, but it had 20 satellites on this test and still no date stamp on the log except for Dec 31, 1979. Unix Epoch is 1969, so that must be because the SD card has a FAT file system.
