Hey folks,
I'm a researcher that's been working with the M600 Pro since the Fall of 2018. I'm trying to get our UAV operational after a crash I had in December, and hopefully learn the ins and outs of proper maintenance/assemlby along the way. Our M600 is rebuilt, but after some quick tests this morning I am nervous about the UAV crashing, and breaking more propellers/antennas, etc. Currently I'm working with the A3 Pro (2/3 A3 antennas installed) and the RTK-GPS.
My current question is:
1) Once propellers are tightened, how much resistance should there be? I've replace several sets of propellers and at this point there is some degree in variation between each arm and their tightness. Can propellers that aren't screwed in tight enough cause flight instability? I powered on the motors (but didn't take off) and let them run for a few minutes trying to observe any variable differences in propeller RPM's, but couldn't see anything. However, once I powered down the motors some the blades aren't straight (left picture) while others are (right picture). The ones that aren't straight also seem to be the most loose, and I can't seem to tighten them up.
I would greatly appreciate any feedback/pointers!
