I took my Navio 2 powered drone out for a maiden flight on the weekend. I had done all the pre-flight setups and checked my motors were spinning as they should and the props are on where they should be.
On my takeoffs I would experience flips / roll overs. There is a video here that shows: https://www.youtube.com/watch?v=mMokRyuHsjo
I recalibrated my ESCs as I have been noticing my #4 motor is sometimes sluggish off the mark. No amount of ESC calibration seemed to change the fact that it is a split second off the others.
If I throttle up slowly and evenly the #4 seems to start at the same time. But, if I throttle up and down fast (twitchy throttle up, then cut to zero as quick as I can)- motors 1, 2 and 3 all start up and shut off fine. But my #4 never gets going. It seems slow so to respond to the RC inputs that it misses the starter’s gun entirely.
I suspect this has something to do with my roll overs and flips.
Can someone give me some advice about whether I can solve this?
My next trouble shooting step will be to swap motors to see if its related to motors or ESCs. I can only think my options are replacements. Would love to know if there is other options
Thanks in advance
