I'm a little stumped, I have a few more things to try but I figured I'd ask in the meantime.
QAV500, turnigy plush 30Amp, t-motor 4006, NAZA, spektrum dx8/AR7000 rx, all new (within 15 days). speed controllers not flashed, programmed default except high timing (per getFPV recommendations for that motor).
so, I do a CSC and motors 1,3,4 start spinning, 2 is stopped. throttle up to 40% or so and 2 will start spinning. If I hold the QAV off the table, some motors speed up, slow down, and sometimes even stop as if it correcting, but I am just not comfortable with why motor 2 acts differently than the others.
I've seen a post on setting dual rates to 105% - that didn't help. Another about reversing a channel (elevator I think) - that didn't help. And even a post that suggested 150% throw (I haven't tried that yet).
So anyhow, it seems a few have experienced this same thing, all with different solutions. I'm getting ready to put $2,000 up in the air and would really prefer to be a bit more confident. Anyone with specific experience?
