Hi mate from Australia, was having similar issues. I needed to go into transmitter servo settings and reduce throttle sevo to -120%. Then individually calibrate throttle range for each esc. Then go back into transmitter servo settings and reset the servo back to 100%. Then connect to naza...
Hello I have been flying a f450 for about six years and am still using the original red motors 2212 920kv. I have done all sorts of flying with them and they work a treat, never missed a beat, even after crashing into a gum tree and it sat there for a week till I could afford to get it down, LOL!.
Bruce365, mate have been reading your advice and it has solved throttle issues I was having setting up my hexacopter you are the man.
now all I need to do is get it to fly longer,
Thanks again mate you are a legend.
Pete
