arming problem - please help

[Robert Nascimben]

I calibrated my hobbywing 40A esc's and when I arm my naza, the motor do not spin at all until I hit approximately 40-50%. Before calibrating the esc's it worked fine meaning that when I arm naza, the motors start to spin. I did move the idle to high but same problem. Just worried that in flight if I drop to 50% or lower, the octocopter will fall out of the sky . Also in manual, the motors do not spin until 40-50%. Any thoughts on this? Thanks

I had the same problem with a MR that I had bought second hand. It was built professionally by walkera and when contacted they claimed it was the nature of the setup. I was worried about it dropping out of the sky as well. I flew the MR and it was fine, I just made sure I never went below 50% throttle ( I could still hover and land). I have since switched from intelligent cutoff to immediate cutoff on all my Naza MR's and not selected the recommended setting for idle but rather one lower. When flying my MR's I never go lower than the first line below 50% on the throttle and have never had a problem, but I did sell that MR so I don't have a lot of experience flying it that way.

Thanks John. I have a feeling it has something to do with the Transmitter's throttle calibration. I have two drones and the other one works perfectly and I noticed last night that the other Taranis X9D TX has the throttle going from -100 to 100 where as my other Taranis X9E goes from 0 - 100. I am going to re-calibrate the TX to make sure it goes from -100 to 100. I also found that within the Naza Assistant the motor tests do not work which seem again to suggest the low throttle range is set incorrectly. I will do the calibration, re-calibrate the ESC's and hopefully the motors will spin as soon as you arm the TX.

John, I just re-calibrated the TX and the range now goes from -100 to 100. I re-calibrated the ESC's and now it works properly. You can arm Naza and boom the motors start immediately. Whew!
