Thanks for the posts. Here is what I did last night. I had some good sucess but now I have a new concern.
I decreased the throttle trim from the 25% (1/2 down from the default 50% setting) to 0% (full down). This got the PWM value down to 1017 (see picture ending in _212836.jpg). I tried to calibrate the ESCs after that but the Motors/ESCs would still beep and twitch.
Then I went into the “Travel Adjust” menu on my DX-7 Transmitter and while watching the throttle value on the “Radio Calibration” screen of the Mission Planner software, I adjusted the “Low Throttle” travel adjust over 100% until the PWM went down to 980 (see picture ending in _213725.jpg). The “Travel Adjust” setting that yielded the 980 PWM value was 108% (see picture ending in _213758.jpg). After doing this I tried to calibrate the ESCs again but they would still beep and twitch.
Then I re-calibrated the ESCs again. It seemed to calibrate correctly and after the “confirmation” beep I raised the throttle and all of the motors spun up at the same speed. Then I disconnected the Flight Battery and reconnected it again. This time it sounded the initiation series of beeps (three beeps to indicate a 3S battery pack) then no beeping or twitching…. Hooray!
At this point I had the props off. With the motors seeming to run okay, I would put in a Yaw input and I could hear the motors change speed but when I gave it a series of yaw and/or pitch or roll inputs, all of the sudden all six motors went to full speed and I could not get the speed to come down until I disconnected the Flight Battery pack. This is not good!! What do you think is causing this to happen? Now that I have the ESCs calibrated should I change the setting of the “Travel Adjust” back to 100%, and/or should I adjust the “throttle trim” setting back to 50% (default)? If I change the setting on either of these settings should I do the “Radio Calibration” using the Mission Planner software again?
Please let me know what you think because I do not want to try to fly my Hexacopter if it is going to arbitrarily go to full throttle on all six motors!
Thanks,
Dale
P.S. When I was running the motors (without props) I noticed a lot of vibration on several motors. Once I get the “Motors going to full throttle issue” fixed I want to try to balance the motors. Like I was asking before, is there a Command Line Interface (CLI) that I can use to select only one motor at a time so that I can balance the motors one at a time?
