Okay, guys, I have two problems. I wanted to calibrate my ESCs through M.P. but I have T-Motor Air 40A ESCs and couldn’t find any info on what protocol they use 1Shot? DShot? So, I figured that maybe they are pre 2015, and are analog, so decided to use the old method of calibrating them by turning on the XTR, throttle up and power up the aircraft. The aircraft came alive but the ESCs were all beeping slowly - they did not respond to throttle movements. I repeated the process - no joy. So, I calibrated each one individually by plugging each one into receiver ch 3 and doing the throttle range thing - that seemed to work, so I left the ESC setting in M.P. to the default: 0. Now I’m wondering if I should have replaced the ESCs - could they be responsible for my motors not running smoothly in synch???
Anyway, I have another problem. I thought that I’d try to power up the aircraft using my 10000 mAH 6S lipo - it was charged to 21.8V which I thought was sufficient to do the motor test. But when I powered up the aircraft, M.P. complained “BATTERY ONE UNHEALTHY” I had previously gone to the Battery Monitor page and made the following settings:
Uploaded are three screen shots. The first is the Batter Monitor Page, the second is the Battery parameters on the Standard Parameters page and the third are the battery parameters on the Full Parameter Tree page. I changed some values to what is shown. Also, I noticed that my lipo voltage had dropped below 22V, so Iam charging it as I type this:
As i think for motor test also the FC must be in a armable stage but with battery voltage below 22V it is not armable as per your settings. So with 21.8V batttery voltage is to low.
I charged it to 22.8 v. but still got the warnings. And the ESCs beep slowly, indicating to me that either they are not getting signals from the receiver, or they are not calibrated (or both). Below is a pic showing how I connected the receiver, Pixhawk and ESC connections.
If it is a standard Lipo cell the nominal voltage is 3.7 V.
The maximum voltage (charge cutoff) is 4.2 V and the minimum voltage (discharge cutoff) is 3.0 V
Nah, that’s not right. And whatever charger you have should end with a full charge not 22.2V. But, this won’t prevent Motor Test from running. You are using Motor Test right, not the transmitter to test the motors?
I will hook it up shortly and let you know. But I have two questions - I was examining parameters and there is one I’m not sure about: RC_OPTIONS The documentation lists 10 possible values but mine is set to 32. None of the 10 values in the documentation seem to be what I want. I’m using an I-Bus receiver - should I just leave it as is?
