I did a reversed inflation a few days ago - all was god - turned around but when I depressed the potentiometer,… nothing happened and the wing fell on my face😆 I still could hear the beeps and the 4 motors in synch.
The throttle screen was blank. Bummer! Drove back home hoping it was a disconnected wire I could see inside the throttle. I opened it and yes, I saw the ground wire disconnected from the board. Soldered it back on. Closed the throttle - turned the main switch ON - heard the beeps and the four brushless communicating. Then the moment of truth… two taps on the red top switch and bingo! I heard the chirping sound of the motors and good to go. All was well, except that the voltage reading was all screwed up and I couldn’t make any sense of it. I pushed the potentiometer down and the RPM kicked in as they should have😀 The original cable from the throttle is kind of short and I must have pulled on it a bit too hard when I turned around,who knows?..
Electricity, electronics and programing are foreign to me. I didn’t want to fly without knowing how much juice was left in the Bonkas and risking damaging them. So, rigged a small voltmeter alarm to one of the four Bonkas (6S) since they deplete at just about the same rate and had about the same voltage to begin with. I mad enough wire length, wrapped them as one thicker cable which I attached to the throttle cable about 6" away from the handle. I set the alarm on the voltmeter to 3.8V. I have a bright red display of the cells 1 to 6 indicating one cell at the time their voltage. The sound on the small voltmeter is pretty loud and should warn me when it is time to quit.
Busted ground wire:
Weird display reading:
I hope it works!
