I have finished everything thanks to Mr. David Boulanger, Mr. Dave and Mr. Rmackay9(I’am writing your names in the acknowledgement of my report)
Issue is about ESC’s sync. When i move the throttle up a little bit port motor starts working at a slow speed. starboard doesn’t work. then if i move a little bit further both motors work fine. I have calibrated the radio but I will do it again now.
I have never ever calibrated them. I just plugged them to pixhawk. And there was no such issue. Left shafts dog bone had a friciton issue(choric issue in this boat). Maybe the ESC or pixhawk tried to compensate it? I have succesfully changed the shafts with a ball bearing one that can do reverse(props with nuts original props didn’t have nuts and designed for only forward).
So both shafts work well with no issues.
should i perform an ESC calibration? Or can i simply use trims in Mission planner?
I have no reference guide of the ESC’s but they beep when I arm.
note: originally the motors had 104 ceramic capacitors, 1 in each terminal. But unfortunately while dissembling the port side motor , I broke one. so the starboard only has 1 capacitor. I couldn’t find any to replace. https://drive.google.com/open?id=1O60edgKxXv6BGzPpXF1K2SVYCZ93HkJz
solution: one motor’s 100nF capacitor was borken I replaced it. so each motor has 2 100nF capacitors. How they do work at the same time. works like a CHARM!
