I have a brand new BlueROV2 that I am putting the final touches on. I’ve armed it and testing all the motors. A couple were spinning the wrong direction which was easy to change in QGroundControl but the port side vertical thruster is stuttering and never getting up to speed. I’ve detached and reattached all the connections inside. Not sure what else to do. My starboard front thruster also was generating very little air movement but appears to actually be spinning unlike the vertical one. Again, brand new, never been in the water. Just a couple arm tests today.
