I've just finished building my v2.5 and had my first test dive in the swimming pool today. All went pretty well except I'm having trouble with control.
I had to add some weight to get to slight positive buoyancy. Now when I thrust forward, the rov dives at about a 15 degree angle. When I try to descend using the vertical thruster, the rov tips backward, points vertical and actually travels forward.
Is this just a centre of buoyancy issue?
