Also, regarding bad connections in the control head, here's what I've done to repair mine.
It would occasionally turn hard to port or starboard for no apparent reason especially after a long time of use, then slowly go back on course if I didn't manually correct it.
The fix was resoldering nine out of a possible twelve bad connections to four power transistors in the head unit.
Each transistor has three leads. The transistors get warm during use and eventually the solder connections crack from stress.
The cracks are very small, but that's all it takes to give problems.
The transistors are all mounted around the middle of the board and are probably black in color.
