This is my much modified Darnell P class boat, built to represent HMCS(Her Majesty's Canadian Submarine)Onondaga(my girlfriend is Canadian, hence the link to her home country...)
Onondaga was the test boat for a unique dive system Bernie Wood designed, she had a 540 motor in a tube, dead centre of the hull, the idea being that the motor would drag the boat down. This was coupled to a modified R&R Engineering SALCON(Submarine Automatic Level Control)which controlled not only the rear planes(via a servo)but the speed controller for the dive motor...as the SALCON detected a change in the boat's attitude underwater, it would send a signal to the rear plane servo to correct the difference in level and also give the dive motor a short burst of power(either up or down)to keep the boat level.
It worked to a point, but the battery drain was horrendous, so after a while Onondaga was converted back to the more usual Darnell air system, and fitted with ex-tyre compressor instead of the little USE steam engine as an air pump.
