David,
How did you manage to squeeze in 2 280 DC motors into the 2" SD? The 280 motors have an outside diameter of 24mm, so 2 of them side by side is 48mm. Given the walls of the SD to be 1.5mm thick that leaves an nside diameter of 47 mm, a 0.5mm excess both sides.
"All hands rig for depth charge!"
