[PSUBS-MAILIST] "Torpedo"-build

[hank pronk via Personal_Submersibles]

Lasse,I have experimented with air drills as thrusters on a log salvage ROV and it worked well, as long as you add an exhaust pipe to the drill.  The exhaust air must be carried away from the propeller.  This works but the drill will not last long, it is the gear box that fails.  I would suggest a smaller prop and go with a die grinder or any air tool with no gear head.  The vane motor will last a long time.Hank

 Hey guys,
My crew friends at submarine Malen are planning to build a torpedo-ish machine to fool around with in the evenings. We are thinking of taking a scuba-tank, connecting a simple motor from an air drill and connecting a propeller to it. We are planning to use RC for steering and heading hold via a gyro. Have anyone tried and have input on this?
Cheers, Lasse
