Andy,

there is a youtube video (at least one) that I viewed some time ok and it showed an MTB, about 36",  being sailed on a canal. The modeller had made working torpedoes, yes complete with internal batteries and counter rotating propellers to drive them. His video showed them being fired towards himself from about 30 metres out and his sudden ducking down to catch each as it sped through the water to the canal side. They were fast and looked substantial. Not sure of his launching mechanism, but the engines engaged as soon as they left the pods. No sound Ashley, so cannot comment on a whether a "woosh or a plop"!

I'm sure a web search would turn it up, I was looking as I'm converting the PT-109 to r/c and want some extras to function – gun turrets and torp tubes rotating, but actually firing torpedoes, maybe not enough weight tolerance in the small hull. As it is I've almost used all weight up in fitting 3 x brushless motors with separate escs and a control board. Now making small rudders, larger than supplied but big enough to give some steerage, and using a single small servo.
