I had one like that back in the late 50s, it ran on two D cells. It had a rudder arm that you could set. Eventually tried increaseing the speed by increaseing battery voltage, fried the engine. Ended up putting a fox 0.49 glow engine in it, which made it a fast runner. Never did try RCing it, was too small for the gear available. Eventually gave it away and kid that got it lost it. Wish I had kept it now especially the engine.

Gerald.
