We didn’t know a submarine airplane existed either, until we saw this incredible video. This unique RC model doesn’t just take off and soar through the skies; it dives beneath the surface too! Equal parts airplane and submarine, it’s a brilliant example of the creativity and innovation that make this hobby so much fun. Whether it’s skimming above the water or disappearing below it, this quirky machine delivers nonstop entertainment. We love seeing designs that push the boundaries of what’s possible in RC!
Submarine Airplane? Yes, Really!
That is cool. cg was crap for sure. I was working with a guy some years back that was developing a ultrasonic telemetry system for under water. I think it would possibly be a great way to control the plane in sub mode. It’s been in the back of my head for a while to build an underwater vehicle run on this system. Only two controls needed under water as you need to surface to empty the bilge / float tanks. Or go full nerd and compress some air to to be used to empty the floats. I have no idea what a small compressor costs or weighs. Other thought was move the rear prop motor well forward on a shaft. or why not move it too a pod in he conning tower.
Ask any r/c sub guy, they’ll tell you to use any longer wave length r/c frequency, i.e. 27 mHz, 72mHz or 75 mHz. They all work fine in fresh water. DO NOT use them in salt water.
A better design for a Sub-Plane would be to get rid of the pontoons and go to a seaplane design called a flying boat. The fuselage bottom is a planning hull with a step like the pontoons. It is easier to build, less complex and less drag.
Very well thought out and engineered. As said above CG needs to be addressed, this is what causes the rocky motion from side to side. Fun to watch the video!!
