Yeah, that could work, too. It really depends on what morphology is chosen in the end. If the vehicle looks like a quadcopter, then changing the signs would be all that's necessary. It just wouldn't be a very good UUW!

Hi mate.

I think its a waste of time to use motors and propellers designed for air in water.
I have made severals RC submarines, and best results archived with a cc motor and a proper propeller.
Also I don't understand why to use a quad frame to do this. Take in mind presure under water !!! Best idea are pipe frame or spheric.
Another problem will be radio signal. The radio signal on Ghz, even Mhz its not valid for water if u want a significant range.
On water, movements and so happens very slow than on the air. Take in mind.

If u need ideas or even plans to make a RC sub, I have some ones useing pipes and cc motors.
Also can advice with electronics, that are much easyer than CopterControl,

Brushless motors dont fits your needs.

Regards.
