My system is based on a Raspberry Pi controller + two T200 thrusters and related BlueRobotics ESCs.  
It is powered by a 4S LiPo battery, with a DC/DC converter providing 5V power supply for the controller.

I want to perform some preliminary tests out of the water before assembling the whole system.  
Do T200 thrusters and ESC have any limitation working out the water? Any advise or suggestions?

thx  
Andrea

Hi Andrea,

The T200 thrusters should only be run out of the water for very short pulses. Maybe one second or two. MAX!

The ESCs will be fine under pretty much any condition.

Good luck with your build!
