Turnigy AquaStar 240A Water Cooled ESC

Description

The Aquastar 240A HV Water cooled ESC is a high quality ESC designed from the outset for serious boat racing.
It is a microprocessor controlled, high voltage, ultra-low resistance (0.75m?) Opto speed controller for 4 to 12s LiPoly batteries (up to 38 cells NiMH/NiCad) and uses 8 AWG wires (min 8mm connectors required) for maximum operating efficiency.
A unique feature of the Aquastar 240A is the integrated cooling plate between the MOSFET boards. When coupled with the dual cooling inlet/outlets this keeps the ESC cool under the most demanding loads.
This ESC has 8 programming options for flexibility, on-board data logging, 300A surge capacity, adjustable switching rate and many more class leading features.
Programing can be done with your transmitter, programming card or optional USB adapter
