Features: Designed for RC boat, giving fastest response of the motor. Water cooling system can dissipate heat and reduce noise for your model. Waterproof design ensures the safety of component and extends its service life. (Need to use 704 silicone rubber by yourself). It comes with a limited range of programming functions and are designed to be plug-n-play. It consists of high quality components to get strong current endurance. Specification: Material: PBC Color: Black Size: Approx. 9.5 * 3.8 * 2.5cm / 3.7 * 1.5 * 1inch Cont Current: 200A Burst Current: 230A BEC Model: Switch BEC Output: 5V, 5A Recommend Battery: Li-ion/Lipoly 2-7S Ni-Mh/Ni-Cd 6-20NiMh (Not Included) Cooling: Watercooled Weight: 140g Type: RC Part Package Includes: 1 x ESC 1 x Manual Note: Enter programming Mode: 1. Connect your motor and receiver to the ESC, but do not connect the battery yet. 2. Turn on your transmitter and move the throttle stick to the full. Please note: for futaba most transmitter have the throttle channel reversed by default. 3. Connect you battery and controller, which will initialize with a musical tone. Phrases 2 programming: After 3 seconds, the controller will start beeping a sequence of tones followed by one or more beeps. Each sequence represents a parameter that you can program and it repeats 3 times. The parameters are: Music tone 1 beep: cell type and No. of cells Music tone 2 beep: throttle setting Music tone 3 beep: brake setting/throttletype (for Heli) Music tone 4 beep: direction and Cutoff Type Music tone 5 beep: timing mode User programming options: Cell Type: NiMH/NiCD/Lipoly/Li-ion Cell Quantity: 2S-7S/6-20NIMH Throttle Setting: Auto/Soft/Hard Brake: No Brake/Soft/Medium/Hard Direction: Clockwise/Counter Clockwise Cut off: Soft/Hard Timing: 1o/7o/15o/30o PWM: 8Khz/16khz1Designed for RC boat, giving fastest response of the motor 2Water cooling system can dissipate heat and reduce noise for your model 3Waterproof design ensures the safety of component and extends its service life.
