How to choose ESC Version?
1) MTSF300A-WP with Internal Receiver: Can only work with Maytech remote MTSKR1905WF, the wiring had been wired by our engineer, more convenient to use.
If you put the ESC near the top of your board and can lead the receiver terminal out of water, then you can choose this version.
(Standard lead out antenna length is 10cm, we also have 1m antenna and 3m antenna, if you need to put longer antenna into the ESC, please order the antenna length you need here: 1m/3m Antenna , leave a note that you want to put longer antenna into ESC)
2) MTSF300A-WP No receiver: Can work with other receiver and remote, more flexible.
If you will put the ESC at the bottom of your board and underwater, suggest to choose this version.
Please noted for usage:
Max ERPM recommended to use for the ESC is 50000.
ERPM = RPM x Motor pole pairs number
