Description
Electrofin - underwater thruster for FatJay F4125 brushless motor.
Fits inflatable StandUpPaddleboard or kayak.
Cheap analog of AquaMarina BlueDrive Power Fin, Current Drives Electrafin, etc
Not tested for maximum speed yet.
Inspired by bluerobotics T200 thruster.
RC: 18650 / Nano / nRF24 / WS2812 / Potentiometer
Motor: F4125 / 6s4p battery / ESC 6s 70A / Nano / nRF24
Update:
Finally I've tested it. Thruster gives 5-6km/h and more than one hour range.
For FatJay F4125 it is better to have 100amps ESC. 70amps ESC got overheated on full speed and stops.
