Product Description
U Series
Bidirectional control brushless underwater thruster
Functional Features
MU7/MU7 PRO BRUSHLESS THRUSTER
————————————————————
● MU7/MU7 Pro uses aviation aluminum alloy, which has the advantages of high strength and light weight;
● Equipped with two-way waterproof ESC, it has multiple protections:
low voltage protection, over-temperature protection, stall protection, etc.
● Uses ultra-soft 3-core silicone wire, which is simple and uncluttered and convenient for users to use;
●Waterproof depth of 200 meters.
U8 BRUSHLESS THRUSTER
———————————————
●U8 adopts an integrated mold design, high-strength composite materials, and a delicate and exquisite surface;
●Adopting modular design, customers can flexibly install the protective net according to their actual situation;
●Two-way electric adjustment can realize the forward and reverse operation of the propeller, epoxy resin glue sealing, more efficient heat dissipation in water, and can maintain the propeller stable operation for a long time;
● U8 is equipped with a protective net to prevent water plants, garbage, etc. from entangled with the propeller. (Note: After installing the protective net, due to resistance problems, the propeller efficiency will be reduced by about 20-35%.)
