It is designed for water sports use including eFoil, electric surfboard, and kayak applications in both freshwater and saltwater. The internal large-cavity design also allows the remote to float naturally if dropped in water — no float rope required. Rinse with fresh water after saltwater use to extend service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: Which ESCs is the VX5 compatible with?\u003c\/strong\u003e\u003cbr\u003eThe VX5 supports VESC, FTESC, FOCBOX, and PPM-based ESCs. It is fully compatible with the Firduo Manatee 100 Pro VESC via UART or PPM connection.

Charge using the included cable; the display shows real-time charging power so you always know the status. A full charge from empty takes approximately 2–3 hours. The built-in high-precision battery meter shows remaining charge accurately on the display.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What's the difference between Surfboard Mode and E-Skateboard Mode?\u003c\/strong\u003e\u003cbr\u003eSurfboard Mode is optimized for water sports — it supports up to 20 power levels for fine-grained speed control, which is critical for eFoil balance and wave riding. E-Skateboard Mode uses L\/M\/H gear switching with configurable throttle percentages, better suited for street riding where quick gear changes are more important than fine power gradation. Both modes support throttle curve presets and auto-lock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I update the firmware, and how?\u003c\/strong\u003e\u003cbr\u003eYes. The VX5 supports OTA (over-the-air) firmware upgrades — no cables or special tools required. Connect to the upgrade portal via the VX5 app or follow the instructions in the manual. Firmware updates add new features, fix bugs, and improve ESC compatibility. We recommend checking for updates after initial setup and periodically thereafter.\u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/18_cabbf6e5-820f-40cb-b4df-d0ca43dbaa43_1024x1024.jpg?v=1761722016\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e","brand":"Firduo","offers":[{"title":"Black","offer_id":46660732190898,"sku":"VX5-1","price":249.0,"currency_code":"USD","in_stock":true},{"title":"Transparent","offer_id":46660732223666,"sku":"VX5-2","price":249.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/10_dcb14a6e-791c-4d77-9e1b-2c88b880a200.jpg?v=1761723065"},{"product_id":"firduo-sensorless-brushless-motor-fully-waterproof-motor-56115-150kv-2400w-for-surfing-boat-underwater-thruster-hydro-efoil","title":"Firduo Waterproof Brushless Motor 56115 150KV 2400W for Efoil \u0026 Underwater Thruster","description":"\u003ch3\u003e🌊 Compact.

The \u003cstrong\u003e65111\u003c\/strong\u003e (65mm diameter) offers 2KW peak in a slightly larger package, and the \u003cstrong\u003e65162\u003c\/strong\u003e (65mm, 162mm length) delivers 7.2KW for high-performance eFoil and heavy-rider builds.

The 56115 is rated \u003cstrong\u003eIP68\u003c\/strong\u003e — fully sealed for continuous underwater operation in both fresh and saltwater. The motor relies on natural water flow for passive cooling during operation. Avoid running the motor out of water for extended periods at high power, as the passive cooling depends on water flow. Brief out-of-water testing at low power is acceptable for connection verification. After saltwater use, rinse with fresh water to remove salt residue.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: What propeller should I use, and what does the Motor + Propeller variant include?\u003c\/strong\u003e\u003cbr\u003eThe \u003cem\u003eMotor + Propeller\u003c\/em\u003e variant includes a matched propeller optimized for the 56115's thrust curve at 48V.

The \"Motor + Propeller\" variant adds a matched 140×120mm 2-blade propeller designed for the Φ10mm long-thread shaft. If you already have a compatible propeller or are using a custom prop, choose the Motor-only variant.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ2: What ESC is recommended for this motor?\u003c\/strong\u003e\u003cbr\u003eThe Firduo Manatee 100 Pro (75V 100A VESC-based ESC) is the recommended pairing. It supports FOC mode, handles up to 100A continuous (150A peak), and covers the full 6S–16S voltage range of this motor. For higher-power builds at 16S, ensure your ESC is rated for the voltage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ3: Is IP58 sufficient for eFoil \/ continuous underwater use?\u003c\/strong\u003e\u003cbr\u003eYes. IP58 means the motor is rated for continuous submersion beyond 1 meter depth — suitable for eFoil, underwater thrusters, and ROV applications. The ceramic bearings are specifically chosen for corrosion resistance in both fresh and salt water. Rinse with fresh water after salt water use to extend bearing life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ4: What battery voltage gives the best performance?\u003c\/strong\u003e\u003cbr\u003eFor most eFoil and thruster builds, \u003cstrong\u003e12S–14S (44–52V)\u003c\/strong\u003e is the optimal range — this puts the motor in its peak efficiency band (see characteristic curves above). At 16S (60V) you get maximum power but higher heat; at 6S–8S the motor is underpowered for eFoil use. The characteristic curves at 36V and 48V are shown in the spec section above.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ5: Can I use this motor for a dual-thruster setup?\u003c\/strong\u003e\u003cbr\u003eYes. Two 6384 motors can be run from separate ESCs connected via CAN bus (if using VESC-based ESCs) for synchronized dual-motor control. Each motor draws up to 88A peak, so ensure your battery and wiring are rated for the combined current. A dual setup is common in twin-thruster kayak and USV builds.\u003c\/p\u003e\n\u003ch3 style=\"margin-top: 20px;\"\u003e🏄 Application Scenarios\u003c\/h3\u003e\n\u003cdiv style=\"text-align: center; margin: 16px 0;\"\u003e\u003cimg style=\"max-width: 100%;\" alt=\"Firduo 6384 motor application scenarios efoil surfboard thruster\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/430a96078c80bcde95dde4af4378318c.jpg?v=1761804452\"\u003e\u003c\/div\u003e","brand":"Firduo","offers":[{"title":"Motor","offer_id":46663421067442,"sku":"6384-1","price":129.0,"currency_code":"USD","in_stock":true},{"title":"Motor + Propeller","offer_id":46663421100210,"sku":"6384-2","price":159.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0227\/7805\/2685\/files\/4_3d69fcb9-4069-405d-871f-fe4b42f90ce4.jpg?v=1761787842"},{"product_id":"firduo-tuna-thrust-system-1500w-18-5kgf-electric-fin-for-sup-surfboards-kayaks-rov-auv-usv","title":"Firduo TUNA thrust system 1500W 18.5KGF Electric Fin Thruster for SUP \u0026 Kayak","description":"\u003ch3\u003e🌊 All-in-One Electric Propulsion.

The TUNA A1 uses a \u003cstrong\u003epassive water-cooled tube\u003c\/strong\u003e that draws water through the motor housing as the thruster moves through water — no pump or external cooling loop required. This keeps the motor cool during normal operation. Avoid running the thruster out of water for extended periods, as the passive cooling relies on water flow.
