Waydoo eFoil — frequently asked questions

It's almost always debris in the propeller or a loose connector causing this. Immediately let go of the trigger, turn off the remote, lie flat on the board, and paddle back to shore. Then remove the battery and check the propeller and contacts. Never work on the propeller while the battery is still plugged in.

1. Let go of the trigger, turn off the remote, lie flat on the board and paddle back with your hands
2. On land, switch off and remove the battery — only then work on the drive unit
3. Check the propeller for sand/plants/string: remove the protective cap and propeller, clean them
4. Check that the Power Kit is seated firmly, tighten any loose L-screws
5. Check the metal contacts for saltwater/corrosion: rinse with fresh water, dry, use rust remover if needed, and reassemble dry

Heavy vibration where you can barely keep your balance almost always points to loose mounting screws on the Power Kit. Let go of the trigger, turn off the remote, and paddle back to shore lying down. Then take out the battery and retighten the mounting screws on the motor, mast, and wings.

1. Let go of the trigger, turn off the remote, lie down on the board and paddle back
2. On land: turn off and remove the battery
3. Check the mounting/L-screws on the motor, mast, and wings for tightness and retighten (approx. 5–10 N·m — value from the Flyer EVO manual)
4. Only reassemble and start once everything is securely tightened

Usually this is caused by a dropped Bluetooth connection, often after falling into the water. Let go of the trigger, turn off the remote, and paddle back. On land, check whether the Bluetooth icon is blinking: if so, restart the battery and pair again. If it stays unstable, contact support.

1. Let go of the trigger, turn off the remote, lie down and paddle back
2. Turn on the remote and check the Bluetooth icon — if it's blinking, there's no connection
3. Restart the battery and pair the remote again
4. For a stable signal, try to keep the nose of the board out of the water; don't cover the antenna inside the board (body/metal/water)
5. If the connection stays unstable: contact support

A red warning light on the battery indicates a protection function. Two red blinks means undervoltage (charge it), three means overtemperature (let it cool down), four means overcurrent (recovers on its own after about 30 seconds), five means short circuit (restart the battery). If the battery delivers no power at all, first check the connection to the Power Kit.

1. Red blink codes: 2× undervoltage → charge soon; 3× overtemperature → let cool down; 4× overcurrent → wait ~30 s, recovers on its own; 5× short circuit → restart the battery
2. No output (no steady blue light): check the connection between battery and Power Kit, retighten the L-screws
3. Fix the indicated cause, then turn the battery on again
4. If the error persists or other lights blink: stop using it, contact support

An "Err." code on the Controller Plus display reports an internal sensor or GPS error on startup. Err.1 means angle sensor, Err.2 means splash initialization, Err.3 means both, Err.4 means GPS, Err.7 means all failed together. Restart the remote and battery once. If the code stays, contact support.

1. Read the code: Err.1 angle sensor, Err.2 splash init, Err.3 angle sensor+splash, Err.4 GPS, Err.7 all failed
2. Turn the remote and battery off and back on
3. Don't go into the water while an Err. code is displayed
4. If the error persists: contact support

If the propeller doesn't respond to the trigger, the remote is usually in safety lock mode: if the trigger sits idle for a while (7 seconds on the EVO, 8 seconds on the Explorer/Patroller), it locks automatically. Hold the "−" button for about a second to unlock it. If the trigger is mechanically stuck, sand is often the cause.

1. Release lock mode: hold the "−" button for approx. 1 second (locks after 7 s of no movement, 8 s on Explorer/Patroller; the propeller also won't spin while in the settings menu)
2. EVO: don't hold the trigger while turning it on — otherwise you'll get a reduced throttle range; then restart or calibrate the trigger (long press "+")
3. Sticking trigger: rinse the trigger area thoroughly with fresh water while repeatedly pulling/releasing it to flush out sand
4. Let it dry and check that it works properly

Rinse all parts thoroughly with fresh water after every session — after saltwater this is mandatory, otherwise contacts and mast will corrode. First turn off the remote and battery, disassemble the battery, Power Kit, and wings, rinse the mast, motor, and propeller for about a minute, and clean the DC ports. Dry everything before packing it up.

1. Turn off the remote and battery, then remove the battery, Power Kit, front wing, and stabilizer wing
2. Rinse the mast body, mast head, motor, and propeller (guard) with fresh water for about 1 minute — no salt or sand should remain
3. Rinse the DC ports with fresh water and wipe them dry/clean with an alcohol swab
4. Rinse the board, battery compartment, and mast mount; stand the EPP board upright and let it dry completely
5. Rinse the remote (mind the trigger), wipe it with a dry cloth, and store it in a cool, dry place out of the sun

The battery contacts are the most important maintenance point: dirty or oxidized terminals increase resistance, get hot, and in a worst case trigger a protective shutdown. Clean the DC ports and terminals with an alcohol swab, rinse with fresh water after saltwater use, and only charge once the connectors are dry. Never use WD40.

1. After every session, clean the DC port and buttons with an alcohol-soaked cotton swab, then wipe dry
2. Check the terminals/contacts for corrosion every 2 months; remove buildup with alcohol
3. No WD40 or insulating sprays on the contacts — this worsens the connection
4. Only charge once the connectors are completely dry (otherwise electrolytic corrosion)
5. Hot, deformed, or corroded terminals: stop using it, replace the terminals or contact support

You can swap out a damaged propeller yourself — but only with the battery turned off and disconnected. Turn the protective cap clockwise to remove it, loosen the "bullet" from the motor shaft using a flat wrench or M4 Allen key, and take off the old propeller. Insert the new pin and propeller the right way round.

1. Turn off and remove the battery — only work on the propeller once this is done
2. Turn the propeller guard cap clockwise to remove it and detach it from the propeller guard
3. Loosen the "bullet" from the motor shaft using a flat wrench (EVO) or M4 Allen key (Explorer/Patroller), and take off the old propeller
4. Replace the old propeller pin with a new one, centering it in the crosswise hole of the motor shaft
5. Fit the new, undamaged propeller in the correct orientation (mind the groove), then reattach the bullet and protective cap

For breaks longer than a month, charge or discharge the battery to 40–60% — fully charged or fully drained both damage it. Store it somewhere cool, dry, out of the sun, never in a hot car, and never above 45 °C, ideally in a battery safety box. Clean and dry all parts thoroughly beforehand.

1. Clean all parts and dry them completely (see cleaning after a session)
2. Bring the battery to 40–60%; Explorer/Patroller: 'Healthy Charging' (press the charge button 4x) automatically stops at 80%
3. Store the battery cool/dry, out of the sun, never in a car, and never above 45 °C — ideally in a safety box/fireproof bag, separate from the board
4. Check the level about once a month (briefly hold the magnet to the button), recharge if needed to avoid deep discharge
5. Store the Power Kit, wings, and remote dry, clean, and out of the sun (original packaging)

Only charge with the original Waydoo charger in a dry, non-flammable location. Firmly connect the DC cable to the battery, then plug the AC cable into the outlet and start charging. A full charge takes around two hours; below 10 °C or above 45 °C, charging only starts once it's within the right temperature range.

1. Place the battery in a cool, dry spot away from flammable/hot objects; use the original charger
2. Firmly plug the DC cable into the battery port, lay the battery flat with the display facing up, then plug the AC cable into the outlet
3. Start charging: on the EVO via the start/stop button on the DC cable; on the Explorer briefly press the linking button (blue → green flashing = charging)
4. Fully charged after approx. 2 h — light turns solid green or the display turns off
5. Charging won't start below 10 °C or above 45 °C — move it to a temperature-controlled spot; never yank the DC plug out abruptly while charging; let it cool down after a session before charging

The Powerflight battery is operated with a magnet. To turn it on or off, hold the magnet against the power button for about three seconds until the logo and progress bar appear, or until the screen turns off. For a quick charge check, briefly tap the magnet once against the button while the battery is off.

1. Turn on: hold the magnet against the power button for approx. 3 s (within the ~1 cm sensor range) until the startup bar completes
2. Turn off: on the main screen, hold the magnet against the button again for approx. 3 s until the screen turns off
3. Check charge level: with the battery off, briefly tap the magnet once — the remaining charge appears, the display turns off after a few seconds
4. Explorer/Patroller: short + long press = on/off; blink codes indicate additional states (e.g. self-discharge)

Normally the remote and board connect automatically once both are turned on. If that doesn't work, pair manually: on the EVO, hold the power and „−" buttons together for two seconds, select the board, confirm with the trigger, and confirm on the battery with the magnet. On the Controller Plus, it's done via the linking button on the battery.

1. Turn on the remote first, then the battery — they often connect automatically
2. EVO manual: hold power + „−" for 2 s → Bluetooth list opens → select the board with „+"/„−" → confirm with the trigger
3. EVO: the battery signals confirmation is needed — briefly tap the magnet against the battery's power button; the Bluetooth icon lights up, control light turns green = connected
4. Explorer/Patroller: turn on the Controller Plus for 5 s; within 1 min, press the linking button on the battery short + long (a long beep = pairing mode); then hold power + „−" until the Bluetooth icon disappears = paired
5. New remote: turn off the old one first, then pair the new one

The flight assist automatically holds the set flying height — it only works on the Plus boards (Master/Pro/Max Plus) with a sensor. In the menu under „Flight Setting", switch from Manual to Flight Assist and choose high, medium, or low height. Check the sensor under the board's nose for debris beforehand.

1. Plus boards only: check the sensor under the board's nose for growth/debris
2. If the trigger is locked, press the power button → menu; press the trigger → menu item „Flight Setting"
3. Switch from „Manual" to „Flight Assist", then choose flying height high/medium/low
4. Gears: 24 levels via „+"/„−"; step size (1–4 gears per press) under Settings > „Gear setting"; beginners should start in gear 1
5. Only use the assist in calm water; turn it off in wind/waves

Err.1 means that during startup, the Controller Plus remote couldn't complete the initialization of its angle sensor — this sensor detects the tilt of the display. Turn the remote and battery fully off and back on. Don't head out on the water as long as the code is displayed. If Err.1 persists after the restart, the internal sensor is affected — in that case, support can help.

1. Turn the remote off and back on, restart the battery once
2. Don't go into the water while Err.1 is displayed
3. If Err.1 persists after the restart: internal sensor affected → contact support

Err.2 means the remote's „Splash" initialization failed during startup — an internal startup/self-test routine of the Controller Plus software. Turn the remote and battery fully off and back on. Don't head out on the water as long as the code is displayed. If Err.2 persists after the restart, it can't be fixed on shore — contact support.

1. Turn the remote and battery off and back on
2. Don't go into the water while Err.2 is displayed
3. If Err.2 persists after the restart: internal routine affected → contact support

Err.3 indicates that two internal routines failed at startup: the angle sensor initialization and the „Splash" initialization. Turn the remote and battery fully off and back on. Don't head out on the water as long as the code is displayed — the flight attitude sensing isn't reliable in that state. If Err.3 persists, the internal sensor system is affected and support can help further.

1. Turn the remote and battery off and back on
2. Don't go into the water while Err.3 is displayed
3. If Err.3 persists after the restart: internal sensor system affected → contact support

Err.4 means the GPS module in the Controller Plus remote couldn't initialize at startup. This mainly affects GPS-based readings like speed. Go outside with a clear view of the sky and restart both the remote and the battery once. If Err.4 persists even under open sky, the GPS module itself is affected — support can help with that.

1. Go outside with a clear view of the sky (not under a roof/dense trees)
2. Turn the remote and battery off and back on, let it search for GPS again
3. If Err.4 persists under open sky: GPS module affected → support

Err.7 is the combined error: the angle sensor, "Splash" initialization, and GPS all failed together at startup. Turn the remote and battery completely off and back on. Do not ride under any circumstances while this code is showing. If Err.7 persists after the restart, that points to an internal fault in the remote — stop using it and contact support.

1. Turn the remote and battery off and back on
2. Don't go into the water while Err.7 is displayed
3. If Err.7 persists after restarting: stop using the remote → support

Two red blinks means the undervoltage protection has triggered: the battery is too depleted and shuts off its output to protect itself. End your session, bring the battery safely ashore, and charge it soon with the original charger. Deep discharge permanently damages the cell, so don't leave it sitting. If it keeps blinking red after charging, stop using the battery and contact support.

1. End the session, paddle back lying down, safely remove the battery from the board
2. Charge the battery soon using the original charger (avoid deep discharge)
3. If it still blinks red 2× after charging: stop using the battery → support

Three red blinks means the overtemperature protection has triggered: the battery got too hot and shut off to protect itself. End your session and let it cool down in a cool, shaded spot before continuing to ride or charging it. Never charge a hot battery right away. If the code persists after cooling down, stop using the battery and contact support.

1. End the session, paddle back lying down
2. Place the battery in a cool, shaded spot and let it cool down — never charge a hot battery right away
3. If it still blinks red 3× after cooling down: stop using the battery → support

Four red blinks means the overcurrent protection has triggered: the battery briefly delivered too much current and shut off to protect itself. It usually recovers on its own after about 30 seconds. Wait a moment, then you can start again. If the overcurrent condition keeps recurring, check the propeller and drive for stiffness, and contact support if in doubt.

1. Release the trigger and wait about 30 seconds — the overcurrent protection usually resets itself
2. If it happens again, disconnect the battery and check the propeller/drive on land for debris and stiffness
3. If the 4× code keeps returning despite a free-running drive: support

Five red blinks means the short-circuit protection has triggered: the battery detected a short circuit and immediately locked its output. Restart the battery once (turn it off and back on). Before that, check the DC port and contacts for water, dirt, or damage. If it blinks red 5× again afterward, do not continue using the battery under any circumstances — this is a safety-critical fault; contact support immediately.

1. With the battery disconnected, check the DC port and contacts for water/dirt/damage, clean and dry them
2. Turn the battery off and back on to reset the short-circuit protection
3. If it blinks red 5× again afterward: safety-critical — stop using the battery, contact support immediately

Assemble in this order: connect the propulsion unit and mast, screw on the front wing and stabilizer, then insert the battery and secure it with the twist locks. Check all DC ports for water and dirt beforehand. On the EVO, tighten the screws to around 5 to 10 Newton meters; the Explorer manual doesn't specify a fixed value.

1. Before assembly, check the battery compartment and DC ports for water/sand/dirt, clean and dry if needed
2. Place the mast vertically onto the propulsion unit and screw it on (EVO: 2× M6x20, 5–10 N·m; Explorer/Patroller: L-screws); turn the board over, insert the mast into the mast mount and tighten
3. Screw on the wings using original screws (EVO: front wing 3× M6x35, stabilizer 2× M6x20, each 5–10 N·m; Explorer/Patroller: stabilizer 2× M6x15, front wing 2× M6x24, 4mm hex key)
4. Insert the battery into the compartment and secure it with the twist locks (EVO: ~90° clockwise; Explorer/Patroller: turn both locks 180°)
5. Turn on the remote control first, then the battery, and check the connection

Start in calm, deep water wearing protective gear. Climb onto the board from behind, unlock the remote control with a long press on the minus button, and pull the trigger slowly. Ride lying down first, then kneeling, then standing. Beginners start at gear 1 on the EVO, and below gear 5 on the Explorer/Patroller; you can take off at around 15 km/h.

1. Put on protective gear (wetsuit, shoes, impact/floatation vest, helmet); check water depth and surroundings; the propeller briefly spins at its lowest setting before entering the water — keep hands/feet clear
2. Climb onto the board from the back, use the board handle, don't step on the wing/propeller; a spotter is recommended
3. Select a low gear: EVO beginners gear 1, Explorer/Patroller below gear 5
4. Unlock the remote control (hold minus button ~1 s), pull the trigger slowly, shift weight slightly forward
5. Take off once speed and pitch are right (Explorer/Patroller from approx. 15 km/h); steer height/direction using weight and trigger

Charge the remote control using the included magnetic charging plug on a USB power adapter. Position the magnetic plug so the charging pins make contact; the indicator light shows charging status. The EVO remote is fully charged after about two hours (5V/2A adapter), the Controller Plus after about three hours. Below 20 percent a warning appears — charge it soon after that.

1. Plug in the USB power adapter and attach the magnetic charging plug to the charging surface of the remote control (charging pins must make contact)
2. The indicator light on the underside lights up when charging correctly
3. Charging time: EVO remote approx. 2 h (5V/2A), Controller Plus approx. 3 h until full
4. Low-battery warning below 20% — charge the remote control soon after

Only ride on open, deep water wearing a life vest and helmet, well away from swimmers, boats and obstacles, and never in bad weather. The EVO needs at least 1.5 meters of water depth, the Explorer/Patroller at least 1.2 meters. Watch the payload limit — for the Explorer max. 100 kilograms — and follow local regulations.

1. Water depth: EVO min. 1.5 m, Explorer/Patroller min. 1.2 m; watch out for gravel, plants and animals in the water
2. Keep your distance from the shore, swimmers, divers, boats and obstacles; don't ride in crowded areas or zones with traffic restrictions
3. Protective gear: impact vest/life vest and helmet, plus a wetsuit is recommended
4. Don't ride in rain, thunderstorms, fog, strong wind or in currents
5. Respect the payload limit (Explorer/Patroller max. 100 kg; don't exceed the manufacturer's limit for the EVO) and comply with local laws

If the Explorer or Patroller battery isn't charging, press the power button briefly six times — it will show the cause via a blue blink code: three blinks means full, four means charging target 80 percent, five means charger error, six means battery self-protection, seven means non-battery error, eight means overvoltage lockout. Also check the charger, plug and connections.

1. Press the power button briefly 6× to query the error cause
2. Blue blink codes: 3× fully charged; 4× charging target 80% (Healthy Charging); 5× charger error; 6× battery self-protection; 7× non-battery error; 8× overvoltage protection blocks charging
3. Check the charger: red blinking light = defective; firmly connect AC/DC plugs; toggle switch on the charger set to ON
4. Red fault indicator on the battery or persistent error: stop charging the battery, contact support

If your Flyer ONE Plus gets stuck at gear 4, it's usually because it hasn't been activated in the Waydoo app yet — do that and all 24 gears will be unlocked. Via the Controller Plus settings you can also select a Speed Limit mode with a maximum of 10 gears and an adjustable top gear. The EVO also offers 24 gears.

1. Gear 4 lockout: activate the Flyer ONE Plus in the Waydoo app — without activation it's limited to gear 4
2. Open settings: on the Controller Plus while powered on, briefly press "+" and "−" simultaneously; navigate with "+"/"−", confirm with the power button
3. Under "Mode" turn Speed Limit mode on/off; when active it limits to 10 gears, with an adjustable top gear
4. Select unit (km/h or mph) and language in the same menu

Never transport the board loose on the car roof — it can slide off. Use the wheeled bag (Explorer/Patroller) or the Mover trolley (EVO). Important: the battery must not be inserted in the board while carrying it or on bumpy paths or stairs. Transport the battery itself according to the applicable regulations.

1. Never transport the board unsecured on the car roof (risk of slipping and falling)
2. Explorer/Patroller: use the wheeled bag — pack the Power Kit, battery, wings and controller, secure the board with the straps
3. EVO: mount the Mover-S (Pro/Pro Plus) or Mover-L (Max Plus); on bumpy paths/stairs don't leave the battery on the board (the Mover pole could break)
4. Before carrying, switch off the remote or lock the trigger; avoid bumping the propeller and wings
5. Transport the battery separately and in accordance with local regulations for lithium batteries
