Technical Guide

Top speed depends on the configuration:

• EVO Lite: up to 36 km/h (22.4 mph)
• EVO Max Plus: up to 45 km/h (28 mph)
• EVO Pro Plus: up to 52 km/h (32 mph)
• EVO Master: up to 52 km/h (32 mph)

Actual speed varies with rider weight, water conditions and your setup.

The EVO Max Plus, Pro Plus and Master are rated up to 120 minutes on the 2300 Wh pack. The EVO Lite is rated up to 100 minutes.

In practice, expect 45 to 90 minutes or more depending on your weight, how hard you ride, water conditions and which gear you use. Riding at full throttle in chop will always draw more than cruising.

These are the ideal rider weights for each configuration:

• EVO Lite: up to about 90 kg (198 lbs)
• EVO Max Plus: up to about 130 kg (286 lbs)
• EVO Pro Plus: up to about 130 kg (286 lbs)
• EVO Master: up to about 100 kg (220 lbs)

Heavier riders are generally steered towards the Max Plus regardless of experience level, because the 130 L board carries more volume and lifts more easily.

The Subnado Lite and the Subnado Plus are both rated IP68 to a depth of 60 metres.

Keeping that seal intact depends on maintenance. Apply a small amount of grease to the green O-rings on the cable connector regularly, and avoid taking the unit apart after every session. That wears the O-ring faster than anything else.

• Thrust: 33 kg
• System weight: 5.6 kg
• Battery: 432 Wh at 43.2 V
• Charging time: 2.5 hours
• Unit dimensions: 42.5 x 16.5 x 8 cm
• Mounting: under the board

For mounting and board compatibility, work from the FoilBoost manual. It covers the fitment detail properly.

Subnado Lite: 1.4 m/s with a single unit, over 2.0 m/s running two. Up to 56 minutes, with a 50-second Super Gear burst.

Subnado Plus: 1.7 m/s with a single unit, 2.4 m/s running two. Up to 60 minutes, with a 150-second Super Gear burst.

Both have three gears: Low, High and Super Gear. Run time depends on which gear you use, how deep you are and how much you are carrying.

The Master is the performance-focused configuration in the EVO line. It runs a 75 L board built with Kevlar and carbon fibre, a one-piece moulded carbon mast and a CNC fuselage, which makes it lighter and more responsive than the other boards.

That translates into sharper handling and more direct control at speed. It reaches 52 km/h (32 mph) and uses a 31 inch mast. It suits advanced riders who already have solid foil control and want precision, rather than riders still learning.

The Waydoo app is free on both platforms. Search for "Waydoo", or use these links: Waydoo app on the App Store or Waydoo app on Google Play.

The app is used for GPS ride data, firmware updates and registering your Subnado for extended warranty.

No. The Subnado is operated with a wired thumb controller, which is included in both the Standard package and the SUP Kit. A wireless remote is a Flyer EVO feature. The Subnado does not use one.

Flight Assist uses sensors and gyroscope inputs to help stabilise lift and assist throttle control while you are flying. It shortens the learning curve considerably.

It is fitted to the EVO Max Plus, EVO Pro Plus and EVO Master. The EVO Lite does not have it.

It can be toggled on or off. Beginners usually leave it on while learning; more experienced riders switch it off for full manual control and a more engaged ride.

Around 10 to 15 minutes once you are familiar with it. The EVO is designed for modular assembly and every tool you need is included in the set, so there is nothing extra to buy.

Your first few assemblies will take longer. The assembly video below walks through the whole sequence.

Yes. Every EVO configuration is modular within the same system. You can swap or upgrade wings, masts, propulsion units and batteries, and you can mix components from other EVO models to tune the ride to your style.

This means you can start on a setup that suits you now and change it as you progress, rather than replacing the whole eFoil.

Yes. The Epix E-Foil works with the EVO line masts, wings, propulsion units and chargers, so you can adapt or upgrade the setup as your riding develops.

Yes, but it takes effort. The adhesive mounting base is a strong bond, rated to hold against 50 kg of force, so removing and reapplying it is not a quick peel-and-stick job.

The good news is that the box includes several mounting stickers. If you use the Subnado across a few different boards, you can fit one sticker per board rather than buying an extra mounting kit.

Every current manual is linked below. If you are not sure which Subnado you have, check the length. The Lite is 377 mm and the Plus is 397 mm.

Both are straightforward jobs with an official video for each.

If the mast itself is structurally damaged rather than just needing a new head, do not work on it. File a claim instead.

Ride and track data comes off the board through the Waydoo app. The videos below cover getting your track data, uploading the MAST log, and the HF22 log procedure.

If you are working through a fault with us, pulling the logs and attaching them to your claim is one of the most useful things you can do. It often tells our team what happened without any back-and-forth.

The Mover is the transport trolley for moving your setup to and from the water. The assembly video below runs through it end to end.

The Mover is sold separately from the eFoil. The EVO Max Plus uses the larger Mover (L).

There is a short video for each mount and accessory. Pick the one you need from the list below.

If you are setting up for the first time, start with How to use the Subnado, then fit the finger safe-guard before anything else.

The video below covers the remote's function setup, including calibrating the throttle trigger.

Trigger calibration is also the fix if you see an angle overflow message. That appears either because of magnetic interference, in which case restart the remote, or because the throttle travel no longer matches, in which case recalibrate.

The Flyer ONE and ONE Plus are earlier generations and are no longer sold as complete units, but the manuals are still available and we still support owners. They are linked below.

For a fault or a spare part, file a claim as normal and tell us which model you have.

The official installation guide video below walks through fitting the Jet Drive.

If you are unsure whether the Jet Drive fits your setup, check with us before fitting rather than after.

It depends which model you have, and you should always confirm with your airline before you travel.

• Subnado Lite: 98 Wh, which sits under the 100 Wh threshold most airlines apply to lithium batteries in carry-on baggage.
• Subnado Plus: 144 Wh, which is above 100 Wh. Batteries between 101 and 160 Wh normally require prior approval from the airline.

Rules differ between carriers and routes, so check with your airline in advance. We can supply the UN38.3 test report and MSDS documentation if they ask for it.

About 1.2 hours for a full charge on both the Lite and the Plus, over USB-C.

The Lite charges at up to 100 W (PD3.0) and can also work as a power bank. The Plus supports 140 W bi-directional fast charging (PD3.1).

Topping up with a lower-power charger is fine, particularly when the unit is already showing five or six bars.

Stop here first: if the battery is swollen, hot, wet, leaking or physically damaged, do not charge it and do not test it. Go straight to a warranty claim.

Otherwise there are three safe checks worth doing:

1. Fit the battery to the board, power on, and confirm the board runs when you pull the remote trigger. That tells us whether the pack is holding charge at all.
2. Check that the two screws on both the charger plug and the battery terminals are not loose.
3. Wipe the infrared sensors on the battery and the charger with alcohol. They communicate optically, and a smear is enough to interrupt it.

If it still will not charge, file a claim and attach a 30-second video showing the charger indicator, the battery screen and the button on the DC cable in the same frame. That one video usually tells our team what is wrong.

Stop using it and stop charging it immediately. This applies if the battery is swollen, unusually hot, smoking, leaking, has got wet, or has been dropped or physically damaged.

Move it away from anything flammable and leave it alone. Do not try to test it, discharge it or charge it to see what happens.

Then file a claim and tell us what happened. Mark it as urgent, because our team treats battery damage as a priority case.

Two safe checks:

1. Try a different charger and cable. If it takes charge, the original charger is the problem.
2. Look into the charging port for corrosion or burn marks.

If it charges but stops before full, unplug and replug into a different charger a few times and see whether it resumes. Topping up on a lower-power charger is fine when it is already at five or six bars.

If neither helps, file a claim and describe what you saw.

This is usually a seating or gasket issue rather than a fault. Pick the clip that matches what you are stuck on:

• Installing the battery compartment plate
• Installing the battery itself
• Taking off the rubber plug
• Removing the rubber gasket

If anything looks damaged or is missing while you are in there, stop and file a claim so we can send the replacement part.

Isolate which part is at fault before anything else:

1. Try a different charging cable, or charge a different remote with the same cable.
2. Look into the charging port for corrosion or damage.

If the remote still will not power on normally, file a claim rather than opening it.

Yes. Our products contain lithium batteries, and carriers, customs officials and airlines sometimes ask for the paperwork. Both documents are below.

The UN38.3 test report covers transport testing; the MSDS covers material safety.

Cover runs from the date you receive the product, and the length depends on the part rather than the whole product.

Flyer EVO and Flyer ONE

• Mast and propulsion unit: 2 years in Europe
• Board: 1 year
• Wings: varies by region, so check the full terms

Subnado in Europe

• Main unit: 2 years
• Rear cover and charger: 6 months

The warranty covers defects in material and workmanship under normal use, following the official instructions. Impact damage, unauthorised modification or disassembly, improper installation, use in unsuitable conditions, third-party parts and altered serial numbers are not covered. The full terms are linked below.

Registering a Subnado on the Waydoo app adds three months to its cover.

No. You can use it straight out of the box, with no registration required.

Registering it on the Waydoo app adds three months of extended warranty. That is the only reason to do it, and it is entirely optional.

You have 30 days from receipt to request a return.

To be accepted, the item needs to be unused, in its original packaging, with all accessories, manuals and components, plus proof of purchase. Used, damaged or incomplete returns may receive a partial refund or be refused.

Anything that has been used in water is not returnable unless it is defective. The same applies to misuse damage, items missing essential parts, and final-sale items. None of this affects your statutory warranty rights.

Yes. If you are in the European Union you have a statutory right to withdraw from your purchase within 14 days of delivery, without giving a reason.

Notify us within 14 days of delivery, then return the product within 14 days of notifying us. It needs to be unused and in resellable condition.

This sits alongside our 30-day return window rather than replacing it, and it does not affect your statutory warranty rights.

Return shipping is at your cost in most cases.

Where the item arrived damaged, is defective, or we sent the wrong product, we cover it. We will either provide a prepaid return label or reimburse reasonable shipping costs.

For international returns you pay the return shipping and any customs charges, and refunds exclude import duties and taxes, unless the cause was our error or a defect.

Email return@waydoo.tech with the subject Return Request - Order #, including your order number, the items you want to return and the reason. We will reply with the return address, so please wait for it rather than sending the parcel anywhere.

Use a tracked service. We cannot confirm a refund on a parcel we cannot prove arrived.

There is no direct swap for exchanges. An exchange is handled as a return plus a new order.

Once your return reaches us, inspection takes 3 to 5 business days. We will then let you know whether the refund is approved.

Approved refunds take a further 5 to 10 business days to process, depending on your payment provider, and go back to the original payment method.

Shipping costs paid at checkout are non-refundable, unless the return is due to our error.

Contact us within 48 hours of delivery. Send your order number, photos of both the product and the packaging, and a description of the problem.

Photograph the packaging before you dispose of it, because transit damage claims depend on it.

Where an item arrived damaged, is defective, or is the wrong product, we cover the return shipping.

File it through our claim page. Submit the form even if you are not sure whether the issue is covered. Filling it in properly is what speeds the process up, and our team will assess coverage from there.

Check your spam folder if you do not hear back.

Attaching the right evidence makes a real difference. Depending on the fault, useful items are: a pairing video recorded in a quiet room with the startup sound audible, a 30-second charging video showing the charger indicator, battery screen and DC-cable button in one frame, a clear photo of any error code, and the ride or mast logs pulled from the Waydoo app.
