Frequently asked questions

What is the difference between FoilBoost and a Flyer EVO eFoil?

They solve different problems.

FoilBoost is a foil-assist unit. It mounts under a foilboard you already own and gives you the power to get up on foil and extend your session. It is 5.6 kg, delivers 33 kg of thrust, and runs a 432 Wh battery.

The Flyer EVO is a complete electric hydrofoil: board, mast, wings, propulsion and battery as one system, ridden with a wireless remote.

Choose FoilBoost if you already foil and want assist power. Choose a Flyer EVO if you want a complete eFoil setup.

What are the FoilBoost specifications?
  • 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.

Where do I find my manual?

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.

My battery is swollen, hot or damaged. What should I do?

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.

Can you provide battery shipping or compliance documents?

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.
