Many thanks to "colin" for correted my translation.
These plans were designed for a race version of the hovercraft
For a pleasure version it is possible to fill the channel with buoyancy aids.
It is possible to add a seat with a higher handlebar
(Put the handlebar 30cm higher and add 10cm to the height of the central
channel)
The weight of the hovercraft is around 150kg
The Rotax 503 or 50CH with gearbox is the best choice. On this hull it
would be possible to mount a 100hp engine, but this would require some
hours of practice :-)
And it would be possible to mount a 20 HP engine (4 stroke)
Before you start anything, TRY TO CONTACT US, but in all cases do not start your hovercraft without a protective grid infront of the blades.
The blades will fly forwards when they break
Enjoy your hovercraft
