FlyChair has been developed for disabled paragliding over 15 years by a company in Finland. https://www.flychair.fi/
The total weight is 12- 15kg and it uses attachments which connect it to a standard paragliding harness. The buggy can be self propelled on the ground like a standard wheelchair. All parts are aluminum and frame is anodized. Easy attachments and fast buckles and quick pins make it easy to dismantle and transport fitting into a small car boot.
It works with hill launches and with winch tows. It can be flown solo or tandem with a disabled passenger.
We have 2 Flychairs. One was kindly donated to us by the Guernsey Paragliding Club.
