If you want a specific reason for why your craft isnt working properly your going to have to indicate some more details, but for now some of these suggestions may work.

- Eliminate as much weight as possible from the craft. Remove anything that is not required for the hovercraft to function or to be safe
-Examine your skirt design and ensure that it forms a maximum seal so that all the air is concentrated on lifting the craft itself rather than escaping
-Find a prop that suits your engine. Maybe the hovercraft can not lift because your prop is either to small to provide enough lift, or the prop is too large for the engine to run it at its max rpm. Either way it may have an effect on performance

Thats all about I can say for now. If you need more information please provide me with details. Perhaps the type of hovercraft, whats its made out of, engine and prop size, ect

Hi, I am doing a project on how adding weight onto a hovercraft will affect its lift. When I started adding weight onto my homemade hovercraft, its lift actually rose with weights ranging from 10lbs-30lbs but pounds 40-100 lowered the lift. I don't know why it did this, please give me any feedback/information that you have on why it did this.

p.s.
The hovercraft I made was a small homemade one made out of plywood, a 6mil plastic sheet for the skirt, and a shopvac as an engine.
