good idea oyvind i'll show you my new fixed propellor soon
so probably it could be incorporated with your idea
i've got some questions
couldn't be better to use maclaren F1 panels?
how do you prevent tilting pannels in the oposite direction to air flow?

you know the duct gives the air right direction
and, which is very important, it gives "more" air
why quoted?
because if the duct (tunnel) is not heigh enough it didn't
you know when air is pressed under the hovercraft
it looks for escape
then when it escapes around the rotating blades
the rotor sucks it again
so the tunnel has to be heigh enough (by trials and errors :)))
it wouldn't be so importand if the machine could be stronger
but if it could be
it would be helicopter :)))

it is the best thing in your design

| Hello I've seen the marvelous creation of hovercrafts by Paul Kleniewski ( (URL) ) and that gave me some ideas. Here can you see a simpel construction of an propell that I made. I've not taken any photos yet, but here is one image made in Ldraw: (...) (21 years ago, 5-Feb-03, to lugnet.technic)
