Hi,(adsbygoogle = window.adsbygoogle || []).push({});

usually don't ask for help but this is bugging me now!

I am working on a r/c model hovercraft, i have been trying to work out the upthrust but can not get a formula to do so.

I know the air cushion pressure is a factor, i am using a ducted fan for upthrust with attatched 9 v motor.

Any help would be very much appreciated.

cheers
