hello ,
    my idea is about the hovercraft .
     help me in the construction  and what type of motors can i use
    my hovercraft which is 75&40cm in length and width respectively

There are a few hovercraft builds on the forum that you can use to get an idea of what you need to do.

Before you post in a thread, make sure it's relevant to what you're posting. I've split your post from a totally unrelated thread.

i need a help to design a hovercraft,any one please send me design with dinesions.

Now why is this topic sticky?
We need some good posts like the ones in the electric planes sections that are sticky...
