Haydn. I suggest a jolly good few hours surfing, as I had trouble finding small (4-5") propellers when building the Sunderland. 5 or even 6 Inches is jolly small for the aircraft world, and more than likely you will need an spinner adaptor to fit this sort of propeller on to a speed 400 motor 2.3mm shaft. I am contemplating an SRN 4 hovercraft and will need a similar sized 4 blade prop, but I think I may need a bit of luck for that. Cornwall model boats is reasonably cheap in regards the other stuff, but when you include postage on single items I would imagine the shop that can supply your propeller will be able to supply the other items as well.

Hi Haydn,

Before the Gylnn Guest Skimmer I decided to make an Air Boat using up the workings of a plane that I could not fly,and the end result can be seen on my Gallery.The motor is behind the prop as in a plane.the gaurd is wire mesh,
