Start by laying out the basic shape with a marking pen and screwing 3/4" stock to the line. You can adjust by putting small shims under the motor mounts if needed. Check for at least 1/8" clearance all around. The motor should be bolted down securely.

Now is a good time to trial fit the prop and hub to the motor to make sure it runs true inside the duct.
By now the foam is hard so you can cut the bottom of the duct with a sabre saw to conform with the openings in the hull for lift air. It's a good idea to paint a white band at the tips for safety's sake. Once it is balanced give it a couple coats of paint to preserve it. Most props are pretty close when they arrive so it is not an undaunted task. Hang the prop on a rod held in a vise to see which blade is heavier than the other. Once you get it smooth you MUST balance it to avoid vibration. Once you have the tip clearance set you can begin to sand the blades with a power sander and finish by hand. Be very careful when removing tip material, it's easy to cutoff but hard to put back. A duct is most efficient when the prop fits closely inside the duct. You can save a lot of money by finishing your prop your self.įirst slide the prop onto the crank without the hub to see if it fits inside the duct without binding. You can buy the prop two ways, either finished or unfinished. It would be a great Father and Son project. The skirt is the heart of this thing and we didn't want to save penny's on something this critical. Although it busted our $500 budget we decided to purchase their materials kit which included all the epoxy,fiberglass, screws, and glue. The only parts we needed to buy from Universal Hovercraft were the Plans, propeller, propeller hub, and the skirt material. Most of the materials could be found at the local builders supply. This one directs approximately 1/3 of the thrust air to provide both lift and inflating the skirt. Most hovercraft use a separate motor for lift and thrust. We liked it because it only uses one motor. We bought the plans for their UH10F craft. We had an old 10 HP Briggs horizontal shaft electric start engine from an old riding mower that looked like it would fit the bill. Knowing absolutely nothing about hovercraft we researched the web on the subject and found the Universal Hovercraft website to be the best source.

We decided on a hovercraft after watching a TV special. I was looking for a project that my Grandson and I could build.
