I took my basic Hovercraft model and the parts from a broken RC toy and repurposed them to make a new toy. This hovercraft will be able to float above water.

Step 1: Lift Motor Batteries and Switch

I installed two 7 v RC Helicopter Batteries and hot glued them to the Lift Motor housing. I hooked them up in series to give me 14 volts. I added a single pole single throw switch to turn the lift motor on and off independent of the thrust motors.

Step 2: Installation of RC Electronics

I hot glued the circuit board and battery housing on the Lift Motor housing. I did not install a power switch for this component. It is easy to remove the battery.

Step 3: Thruster Setup

I hot glued the gear drive motors from the RC toy and attached them to a wood dow. I had to use my Dremel tool to grind down the gear till it fit snug in the propeller. I cut the dow in half to attach to the Lift Motor.

Step 4: Thruster Calibration

This part was a little more difficult. I had to solder the wires so that when I pressed the left control forward, it would turn motor in the direction of forward thrust. Next I had to do the same thing for the right thrust control. We now have wireless thrust control over hovercraft.
hi I'm starting a hovercraft group to share experience and designs to make the best hovercraft s possible I was wondering if you were interested

I added a small fin to help control the steering over water.

You'll probably find that it hovers better, with less power, if you follow real hovercraft technique of forming a cylindrical curtain of air, by putting a smaller plate underneath and having the air blown into the gap between the two.

True to that concept. This was the first one and I wanted something simple. The lift motor has I used has an air current flow corrector built into the housing. The thrust comes out straight without spiral turbulence. It came out of a decent hair dryer.

Pretty slick. If you look around on the Web at other hover craft, you will notice they have a flexible skirt on the bottom. mainly this helps with rough terrain. Also it helps transitioning different terrain. you could potentially use a plastic grocery bag and some tape. keep up the good work!

Thanks for sharing. I have a bicycle inner tube I may end up using. This is my first hovercraft project and I am just playing around. My next one will be a little bit more powerful. I have pulled out the components of a Shark cordless vacuum cleaner. I have tested the thrust and it is very powerful. I think I will use the bike tube for that project. Thanks for checking out my project.
