Hello, Im new into hovercrafts. Any reliable hovercraft to buy?

Hi, I fly small size electric rc helicopters but have been interested in hovercrafts. It is just that I see none in the market. Hovercrafts seem hard to find in any LHS.


May you tell me please what hovercraft is good to buy for a beginner? Any well known brand out there you recommend me?



First of all, I would like to know how is it that single main motor hovercrafts counteact torque reaction. In a single main rotor helicopter you have tail rotor for this. In a coaxial helicopter, both reactions cancel out. How do you work it in a hovercraft for counteract torque reaction?

About 7 years ago I attempted to build one, but it didn't work well

This a diagram of the wannabe hovercraft I build years ago. It was all made of balsa wood, except for the skirt that I made out of that kind of trasparent plastic you use to cover your books.

It lifted, not much, but it lifted a bit. I chose this configuration to avoid setting the motor shaft on a vertical position, then avoiding hovercraft starting to turn.

However, I didn't set correctly the center of gravity so when it lifted, it was not evenly lifted. In addition to that, torque reaction complicated everything.

The arrows show the direction in which I thought air should flow. The screen (that triangle in the middle of the hovercraft) was set at 30 to deflect the airflow coming out from the motor, trying to avoid major loses in power.

I just started it once. As results were disappointing, I did not try it again nor I tried to improve it. I took out the glow 0.049 motor out of it.

Thanks to you all!

If you want something goes on water then you can get the scamper, otherwise the axon racer.

model hovercraft

Good performing model hovercraft made of foam are easy to design and build. Do a search on the internet to see what others have done. If you have an RC set up already a really nice HC could be done for less than $30.
