Free flight '30 min.' PC fan hovercraft

I saw numerous videos of simple PC fan hovercrafts, but only a few used a skirt. PC fans are not the best choice for hovercrafts, but it made me more curious. So here is my version:

PC fan hovercraft ground clearance test (0 min 27 sec)


It's able to glide over 1-2 cm high obstacles.

Thanks!

I just finished my round the pole model. It's powered by 12V 10W cooling fan (140 CFM). Its skirt is "C" type in front and on the sides, "bag" type on the rear.

Round wall/cell skirt hovercraft model test:

The air gap in the front is smaller (~2 mm) than the rear air gap (~4mm), so the difference of the air spillage propels the model. Skirt is made of leatherette.

My first model was a radio shack brushed motor running off a 9 volt battery with a hand carved balsa propeller mounted in a piece of foam.

I just got the Hobby King Hoverjet and I'm a little disappointed. Not because it doesn't work well, just that it's terrain handling capabilities are just so limited. I like hovercraft because they can go from water to land and cover semi rough terrain. The Hoverjet was built for speed on perfectly flat ground.

My next one will have an extremely high skirt with a squirrel cage life fan and probably 2 low KV counter rotating propellers.

I think you should make a skirt for your Hoverjet. It's a great opportunity to experiment with different type of skirts. Only a few mm high skirt will dramatically increase its terrain handling capabilities, but you can make a really high skirt...
