There are fans that size out there (e.g. for ventilation, car heaters, hair dryers etc), but they don't tend to be particularly lightweight I'm afraid, otherwise we'd all be using them! Actually relatively easy to make a balsa straight bladed one, and at model scale, efficiency isn't that big a deal.

Today I spent a happy hour in a car wrecking yard pulling car heaters apart and despite the variation in makes and model they all had almost identical, surprisingly large, centrifigal push fans about 200mm diam - great for moving a lot of air provided there is no back pressure - not quite what I want.

Making progress. I have found that cordless vacuums (3.5v - 12v all have the same rather nice super lightweight (10g?) but small centrifugal fans (68mm diameter). I will attach a picture. The white is the small vacuum fan and the black fan is from a small toy hover craft that I will try the new fan on. The difference is that the new fan actually compresses the air as the air speeds up. The black fan speeds up the air but without compressing it it is not going to have much pressure.
The second photo shows a fan from a small 240v vacuum cleaner and this does look promising: 11.5cm in diameter and still lightweight - about 25g. I would like to try fitting one of these in a Taiyo first and see what happens. The vacuum was $4 from a recycle centre so a lot cheaper than converting to brushless motors.

Well that didn't make much difference. I started by fitting the smaller fan into a small (relatively heavy) toy hovercraft that presumably needs relatively high plenum pressure. The fan fits in beautifully with only a slight increase needed in the size of the air intake hole on the hovercraft. I was hoping that when the battery is no longer at a full charge the extra efficiency of the new centrifugal fan would still keep the hovercraft boyant. The fan lifts the hovercraft ok but it still needs full charge to move (weak thrust sytem as well? (Toys!)).

Ah I was going to post saying a found a fan you guys may like, I have my Dyson Dc02 vacuum open for repair the other night and it had a tasty looking fan in there, of course now I'm in the thread I can see it's almost identical to the aluminium fan two posts up.

Taiyo Edge RC & Team Edge RC same company


Taiyo Edge RC & Team Edge RC first off are the same company one was a dist for the rc and the other produced or I think the rc. I know this is a OLD THREAD but I came across it while searching around the forums here. Love this site. Not sure if any of you know but Team Edge RC made these. I don't think teamedgerc.com makes these Hovers anymore. They only build RC go karts. They also hold races for the rc karts both stock and modified. Wanted to post this as I don't think many know that Taiyo Edge RC and Team Edge RC are both the same. Keep in mind what I know there are many Taiyo RC companies out there in China and Hong Kong but not Taiyo Edge RC or Team Edge RC to my knoweldge. Hope this helps you guys out. Who knows they may still have parts?

i own 1 hovercraft. i used 1350mah 3s 20c lipo. what i did was put a 2 pcs 1n5400 diode so i dropped the voltage to 11.1v. i also pu 2s lipo on the rx. it performs so very well on grass since i paly it in our own flying field

Sorry to bump an old thread (although depending on which forum you use you either get told off for bumping or making a new topic when one already exists!)

I just wanted to ask if it's normal for these to have two long bits of polystyrene inside down the sides of the skirt kind of unattached to anything?

I recall mine had those. I think they are to provide emergency flotation over water if the lift fan stops working.

+1. Also maintains some cushion shape when shut-off....makes it easier to re-inflate.

OK I thought so but just wanted to check someone hadn't made a DIY modification to the one I got lol! It seems a bit weird with it not being fixed in place but of course when the skirt is inflated it makes no difference. Thanks guys!
