Well yesterday was amazing! Got up at 5:00 after a sleepless night and headed off down the motorway...



Did a good hour of hovering around on the mudflats and beach and nothing to serious broke...



It is such an incredible feeling to be flying along over water in something you have built http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif



The 13 months in the garage and several thousand pounds were well worth the 30 mins of fun!



(would be nice to go out again so I can concentrate more on the scenery rather than focusing on the engine instruments and concntrating super hard on what I was doing)



Here are some photos and a video will follow shortly..



Many thanks for all those who have helped me over the last year http://hovercraft.org.uk/images/icons/smiley_icons/icon_smile.gif



Now all I need to do is work out how to get the damn thing to run a bit cooler....

OK, since I recently got some good advice on an engine over heating problem of my own - a few questions to consider: What ratio of water to antifreeze are you running? The more water and the less antifreeze, the cooler it will run. Is the coolant system completely full? You may have air trapped in there somewhere. Make sure your radiator fill cap is the highest point in the system. Run engine until thermostat opens and look in radiator to make sure coolant is full and flowing freely. All this assuming no external leaks etc. Good luck

Hi

I was just looking at your web site, the stainless mesh on your engine cover may not be letting enough air flow through to your radiator.

Also make sure your oil sump does not overheat if there is no air flow under the engine

keep it cool!

Ethylene Glycol is an organic liquid called anti-freeze which is added to water to make an aqueous solution of Ethylene Glycol and water. This is to prevent water in the radiator of the vehicle from boiling over. It elevates the boiling point of water. At the same time, anti-freeze will depress the freezing point of that same water to prevent freeze up in the winter, hence the name of the solution, "anti-freeze". This ability for a solute to elevate the boiling point and depress the freezing point of the solvent is the focus of this page.

Funny feeling is'nt it, I have had been going out for some time now with 99% reliability, I say 99 because just last weekend the rudder morse cable attachment came loose and besides having to use body weight to turn it was not a major thing, infact made the day quite interesting, anyway, back to the point.



Wven though I have been out quight a lot and given rides, by the way that is also something to get used to, everyone wants to go for a spin and everyone always knows better than you, shange this and fix that and the revs are too high and the fan pitch is wrong and, and, and, and just shut up!!!!!! http://hovercraft.org.uk/images/icons/smiley_icons/icon_lol.gif



OK back to the point. Even though the craft has given no trouble for months and months and you have checked everything every time you go out,



You still end up taking all the tools that you might and might not need to fix something with, WITH, EVERY TIME YOU GO ANYWHERE.



For some reason there is always a sence of unsertanty in ones own creation. And every time I go out I seem to have the cell phone and a packet of cableties in my pocket.



Any way.. Glad to see that things look sorted and may you have great fun. http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif http://hovercraft.org.uk/images/icons/smiley_icons/icon_biggrin.gif

Hey Don,

The things you say are true, but ... Straight water is the best coolant. Many racing engines run straight water. The pressure in the system raises the boiling point of the water so it doesn't boil over. Obviously you need some anti freeze for lubrication of seals and especially for winter use. My point was if his mix was too rich on ethylene glycol and not enough water then his engine would be running hotter.

If anyone wants to see the video of the first flight.
