Is there a boat in that rooster tail? Remember, the Stanley Steamer held a speed record for quite a while.

OK, I'm late.

But that was an exciting demo of steam at speed.

Well done, Paul.

This high speed hydroplane, hobby is all new to me....is the goal, just to go the fastest? These videos are the only time I ever saw these boats in action.

After the operator releases the boat...I guess the boat keeps going until it runs out of fuel? What happens if there is a failure? Is there any control over these boats once released?

I tune and often repair pianos. The wire used for piano "strings" is high quality, heat treated steel. The best "string material" used by piano builders used to come from Germany. However, this piano wire can rust, and pit, and is heat treated so that the wire stretches. This "stretch' allows the piano tuner to regulate the tension on the 233 strings of a piano, over the life of the piano, usually lasting decades. However strings in a piano are under constant, high tension, and any potential weak point on a string, whether it be a speck of rust, or a nick in the wire, can cause that wire to suddenly snap. When wire is brought up to working tension on a newly strung piano, the technician will place a heavy sheet of cardboard over the strings as protection in case a string pops. You don't want to be anywhere near a piece of wire spring-steel when it snaps, and whips around! Your eyes will not stop music wire.

I hope some kind of plastic covering/tubing is slipped over that tether wire. Just saying.

Default High Speed Steam Engine

On last leg of new cylinder head with valve seat all in one with head its all made out of en 24t.
Should solve valve insert leakage.
June will be the test, hopefully it wont be a flying steam engine with all the bits to repair.
A new hull has been made after 2013 crash.
Trying to keep the weight down but a new modification has added some extra weight.
Hopefully 135mph might be achieved but nothing can be taken for granted.
Competition could be interesting?
Development keeps the few brain cells working.

Update on new 2014 steam hydro hull and engine modifications after a bad day in June at Kingsbury Water Park this Sunday July 13th after a bit of tweaking to the launch system on my second attempt managed 102 mph.
A problem I had a few years ago i.e. the prop jumping reappeared with some helpful advice angles on the prop skeg and front canards was changed.
The third attempt was very promising with an average speed of 122.5 mph but still prop jumping.
A test run was allowed at the end of competition but the launch was a disaster.
A problem appeared the water pump requires investigation as at times it stopped pumping on trying to fire up amazing what an engineers favourite tool can do i.e. a small hammer.
A friend took a video of the disasters and good runs so will try to supply a link when available.

Here is the video Bobs and my flash steam hydroplanes at work the first meeting in June was not very good for both of us but things are getting better at this regatta.

I have to trim the hull and that is very critical to keep on the water or become an aircraft or submarine at the speeds now being achieved.

The new cylinder head is good and cam follower OK trim is the key to going faster now

Default Speed attempts.

Hi Paul,
Many thanks for the Vid of you and Bob's running attempts, it has given me some encouragement to have another go at my Flashsteamer OOYAH although I will not run it on a club day but on one of our working nights.

Last year I had an incident when something hit the rudder and knocked it off 30 deg unknown to me so it was a struggle to get it back under radio control.
Hopefully I will get it to run and somebody can get a Video of it to post, it's so encouraging to see that even you guys have off days.

George.

Are you still running cast iron pistons with Dykes rings?

We both have had plenty of off days it's now into the experimental for both of us.
My prop-shaft steady bearing has been running very hot probably needs more clearance?
A bit of woodwork the rear wing half of it broke off when launched on the 122.5 run.

Yes I have no problems with them running in a steel liner.
