Status: offline 		Phil, you were right, I was not dissapointed! Lots of interesting articles and plans including the Hydrofoil ( hydroplane it was called) I have been after for so long. Once again many thanks sir!

Now I must think through the design and see how (if at all) it could be adapted to R/C. Trying to get her to turn well might be tricky. I also wonder how the best way to implement some sort of trim once she has risen and is on her "wings" (foils) It really is an odd looking design. Reminds me of a wheelhouse of a tugboat. Outside of that one notable familiar part the rest is complete whimsey. I don't know if anything like it has ever been made. I guess that is what makes it unique!
I am not much of a boat man myself when it comes to modeling but I did run across another R/C boat called the Miss Take which really caught my eye. Uses both an air rudder and water rudder.

Status: offline 		morning. feel like that I'm all thru with the latest bug bout and ready to downsize my plan of the Channel Wing from 60" to 36". was just tooo big. will be sized for electric. finally have the electric power supplies for both the Ring Wing and the Hoop Skirt, now too learn how to use them. am still looking for additional models of Roy's, would like to build one of each of his designs-- all help is appreciated. dick

Roy has published over 150 articles, plan, and How-To’s since 1945. He also published a novel, and a book on steel guitars

He was inducted into the AMA Hall of Fame in 1999.

He was my friend and I will miss him.

His autobiography can be found at:

Thank You,

The above link? shows the principle of the automatic trimming method used by the Hook Hydrofin. Sorry about the web address, i cannot upload pics from my machine.

The early 50s were full of innovative models. I remember the Dorland Hall Model Exhibition of that period. There were Electric Ducted Fan aircraft flying, Pendulum Stabilised aircraft and even Magnet Steered no less. Then there was the Hook Hydrofin, it was demonstrated in a pool and subjected to waves. The forward float sensed the wave height and changed the angle of attack of the main foils and there you have it, Automatic Trimming!

Status: offline 		John, This will be a good help for me. It will help in forward stability no doubt. Steering will be more of a challenge if you look at the design. The thing is poised at running speed in a 3 point stance much like a Hydroplane boat. This means flat turns.

If I were to modify the 2 outer front foils to a single bowed foil connecting the 2 outriggers might that help with letting the hull roll some to allow a turn more like a boat or plane normally allows?

Would this even be desirable? Seems natural to me to do so.

Another thing that I think would need changing would be the Y or V configuration of the rear foils. I think a T would be most suitable for R/C use.

For "freeflight" or tether use the design that Mr Clough has for this ship in my mind is flawless. The only reason to make any changes in the design are purely of my own desire to increase the performance of the ship under different intended usage.
I wonder... How would Roy Clough Jr have done it?

Adam for anyone to have been able to call this man their friend... My hat is off to you! My condolences to you as well. A huge loss for all of us indeed.

The best thing I can do is to try and bring Mr. Clough's designs to life and make sure he gets credit for it wherever I can.

Robert

Hi Robert,

Ah, I see where you are coming from. I feel that a simple water rudder tacked on the upright part of the rear foil support would enable a normal (flat) turn. especially since the main lift foils have an effect similar to dihedral that ensures flat running and reduces roll. The bank into a turn of the displacement hull fast boats is caused by the rudder being below the waterline and the resultant turning thrust heels the boat into the turn. That made me think a bit when I first observed it on a fast Corvette turning hard and leaning into the bend like a motorbike. I found it very impressive watching hundreds of tons leaning into a bend. Please keep up with the building, I am enjoying building models vicariously.

Thanks for the "heads up" on the demise of Mr Clough, never met the man, like so many of the people I only read about. Now I will never meet him but he still lives on in the hearts and minds of modellers worldwide. I think it needs youth to recognise heroic figures, shame, at my age I am impressed by much of what I see but I no longer recognise a hero. The AMA archives of Biographies of famous modelling figures make intriguing reading.

It's great to see the models Dicknadine is producing.

I came across this thread not to long ago and noticed the Hoopskirt iti s absolutely beatiful

What a great vintage project i will give it a try and build my own brushless version with a diamter of about 20"

g-rock/Gene provided me with a copy of the hoopskirt Thanks!look like a fun and easy project to build.

Before i start i have a few questions to ask since you have built one already

How is the overall flying expirience with this particular annular wing?

What is your control surfaces setup? Do you have rudders and elevator or elevons controling the plane. The plans call for a elevons type of control for the FF

Another thing im a little confused. The airfoil is symetrical did you shimm positive the hoop in acordance to the horizontal fuse line to give it a slight attack angle.

And did you had to shimm the motor at all.

How do you launch this model? Do you simply hold on to the top fin rudder and throw it and land on one wheel later.

Im very curious to see how will it fly in real life very interesting design i was looking for something like this a long time.

Status: offline 		its 21" dia x 6" chord, covered with red mica film. 12 oz, no battaries. not flown yet, still waiting for my electric geru to show up and do the power instl. right now its covered with balsa sanding dust from the other new models under construction and or waiting for electric power instl also. my 1st one flew couple of flights pretty good, before Katrina took it along with all the rest of my models. the rudder and elevator servo's are back next to them, needed tail weight. made my wing form from heavey 1" cardbord, balsa strips were 1/16" thick, yellow glue. sand to shape after its cured. make sure that you sand it coreectly-- I did it wrong and had to make a 2nd one. sure will raise a lot of eyebrows. ask if you need help. dick

Status: offline 		Ok that makes sense one more thing. when the plans were enlarged how long did the boom lenth increased. Was there any simple calculation that was need to figure that out.


Forgot to ask something. Have you ever thought about making it a pusher configuration. That would save the prop and make it look cooler i think. Since there would be no prop in the fron there is a posibility for a foam nose block easy to add weight if needed to balance.

I think you missed a little of my previous question about the motor and hoop being shimmed at all

Status: offline 		changeing sizes is no problem, just do the same for all dim. never thought about a pusher, one way to find out is TRY it. I'm just about ready to put a small fuel moror on mine and get it flying. I have some 30 acres to fly in-- once all the horse corral fences gettaken down and everything bush hogged. right the cold weather and blues have slowed me down. more lare. dick
