U may not know it but Phil Thomas has used the inverted aero foil canard design on his boats a long time. I offered to buy you one for your birthday to build put YOUR motor in and run and you said you did not have the time. That cost 700 usd so I'm again equally surprised to see you here arguing with me about anything much less a SAW mono!. Tell me again what is your hand in my Saw runs or the Corvus? The only mono you ever showed me was a dumas skdadle so when did you become a 1m+ 20 kw SAW mono analyst. I'm a starter so what is your experience in this mono FE class?

I also didnt know you owned 1/8th scale boats So what ones do you own and how fast do they run?

Thanks in advance for you answer I know I have alot.

Currently I own a 16th and 12th a 13th LSH and 5 1/8ths scale hydros..They can all but 2 be setup to run at a moments notice.

Clugh

You should have had fabio send you plans for an 1/8th scale of his 7 liter so u can build it and bring it to Florida when i go check out Steve with my new boat to go after snook. They have a club and we can run there no problem . If you have something you have you'd like to show us we'd love to see anything superior to Ron Jones designs and the boats everyone runs here im sure!

Clugh

I can not find that Fabio had built turbine powered or even merlin powered unlimited so how he became a better unlimited hydroplane boat designer is beyond me.. may i have links to his unlimited work because all i see is diesel powerboats and the one hydro 7 liter boat.

Clugh

His monos are certainly illegal here like your friends

And old friend from just last week said this about these style boats.

Hi Hugh,
the Regi Fountain hull is absolutly okay . Do you know how much the boat waight with the ic motor ?

Possible you need bigger stringer or moore with the same high like the competition hull has with the ic motor as electric drive is haevier , waight moore. The stringer rise lift and reduce wettet aera to reduce drag. The stinger drife strut is okay on the photo has a step , i think, if allowed a rectangular strut give somthing like a trim tab ,that can be adujst the riding angle on the water. All other is set up at the lake and test drive divernet prop and stinger ( propshaft angle) , find the advanced set up. Mayby it is usefull to grind a flat triangle on the last 30 % of the hull . Like a riding plate that help lift and drag. On the other hand the deep V makes the hull run straight with less ruder deep and so less ruder drag .
Ruder is the biggest drag producer on surface driven boats .
I will show you later a boat that run in German f1 klass very suksecful. With a smaller version Hans Lehner won two word champion titel . But this boat run speed and stearing very tite. At full trottle the boat corners 180 degree in halve of the boat lengh.

Clugh

I wonder did he notice the Corvus has an insane rudder? And that the blade is significantly thinner than a typical boat this size . ?

Clugh

Also the flat from the cg back is not legal and is an FSRV thing. How does it work if all the boat is out of the water on a surface drive. . Alot of different theories blend together that do not make sense to me. John Finch had a rule of thumb that raised the drive from the keel based on its props distance from the transom. That seems to suggest reducing the lift generated and using the "v" for stability but maybe Im wrong.. It seems to me modern mono have lost strakes alll the way to the transom and that seem to be a type of semi displacement or a step in itself that actually reduces some of the lift at the transom for a stability trade off. When u add a tab 3mm from the bottom of the boat that creates and additional step.

Clugh

These are the synergy trim babs so I will take these dimensions to build the power tabs they are 2.5 wide by 1.75 deep.

Hi Christian,
Did you and Powercroco decide you don't want to participate here? I take it you have no interest in posting the motor data requested? You say the concavity is slight so what is the depth exactly? What other monos have you owned outside of the duman skdadle?? What is the fastest mono you ever had? I know you are both here reading but I didn't see any data or answers left.

Clugh

Did you know Reggie fountain started in Tunnels with Steve Seebold.? What a history. Like a prather lap cat III. How old is it? Its been about 25 years since it was produced hasn't it? What does it weight and what is the fastest its run with two scorpions on it. I know you've been saying how inadequate as a motor they are and that Powercroco was a "starter" or "Junior winder" but there is only a half % difference in eta between your engines.. . Their are several active American and European threads where you say the engines are no good. How did they end up on your tunnel and why not :Lehner's there?

I ran castle and Neu and a few others but never a scorpion in my boats. 1/8th scale guys here have known for quite awhile how hot they run. What many would do with the 4035 800kv is lower the cell count to 8 and run a larger prop at a lower rpm. Pretty good power but very far from the outlying marine engine.

Whats going on "EXP" you are from Germany you checking in on your boys? How are you? Do u care to introduce yourself? I see you have never posted anything here but have been on since 2004! Its 2023 so what brings you particularly to this thread today of all threads? Its really an airplane forum.

Those are vendor statistics youre not a Germasn vendor are you? If you are speak up. .

Clugh

How do those run on a prather lap cat II ?

Clugh

Ive been trying to separate the technical discussion from really advertisement! for quite awhile. The lies are killing us!

the two that have said no other companies have no how but the respective eta's are 93.5% and 93%.

Xnova, Cobra, Neumotors, and others have higher eta. Whats really good in Germany? Its hard to tell with them. If asked for specific motor data that they do not provide while telling Americans how great they are.

All my data is always openly posted.

What i asked for was a breakdown of total motor losses power density KT KM etc. and eta.

You should do your homework first before you start any defamations. Tyler saw the boat with concavity in the back in reallife.
The hull which set the final record 2021 had a straight back without concavity.
And no, i will not post pictures from the bottom as i will not defend any accusation out of nowhere. And for sure i will not feed digital design, do your own homework.
The hull is based on the rules of IMPBA, NAMBA and German SAW.
The Chine is positive angled. Potentially you have some sort of distortion or illusion in your view that the hull is a cathedral design.

And in the end i dont care if you trust it or not.
I suggest you start with with driving, instead of writing. And top at least the NAMBA record from 2014

Regards
Ralf

PS: this is my only statement here, do not try to start a discussion.

Clugh

he says he here to give tips so Ive asked about his experience with 90 mph monos that are over a meter long and have not gotten an answer. he says the boat isnt any good so I want to see what maybe it can adapt from one 35 years old. Certainly ia prather lap cat II is much more advanced than anything ive ever owned.

Clugh

I know it will be because the next question is what was the depth??

Youve never seen me drive and I wont you at any an IMBPA event LOL. what the measurement. I see neiter of you have posted that.!!! you here it should be simple. What a song in the cathedral.

That explains it tyler let it in. Ask him what did it measure????

I knew it !!!! and thats what I told you.

theres you answer guys with still no NUMBER or measurement!!! So yeah go back to Germany and fix it b4 any IMPBA SAW. And thats where youll find me coz I can see right now what they did was bs!

Take a photo with the straight edge across it if it is valid that quickly solves it!!!

Clugh

U wont! U bragging and your boats illegal! Prove it is not!

I see I brung you to me..

when wil;l you be making a IMPBA run so I can be present! We will find out about ya boat.

Clugh

NAMBA as of yet has pot contacted me back pertaining to my concerns but someone will have to eventually as I just applied to be a member. Im looking at the language now to see if a record can be disqualified after the fact.

You dont even know what the rule is i bet. .

Christian is the one that sent email photos of your boat so shouldn't you be mad at him???

What you mad about thats a guilty response youd just laugh with a photo of it then sayu i dont know what im talking about. Tyler said its okay is not the rule. If he didnt slap a straight edge across and measure it then he does not know, Now run get him and put together a number but a photo is worth 1000 words.
