10th scale modern

[T.S.Davis]

so........ah? If one was going to build a 10th scale modern, what runs well?

We messed with some vintage a couple years ago and they don't all translate well to FE. I know the moderns will be the same way. A twin wing T Plus for instance isn't likely to have enough hp on a limited motor for the vents. UNless it only weighs a few ounces maybe.

Todd's Lobster runs pretty well but what a gob of work that took to figure out.

So who has tried what? Spill it please.

[JimClark]

Curious as to what you were disapointed in with the vintage boat's?

[T.S.Davis]

I should have said. Fred built a Notre Dam. It was the third we had done but the first at 1/10. I did the cowl for it. Came out pretty nice. Ran pretty good too. Took it to the nats and saw a discrepancy in between each of the boats. Some were really fast. Can't remember exactly which boats were which.

10th has never really been on my radar. My son was bugging me right after the nats about building one.

.....oh, for him of course. Him being my little hostage negotiator.

He gets all upset if his boat is slow. It's kind of comical to me. He yelled at me for making him hit a buoy at the 09 nats.

http://westcoastcustomboats.com/ - Craig Bradshaw make a great hull. That is what I have run.

[JimClark]

you can easily be doing 50 on a modern boat with a spec setup. The vintage boats I think the Karelsen designed hulls are the best for performance (of the vintage hulls) which is probably what the Notre Dame was especially if it was built with Gary F plans. Same hull design as my Bardahl.

[Darin Jordan]

Terry ,
Brian makes a MEAN 82u55 hull....

[JimClark]

I know Craig and he make very good hulls in carbon fiber. That said I would go with one of Mike's laser cut kits as I like to build them. i like making sawdust and I am toying with the idea of building another 1/10th and getting back into racing next year

[T.S.Davis]

I like the turbine boats. I like making saw dust too. I'll have to stew on it some.

Are there any plans to update the motor spec? I don't think you can buy those old blue AQ motors anymore.

[JimClark]

Sure seems like it would be talked about

did you get a boat..or plans terry??

[leonard feeback]

Tower Hobbies has the aqua 7000 blue motor.

[T.S.Davis]

Tower Hobbies has the aqua 7000 blue motor.

Yeah, Ray pointed that out to me too. I actually found one in my box of prehistoric stuff. Hasn't been in a boat since 2009.

Ray, I bought a frame kit from ML for the 8255. Plan is to teach my 15yo son to actually build a boat instead of just pulling the trigger. Hopefully he wont glue himself.......to..........himself like his old man.

[Todd Fleury]

I would actually pay to watch one of you two glue yourself to yourself.

[Scott M]

Tower Hobbies has the aqua 7000 blue motor.

How does the aqua blue compare to the proboat motor 1500, is it legal for racing in the namba class, and what's the difference between the two? Thanks!!!

[ron1950]

ive had no problem getting my vintage to run well even with small props (45mm)....I know what u are talking about with the turban modern hull though .... next time out even though underpowered ill get it right....http://youtu.be/7BAfymCvji4

whenever I click on this, my virus scanner blocks it??

[Todd Fleury]

I believe we now have a full class of 1/10 scale modern in our club?

[T.S.Davis]

I think Toms is a vintage and so is John's

[Doby]

Guess I'll have to look elsewhere as the site seems to be unsafe....who else makes 10th's?

[rayzerdesigns]

it is legal in namba..the newer version of the proboat(dynamite) motor seems to be a little better,,but they aren't produced anymore..but can still be found..also the himax motor is pretty good

[rayzerdesigns]

I don't see why it comes up like that..its a completely safe site..and great boats..though he has a pretty big waiting list right now..

[rayzerdesigns]

we have a club race this sunday..I will get some video..

[JimClark]

I know Craig personally for a few years now and the site is just fine. What antivirus are you using?

[Doby]

[bozo586]

I think Toms is a vintage and so is John's

ron squires boat is vintage too! talked to his daughter at larry's h/s ----he'll be back racing 2015.:rockon2:

[T.S.Davis]

Maybe if we run some scales Ron will quit threatening us and actually come race.

[bozo586]

i guess ron put his foot down and told the whole family he's going to race again. we will see when he shows up at the next meeting,i hope it's true.

[rightturnonly]

Scales...now that would be worth flying up for a race....I'm getting to old for this driving 13 hours north...glad to see this getting some interest in the Detroit area..

[T.S.Davis]

Craig is pretty buried right now. What are ya thinking John? Craig makes a short list and the are NOT cheap. They're sweet but not cheap. The 8255 I'm doing also makes the Executive like your 1:8.

[tjcast]

So do these hulls have to be 'registered' with some one so there aren't 5 of the same boat running in a heat at the same time?

[Doby]

Rulebook anywhere???

[T.S.Davis]

Nope. That's only IMPBA 1:8 scale. I don't think they do 1:10 in IMPBA. I doubt we'll ever get enough to worry about it.

We will have multiple years of the Oberto though.

Let's see if they show up first.

[bozo586]

yes tom--some clubs on the west coast do just that and you must register each season if i'm not mistaken. someone please correct this if i'm wrong!

[Doby]

So, IF there is no formal "Rule Book" could I build a 1/10th hull and paint it as I see fit (keeping it in the "spirit") of the real hydros?

[JimClark]

Depending on the club you have to run a minimum number of races to hold your boat registration. I think you can pay a fine to keep your boat registered if you can't make the 4 os races.

not in NAMBA.

[T.S.Davis]

Not to sound too pessimistic but we've been threatening to run scales since they hit the rule book. We've yet to see 3 show up. Let's get them in the water and see if we can turn some laps. I don't care if there are 6 budweiser hull.

[Doby]

not in NAMBA.

So there is a set of 1/10th rules in NAMBA.............

[rightturnonly]

So there is a set of 1/10th rules in NAMBA.............

Yes, they have some differences between Modern and Vintage(turn fin for example). There's a section in the NAMBA rule book on 1/10th scales..

[Doby]

OK...now we are getting somewhere...

[ron1950]

We started running 10th scale a few years ago in sw fla and the spring shoot out by the wave blasters. Got about 6 boats now and are a blast to drive after u get them set up


Each club can put there own motor rules for each class we use the 1500 for both classes but thinking about 1800 for moderns

[properchopper]

Some 1/10 Scale NAMBA boats are built so accurately to scale that you can actually hear the driver fart : (listen at 0:37)

https://www.youtube.com/watch?v=SLOD_9vx8HI

[ron1950]

Good one tony. My driver is too afraid of drowning to fart

[ezhitz]

Is that why my driver has that silly grin.LOL

That reminds me......if any of you locals are following this thread, how about some scorpion motors?

That reminds me......if any of you locals are following this thread, how about some scorpion motors?

Geeze Terry, Do your finger tips hurt yet.... You have a long winter ahead.... :hug1:

at the club level your making this WAY TO difficult. Pick some motors and run the class. Commonsense prevails in this stuff, do what's smart.

Later,
Ball

[T.S.Davis]

By locals I meant the club guys. Should I just pick the motor or should I ask the guys that want to run it?

[bozo586]

i'm not building any more boats for the coming season-i'm doing five now and that's way to many.can't see doing another unless it's petes design!:bash:

[T.C.]

It looks like ya need to read the rule book before ya build one of these boats ?
This is not all of the rules, so please read the rest. http://www.namba.com/content/library/rules/namba_rulebook.pdf
Hope this helps ?

7. ELECTRIC 1/10 SCALE UNLIMITED HYDROPLANE
a) General Rules
i) The intent of this class is to replicate the look and competition of real unlimited hydroplane racing. Boats are 1/10-scale replicas (one inch
equals 10 inches) of the real boats that have raced on the unlimited
circuit. This class shall emphasize scale accuracy.
ii) Electric 1/10 Scale Unlimited Hydroplane rules will follow the Scal Unlimited Hydroplane rules (see Section 21) with the exception of the
following.


iii) Electric 1/10 Scale Unlimited Hydroplane rules are intended as a supplement to the Electric General and Sport Hydro rules. In the case
of a conflict with the Scale Unlimited Hydroplane rules (see Section
21) the Electric rules will prevail.

I copied this fron section 21..........

C. HULL SPECIFICATIONS
1. All boats will be models of past or present Unlimited Hydroplanes that are listed on
the Scale Unlimited Hydroplane Master Hull Roster.
2. Boats are to be built on a scale of 1½ inches equals 1 foot of the actual boat (1/8th
Scale).
3. The true scale dimensions of any Scale Unlimited Hydroplane will be derived from
the unlimited dimensions listed on the Scale Unlimited Hydroplane Master Hull
Roster. Boats will measure within the following tolerances of the true scale size,
excluding appendages.
a. Overall Length ……………………………... ± 1 inch
b. Beam…………………………………….……± 10%
c. Maximum Depth……………………………...± 10%
d. Afterplane Length (three point design)….……± 10%
e. Tunnel Width…………………………………± 10%
4. Boats will be painted, configured, and detailed like the actual unlimited as it ran on
the water. The acquisition of documentation validating a paint scheme, cowling
configuration, engine configuration, or other scale details will be the responsibility of
the boat’s owner. Photographs of the boat are an acceptable form of documentation.
5. Boats will enter competition complete with cowlings(s) and driver(s). If any of the
removable parts fall off the boat during competition, except as a result of a collision,
that boat will be awarded no higher than sixth place points in that round upon
completion of the heat. This penalization only affects the points that are awarded and
not the finishing placement of the boat which incurred the infraction. The placement
of and points awarded to other boats in the heat are not affected by this ruling.

I noticed they make some 1/10ths as well.......

Not sure if they would be legal..

[JimClark]

The few that I have seen would not be legal. One round nose wasn't even close it was 2 to 3 inches short

I'm hosed. I have a big project for Delta Air that will take me to Atlanta for 2 to 4 weeks. I leave this Sunday. So zero time to work on anything. Plus, my wife will be less than thrilled if I get right on a plan at the end of that adventure to go racing. ugh Gotta make hay and the sun and what ever that old saying is.

Tom is working feverishly on a scale though. Saw the progress last night. He should be ready for you guys.

[Shooter]

At least you will be able to see that yellow glowing thing in the sky when you are down there! I think I remember what it looks like.

[ray schrauwen]

I'm really stupid here so bear with me... If I have a scale hydroplane hull that is 30.31" long x 14-3/4" Wide is there any modern scale hydroplane that this would be close to scaled up 10 feet per inch? How would I find out?

[JimClark]

Ray here is the ERCU Master hull list

http://e-rcu.com/resources/forms-documents/

[ray schrauwen]

Thanks Jim, I'll bookmark it this time.

[T.S.Davis]

If you know approximately what your hull resembles that's where you start. Then you check dims against the scale roster. The roster is here (http://www.namba.com/content/default.asp). It's on the scale pull down at the top of the page.

Typically guys go the other way and start with the roster and build accordingly. More often than not you find a hull you like and build it from Newton plans or have a frame set laser cut by someone that has already done the hard work like ML has. Getting from Newton plans to a working frame set is a bugger. Used to be at least. The plans were hand drawn and are more ideas than exact. You had to have a little imagination to make it work. Not a criticism. Some of the plans are ancient. I haven't tried it from scratch Newton plans in a while. They may be a cleaner gig these days.

[ray schrauwen]

This TFL hull looks very close to fitting the U-1 Miss Elam Plus 08' . I just don't know the sponson depth. Of course there would be a fair bit of changes I'd make to it but, to try and stay on a budget....

I asked for a bottom shot but, I have not got one from HOR. I'd have to talk to Monica if I wanted one or Tom C. maybe...

What do you think Jim?

What do you think Jim?

"Scale" models are a WHOLE different ball game. The spirit of scale model boats requires a different mindset and commitment than you typical model boat. This document should have the original hull dimensions that need to be maintained... (you will need to calculate for 1/10 scale)

ML has some good stuff and links to other parts to finish. HE really has done a lot of the pita stuff to pick a 1/10th scale. Very cool.

Thanks Mike.

We're all over the place but it's my thread so screw em'. Is there any racing going on down there in January? Tom threatened to run down there on the weekend if there was. It's only a 10 hour drive.

Not sure I'll have much time. There are 4 of us going and we're expecting to work 7 days a week.

[rayzerdesigns]

Yes sir. I don't think he'll mind me responding for him. I think Bob Zola from Mojo Racing is trying to make it too.

Kill'n me to miss this. Great racing, great people, perfect weather, not frozen like a Popsicle. Gonna miss that Italian restaurant down town too. Great food, owner meets you at the door, good company, great times.........shuttle to and from the hotel too. Some people need that. Just say'n. Sure had fun despite my technical woes.

[Todd Fleury]

Terry,
Just remember there are still 3 motor options for 1/10 scale. Proboat (if you can find any), Himax and Aquacraft 1700.

[T.S.Davis]

Yes sir. I have two of the three. Isn't the Himax basically the same as the Proboat 1500?

[Todd Fleury]

From what I understand, yes.

[Doug Smock]

Did you guys say the old SV27 blue can is an approved motor? I have one of those. Thinking of selling my GP335 kit and getting a ML 1/10 scale instead.

[tjcast]

Ray,this doesn't look like a TFL hull. It doesn't show up on any of the lists that I have ever gotten from TFL

On another note, working on this trying to get it done for the WW.

Ray yes they are but they run hot so you can't push them like you can the other motors.
Burned mine up one season running a slightly cupped 447.

[Todd Fleury]

It all depends on the weight of your 1/10th scale. I have no issues running a 1700kv

[monojeff]

I don't know anyone out here in the PNW running the SV motors anymore.
If yours is holding up for you that's great.
My boat is right about 6lbs and was running around 47mph until motor died.
Motor temps were always on the warm/hot side.

Proboat and himax motors hardly break a sweat 447 props and can handle 3 blades no problem.

[Todd Fleury]

I run a winston eagle lobster boat. Ready to run weight of 4lbs.

[ray schrauwen]

Nice info, thanks!

[Coug90]

I ran on SV 27 motor in a pretty heavy Vacationville.com 1:10 scale to a CT championship back in 2002. The boat weighed in excess of 7 pounds ready to run, but it had a lot of angle of attack on the sponsons and handled like a dream, so you didn't have to get on and off throttle a whole lot during a race. It was water cooled and the engine well area was open to the elements with no plate sealing up the dummy turbo allison, so lots of air got to it too. I think the sponson angle and setup fooled the boat into thinking it was lighter than it was. I ran it with an Octura 447 and it was a lot of fun. H1 driver Jon Zimmerman built the boat four years or so before that out of carbon fiber and never had a chance to finish it after his hydro racing career started taking flight, so I made a deal to finish the boat for him, race it or a season and then turn it over to him again when I was done. He still has it, but has changed the motor, setup and tinkered with it a few times since then. He doesn't get out to race it much any more, but he's not going to drive the real boats forever and he has a young son. Hopefully we'll see it out again some day.

Hey Ray. What temps are you getting with your 90c batts and the Dynamite motor with 50mm 3 blade? I have been running 50mm 2 blade with about 120 degrees. My 3 blade hops too much right now to run 6 laps.

[rayzerdesigns]

6 laps with a mill right around 120..which is funny because with a 447 was running about same...

[monojeff]

What size course are you guys running?

[rayzerdesigns]

that was in Tucson..so not sure but its a pretty big course..as for Scottsdale..much smaller..so not sure

[rayzerdesigns]

will be heading to Tucson sunday..I think couple scale guys going..will try and get video

[ron1950]

any vid action from sunday ray? need something to watch here

[rayzerdesigns]

I had afriend video one race..waiting for him to email it to me

[macace123]

i need helpi am getting a bradshaw boat and a list of things to finish strut rudder shaft motor mount. can you send me a list of what your running RAYZERDESIGNS i need to get it to him quick like it will be for p-spec.

[rayzerdesigns]

speedmaster short hydro strut, speedmaster mini rudder, etti 540 mount, and depending on what motor you run, an 47 to 50mm prop right turn, and a right turn flex shaft

Lets see some pics of the skid fin :thumbup1:

[ron1950]

from what I read in the namba rules it can be any uncurved turn fin although it also says u should try to be as close to the real boat as possible as usual a big gray area I use a med speedmaster mono trn fin...looks like real boat fin and seems to work well enough...hey west coast guys....show us what u are using for turn fin on your moderns please

[monojeff]

Yep Ron you have it correct.
Always like to see what others are running.
Perticulary since he said be liked new turn fin meaning the old one was not as good.
I am also trying new fins this season on my modern boat.
I'll post some pics when have it finished.

[rayzerdesigns]

I'm not sure if I have pics..I had been using the fin that Craig sends with his hulls..it's a tiny bit different in shape..can't give away all my secrets;)

come on ray there are no secrets in 10th scale
