New in town.

[user 11673]

Well this is my first post here.

After almost 20 year dealing with planes (last 5 with jets), I decided to give a shot with rc boats.

We have a good pond in our club Hobbyland. Locally none one is doing boating, I guess I'll be the first trying to intruduce boat racing here with the help of a couple of friends that are also into this.

This weekend we'll beging setting up the 1/4 mile oval course as per the IMPBA standar...too many rules! but very well organize.

I'm still have too many thing that I do not undertand about this game. Maybe will be good to see if in my next trip to Miami I can also locate a boat race to visit and learm...

Vision Craft 20 in the hull I'll choose.

Not sure to go for the OS or the engine sell by Hyperformance with a Rossi 3.5 Powerhead http://hyperprod.bizhosting.com/3_5_outboard_motor_1.html(Not sure if Rossi are as reliable as Novarossi)...is not easy to buy stuff if you are not familiar with the full options of products...and I don't like to buy 2 times.

So don't wait for me to ask and feel free for whatever recomendations you can make to me. Is more than welcome.

I just wanted to introduce myself. When the times come we can organize an international race so you guys can come and spend a few days down here.

Welcome, to IW. there is ALOT of great people on there with alot of answers.

The Vision is a great pick for a hull. I would start out with an OS and run the sport class. A stock motor is less picky,and the OS is a great motor.

A few things you might wanna include in your boat and a few tips to save you some money and headache

-Metal gear steering servos, I use the hitec 645, others can chime in on their favorites

-get a few spare props, if you have the tools and time to sharpen and balance your own, the grimracers are nice and are pretty close to balanced right out of the package, the octuras require a little more work before they need to be put on the water or there are a lot of people on this forum that are really good with props and can set you up with something specific for your boat

-a lot of .21 tunnel guys run o'donnell plugs, blues, OD9's or 89's, I have run all three and like the 89 best, but for cheap the blues are a good value

-the little engines live nitro. with planes you probably run 10 or 15 percent nitro fuel, with boats 40-60 is common, I dont know the fuel availability in the D.R., but grimracer 50 works real good.

good luck and post plenty of pics of your new boat

Thks Tim.

I'll look foward to meet you all.

The OS comes water cooled and air cooled... I notice all other brands use water...Does it worth to spend the extra bucks for the air cooled OS?

Is "picky" the only reason to go with stock engine? having the engine tune is not a problem.

Stuart,

On servos I have a few digital JR8611 that I used on jets...220oz torque and hight speed. I think they can handle the job. Ok with digital?

As for the props...2 or 3 blades? What do you mean with something specific for my boat?

It seems O'donnell discontinue their plug...? Anyway i guess the plug need to be hot like the OS A-8 right? Or the plugs are turbo type?

Regarding the fuel we locally have 30% nitro...Which % of oil? Synthetic or Castol? I'm open to import the fuel...

Thks for your welcome. Look forward to hear back from you.

Take care,

MS

 

[user 11673]

I like this engine...at least for the way looks. It is TOO picky?

BTW...If the boat flip over and the engine drinks water....do you call off the day?

1. digital is fine and 220oz more than enough torque. I know that servo well, I have seen a lot of them on buggies and they are tanks, should be no problem for your boat.

2. I do not run the vision craft so I am not sure what prop it likes, generally you find that a boat likes a specific prop. I carry mainly ocutras and the common octuras are 437/3, 440/3, m440, x440, 1440, x442 and in grimracer the main tunnel props are the 40/52/3 and the 40/52. With my OS engine on my VS1 I like the 1440 cupped, backcut, and with a little of the fat trimmed off. different props have different characteristics, which is a little confusing, I keep a book with all the info I get off here to keep it straight. If it were me, I would find someone on here that runs a vision craft and find out their setup.

3. as far as I know o'donnell is still making plugs, I think the owner posts on this forum, you can look him up and ask him if he has a dealer/distributor in your area. the plugs for the o.s. are not turbo plugs, as for the rossi I have no clue. generally speaking the plugs i listed above are cold plugs, if you run 30% you may wanna try a medium. Also, it has been my experience that OS plugs are the most expensive, shortest life plugs around. Stick to McCoy or O'Donnell if possible. Better plugs for less money.

4. Fuel wise, if you can get it Grimracer fuel is great. It was designed by an outboard guy and has been a great success. Price is fair and performance is good. I think Grimracer is distributed by hobbico so when your hobbyshop makes a fuel order, just have them get a case for you. I have also used o'donnell boat fuel in 50% and it worked really well. Find out where your local hobbyshop gets fuel from and start from there. I have heard that you do not want 100% synthetic in outboards, but I do not know if that is just a myth. I run either grimracer or odonnell and dont have a clue what is in them. Another general rule is that you want an oil content higher than 16%. The real low oil car stuff is supposed to be bad for them from what I have heard, I can neither confirm or deny that though. I just run what everybody else has already tested and determined to work.

5. If it were me, I would get the O.S. engine. They are virtually the same price as the rossimodel once you are all said and done, in unmodified form they will run virtually the same performance wise. Parts will be easier to find for the OS engine, and they are extremely reliable. Their lowers are the best lowers on the market and the powerheads are the consensus favorite for stock and some mod racers.

[user 11673]

It was much more that .02 cents.

I got your point about the right propeller. Let see if anyone with a vision Craft 20 can tell me his recipes for this...

I'll check for the plugs and for the fuel. Locally we have a friend importing Morgan Fuel...I guess I can order him a case or two.

OS water cooled or Air cooled?

What you guys do with the engine if the boat flip over putting the engine under water? call off the day?

 

[julianconde]

if the boat flips all you have to do is take the glow plug out and turn the engine over until it everything is cleared out of the engine.. and you can continue your day testing ok. Once you are done for the day make sure you disconnect the fuel line, take the glow plug out blow the engine until nothing comes out. flood the engine with WD 40 and due the same after that use corrosion X and do the same a few times. use marvel oil lubricant and do it one final time and you are ready to go home ok..

The OS air is a new engine. JD (a well known guy with a ton of experiense) has said the new air cooled is a bit faster. Thats up to you if you want to spend the extra $70. You cant go wrong with either type of OS. I misunderstood, you are not new to nitro engines. If tunning is no problem you could go with a mod moter like the one you pictuered. It looks OK, I wouldnt use that pipe go with a Irwin they are disgned for boats.

Props 2 or 3 blade, use whatever the boat likes. In my boats it seems like the 2 bladers may have a bit of speed on the 3, but are less stable. I use both. you just have to test to see what your hull,engine combo likes.

If you flip the boat over and water gets into it, just take the glow plug out turn the motor over for a bit (to get the water out) then give it plenty of fuel while turning the motor over, put the plug back in and your good to go!

At the end of the day you want to pickle the motor, take the plug out while turning the motor over spray with WD40 or Corrosion X (a rust prohibitor) then spay a light oil in while turning the motor over like after run or a light air tool oil. This is how I do it other guys may do it a little diferent.

One other thing you want to lube your flex shaft while running from time to time.

Julian, I was hopping to get that answer. Gracias

That's right Tim, not new into nitro engines...at the begining of this year I also started racing 1/8 buggies with hight perfomance racing engine like the Werk +40K rpms and my car mates will be racing the boats too now and they have much more experience than me. We enjoy been competitive...that's why IF "picky" is the only reason, I would rather go with non stock engines and deal with a proper throtle management while in the "driving miss daisy" stage.

I saw in another threads here that you guys are using brands like novarossi...In those cases which lower part are out there to complete the full set up? what is "TT Lower"?

And for Vision Craft I contacted him on Friday to order my hull...but still waiting...aparently is a "from the house" business...?

Well...I'm leaving to the pond now to begin setting up thing for the 1/4 mile oval course.

TT lower is a lower unit from the Thunder Tiger motor.

The Novarossi is a kick AZZ motor. My brother Mark Leyde "lights" is the maker of the outboard conversion kits for the motors (turns the inboard motor int an outboard). Im sure he will be making more conversion kits this winter, for $250.

Another motor you may want to go with is a TechnoPower no conversion kit needed, price is about $315 (depending on the ero), you will need a carb they do not come with one.

A Go motor ready to go will be avalible around the holidays for around $250

All the prices above are not incuding a lower unit, in my opinion I would use an OS lower. All motors I have listed above bolt right on the OS lower. If you use a Lawless you will need an adaptor plate.

OFF TO TEST!!!

Tim,

I find these pictures here:

http://www.facebook.com/pages/Tunnel-Hull-RC-Boat/118542198218487?sk=photos#!/pages/Tunnel-Hull-RC-Boat/118542198218487

Are you familiar with this set up?? One of the lower unit is clearly an OS...the other with carbon fiber I guess is a Law less...

 

[user 11673]

Regarding the race course...what is the criteria to choose between 1/4 or 1/3 miles course?

Is because of the size of the boat/engine/speed or is just becasue of the space available in the pond?

Which course you prefer to run?

 

[Blackout]

1/3 mile is prefered if it will fit on your pond.

The lower unit with the carbon fiber is a Techno prototype. I don't think they are available yet. The Techno engines are available for bolt-on to an O.S. lower. You will need an O.S. carb too.

 

[user 11673]

It could fit, but wheels will have to be add to the hulls in case they run out of the pond in the curves ...

Finally I got to the point to make a decition. I'll go with the combo of head unit Tecnopower and lower unit OS.

I'm willing to go with Vision Craf but they are taking too long to answer.

What additional boat stuff do I need to put my boat toguether? Seal boots, radio box tape, lube a/o grease, throtle cable??

Do you use pull pull cables om the rudder or pushrods?

Getting closer...

Thks,

MS
