Super Hawaii help

[Hi8iS]

Hello all. I have never built a boat before but I have 2 Super Hawaii hulls that I would like to do something with. I want to reinforce the inside & replace all the hardware but don't even know where to begin. I am looking for recomendations. I do not want to use the SV27 stuff. I don't like blue. I am trying to do this as cheap as possible. I found this hardware on Ebay & was wonderring if it would work?

I'm also looking for a budget motor & esc. Definately want to go brushless. How about this?

[Hi8iS]

Anyone have any input on this? I was hopeing someone here could help me out with this? I have been looking here on OSE at the fiego motors. Which one would be a good recomendation for this hull?

Give us a bit more info. What are you looking for speed wise. Do you already have batteries or are you getting them special for this build? Do you already have SV hrdwr? If so, oven cleaner will take the blue off. You can also get things re-anodized different colors if you wish.

Also, I know the boat, but refresh me on the length.

[Hi8iS]

Here's some more info. I would be happy of this boat weant 40. I will be purchasing batteries for this build. I do not have SV Hardware, I just didn't like the idea of it being blue. But like you mentioned i guess I can change that so I would not mind using the sv27 hardware. The boat is 36" long with a 9" beam. Thanks in advance for any help.

[tiqueman]

Ive got a few boats set up w/ a Feigao 8XL or 9XL, on 4S Lipo and a 150A esc. the 8xl runs mid 40s in a 32" cat, the 9xl just over 40 in the same 32" cat. Expense wise, Turnigy batts from Hobby City.com are awesome. Get a minimum of a 20C battery. I run 2- 2S 5000mah 30C's in a lot of my set ups. Also you can pick up the Turnigy 180A marine esc for about half the price (before shipping) of something like an Etti 150A. I run both and actually prefer the smoothness of the less expensive Turnigy 180. Whatever motor you use, Id stay around the size of a 540 XL.. which is roughly 36mm wide and about 75mm long. Hobbycity has a 9XL I think, but Ive been quite happy w/ all of my Feigao motors.

EDIT: the motor you have a link to is close, but not quite. Id find a little longer one. 50mm my be a bit under power for what your wanting.

[Hi8iS]

Thanks alot. I will definitely look into the stuff @ Hobby City. How about the hardware I have linked to? If not is there some hardware that you would recomend? IS it better to go with soemthing with an adjustable stinger? I really like the looks of this hardware. But it says it's for a hydro. Just wonderring if it would work? Here's a link

http://cgi.ebay.com/aluminum-rudder-and-strut-system-w-3-16-cable-setup-/280422510002?cmd=ViewItem&pt=Radio_Control_Parts_Accessories&hash=item414a7bedb2

Also what size cable is recomended for this application. 1/8" or 3/16". Also do I need turn fins?

[tiqueman]

That is great hrdwr but wont quite set up right for your build. The reason being, the strut is made to tuck under the hull, whereas in your build, you will want to run a surface drive. Keep that supplier on ebay for your records though. Hes got some great product at great prices.

As for shaft sizes, you want your drive shaft to be 3/16, and you can run a .150 flex cable. (all avail in the store of OSE.) http://www.offshoreelectrics.com/pro...oct-oc150L-24c

Also on OSE you can find drive hrdwr that will work for you. Strut vs stinger has a lot to do w/ personal preference. Struts will give you more vertical adjustment, but stingers work very well on v hulls and is what a lot of manufacturers instal on the RTR boats. Also, consider what type running you will be doing. Casual sport boating or do you want to race? Some race boats ie, the SV27, come w. only one turn fin and an offset rudder and turn incredibly well right, but not so well left until you add another turn fin. And even then, lefts are not as good as right. If you want equally as well both directions, consider an inline rudder system, similar to what you had linked to ebay. I believe that ebay seller has a strut system for a v hull. The problem w/ a lot of his drive hardware, is its set up for 4mm shafts. Do yourself a favor and keep it 3/16 w/ .150 flex. I will say however, if you find one you just have to have and its set up for 4mm, its very easy to adapt it to hold a 3/16 strut bushing. Ive done that to 2 different drives from him. Just get it as an empty strut or stinger (without the flex cable etc.)

I think I covered all your questions... chew on that a bit and Im sure youll have more. Its a constant learning curve w/ these things. And super addictive, so watch out.

Some examples, you could run this strut (the mono style) http://www.offshoreelectrics.com/pro...d=ros-21-strut

with this rudder http://www.offshoreelectrics.com/pro...prod=ose-80050 or this one (mono set back) http://www.offshoreelectrics.com/pro...=ros-21-rudder

You could run a stinger, which is how I prefer it... (for 3/16 prop shaft) http://www.offshoreelectrics.com/pro...os-stinger-str


Heres the ESC I was refering to http://hobbycity.com/hobbyking/store...hless_Boat_ESC.

And a 9XL motor http://hobbycity.com/hobbyking/store...idProduct=6678

[Hi8iS]

Definately alot to chew on, but extremely helpfull. I think i will just use the stinger set up available here on OSE. As well as the rudder & cable. Do I even need trim tabs?

[tiqueman]

Do I even need trim tabs?

Id say you will need them to help eliminate torque roll.

[Hi8iS]

Ok The Hardware will be the 1st thing i will be buying. How about these trim tabs. They look a little bit more scale. Would they work?

http://www.offshoreelectrics.com/pro...prod=aero-7000

Also how about this flex cable? Being preassembled would be helpfull since i'm a newb :)

http://www.offshoreelectrics.com/pro...od=hug-e1067sp

Also I know i've been bugging the heck out of you but can you list all the other products I will need besides the cable & hardware to complete the hardware install. Like what size stuffing tube etc. (not even sure what else i need) How about a good prop to start out with? How about reinforcing the transom & the floor of the hull as it's just thin ABS. I know I have to odo something with the transom for sure. But what about the floor? What is the best material to use for reinforcing these areas? Wood or Carbon fiber? Would wood probably be cheaper which the goal here. If so is there a certain type of would you recomend? Should I get soemthing special from a LHS or will somehting from the hardware store do fine?I plan on buying all this stuff from OSE this weekend & then I will start a build thread with pictures.
By the way this boat will not be raced at all. Just tooling around some of the local lakes. I have access to 6-7 different lakes within 2 miles of my house.

I can't tell you enough how much I appreciate your help & knowledge

[tiqueman]

Tabs will work for and are a nice scale look. That Shaft will be fine or you can save a few dollars and get the one I linked you to and select the assemble option for 10 dollars. About 19 total vs 24.00. Id get a piece of ply from the LHS to beef up the transom and depending on what you wan to spend, use fiberglass cloth or carbon fiber to strengthen the hull. There are several ways and methods to apply the material to the hull. Ive used straight epoxy (not epoxy resin) to adhere carbon fiber to an abs hull and it worked wonderfully. Made a HUGE difference in structural integrity. Your LHS will have the 2 part epoxy you need.

Some parts:

a motor mount for a 540 motor (OSE has quite a few to choose from)
Water cooling jacket for the motor
Water lines
Water outlet
miscelaneous wood or equiv. to build servo mounts etc
foam flotation
the .150 if you run it in the liner it comes w/ ( I like liners, some dont) then you will need a piece of 1/4" brass tubing for your stuffing tube.
You will need a push rod for your rudder to servo and connectors
Motor coupler to connect the drive shaft
marine grease for the shaft
I cant remember what the hatch on the SH looks liek, but you will want to make sure you can tape it down to keep things water tight inside. 3M clear electrical tape works wonderfully... hit up Walmart for it.

What motor/ esc combo do you think your going to go with? That will determine the prop selections.

I think I have a set of those tabs layin around. If I do, I will let you know and you can PM me your address and I will send them to you.... One less thing youll have to buy.

[Hi8iS]

Thanks again for all of that. Been looking at everything & will be placing an order this weekend for sure. As for prop sizing I will be using the motor & esc you linked me to. Also do you know of any good pdf files or places that have good info on installing a stinger & hardware on a mono. Like i said I have never attempted this before & want to read up a bit before I wreck the hull. I have put together manybuggy & truck kits & have owned several rtr boats but never built one from scratch. I just got rid of a Herzog Hurricane because I was sick of gas. I learned alot from making adjustments on that boat. But as far as install i'm a little overwhelmed. On another note I was also reading somewhere about a titan 29 going over 50 with a 9xl. My boat is much lighter & was wonderring if it would be overpowered?
As for water pick ups will i need 2 sets. One for the esc & one for the motor? If that is the case would a rudder with dual pickups work better?

[tiqueman]

You can use one pick up. Most boats are set up that way, especially when it comes to RTR. Most common hits the ESC first, then the motor.

I dont think you will be overpowered. My 32" cat on 4S runs about a flat 40mph on a 442 prop. If I went 5S, then yes, Id be closer to 50. I think you will be fine with that set up.

Best advice for set up tips is to go thru the build forums and just read up on what and how people did thier builds. Theres a great one going on now about a hopped up Super Hawaii. I was reading it the other night. Also some ways to get it to handle better. Id read up on those especially and post some questions on there to the guys who are doing them first hand.

[Gexx99]

I just dug up a SH from the basement and was looking to do a similar build. The gear case on mine is blown so I was going to go direct drive. I was wondering if I could use the stock outdrive or will the plastic not handle the power? I dont plan on racing it, mostly just running around and what not. I am on a very tight budget and wondering if it would be best to build this hull up or just buy a RTR and go the easy way. Problem is that I know that the SH handles waves better than most boats that I have tried and I would be running on less than glass water. I was looking into using the motor esc combo that you had suggested above. I dont have lipos.

BTW. how did this build turn out?
