Hi Nick....
As you I'm new to the RC FE Boat scene....LOL But I have been learning a lot here on various forums as I build my Miss Elam.
http://forums.offshoreelectrics.com/...uild-Miss-Elam
The boat is actually one of ML Boatworks Extreme 171 kits. Its actually been a dream to build. Its being powered by the NEU 1527 1.5Y on 10S, ETTI 220 Pro ESC.
As others have said it seems to be the race package that has been proven and makes the boat quite competitive. Most of my hardware was from Speedmasters except the turn fin that was crafted by Dick over at Virginia Craftsman. Canopy, Turbine tray, dummy turbine and wing strut assembly is all from Steve at RC Boat Co.
Even though I have been an RC aircraft builder and flier for ages...this is a whole new ball game for me, but the folks here on OSE have been great to learn from.
I also understand your concern of missing some detail that can cause a bigger problem down the line with the build or when operating the boat. Mine exactly!!
But I have found that asking a lot of questions and reading a lot of different forums (even other sites) will give you the answers your looking for.
BTW....I just ordered a set of graphics from Mike at Thunder Boat Graphics. He is great to work with, but he is very busy with the business. He does a lot of other graphic jobs other than RC Boats. It is looking like it will be 3 to 4 weeks for my graphics, but call him...you should be able to get your order in. I believe he just hasn't had the time to even update his web site yet....LOL He also races and builds, so he is also a wealth of information.
Good luck on your build....I'll be following. Feel free to ask anything....even though I am a newbie also, I might have the answer but I won't give ya made up one....LOL I'd just refer you over to one of the other veterans if I'm not sure.

I heard that the Accu-tech 1/8 scale turn fin I bought doesn't actually work or mount with the T5 hull, so I need to purchase a difference bracket, I was going to go with the Virginia craftsman one.
But your hand makes me feel a whole lot better going forward, even if you are indeed rather new to this like I am, your several steps ahead of me with your build and Ill probably end up picking your brain quite a bit if you dont mind :) Ive already gone through your thread several times, haha.
I know I stated earlier that im going to go with the Miss bud, but again now im undecided. I need to find out to what extent I can actually have painted onto the hull, and what im willing to turn to vinyl and decals for the rest of the graphics. Theres a certain few boats that I really really like, however the complex paint schemes lead me to think I should go for something else. Also, this may sound petty, but I sort of want to avoid any teams that have already been done by Pro Boat. Lol, the custom aspect of this is important for me to convey.BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment

So I actually ended up purchasing a Leopard 5698, along with a Swordfish hv240amp ESC. There was a really good deal in the swap shop for the combo, already wired with a water jacket, so I couldn't pass it up. Hopefully I dont have any problems with the controller, its refurbished. The motor is brand new however. Its already been shipped out and I should receive it tomorrow. I also finally got confirmation from Kintec that my package from them has shipped.
I also just placed an order here on OSE for some of the last remaining hardware ill need to stay active in the build, and ill make another order or two for the subsequent required hardware and radio gear as the build progresses. My budgets a little tight at this point so I dont want to purchase anything non-essential. But heres everything ive got and also ordered so far:
Hardware components:
The hull (will be here on Tuesday)
Accu-tech rudder assembly
Accu-tech scale strut assembly with bushing
Accu-tech turn fin assembly
1/4" flex shaft with 3/16 step down (just ordered from OSE)
Octura Large Drive Dog for 3/16" Prop Shafts (just ordered from OSE)
Octura Coupler Flex Hex 8mm to .250 (just ordered from OSE)
Teflon Liner for .187 flex cable (just ordered from OSE)
5/16" and 11/32" Brass stuffing tube (on its way from Kintec Racing)
Leopard 5698 with 5650 water jacket (on its way, should be here tomorrow/Monday)
Swordfish hv240amp ESC ( on its way with motor)
Aluminum 56mm angled motor mount (just ordered from OSE)BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment

You really can't run teflon liner for a .187 cable when your using 1/4" cable :) I don't know of too many guys that run liner as we use 5/16" tubing greased well for 1/4" cable. You want to use 11/32" brass tubing glued in the hull and then 5/16 tube for the shaft. Remember that the 5/16 tubing runs from the back of the strut to within 1/4-3/8" of the coupler on the motor. What KV is that Leopard btw? You can use the accutech skid fin mount if the sponson transom is 90 degrees to the ride surface, if the transom is angled, then you will have to use a Virginia Craftsman mount. I do hope your motor mount supports both ends of the motor. This would be the mount I would suggest as it also provides a place for the speed control. You don't have much room once you get all the gear laid out.

But ya, I purchased the 11/32 brass tubing specifically for the exterior reinforcement, I had noticed the discussion in Speeds Elam thread and figured thats a good idea. Do you guys just use a dremel/rotary power tool for cutting the shaft and strut slits? This has been probably my biggest concern, id really just hate to mess up this hull ive invested so much in. Ive made mistakes in measuring or angles and alignment before with custom computer chassis and cases that really resulted in a ton of frustration and extra work, I really want to avoid that kind of thing with this.BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment

Now that majority of all components and hardware are here, I am going to start all the prep and modifications to the hull. This is where I basically need the most help obviously, so ill ask as many questions as I can and post as many pictures as I can. Hopefully, I can get some helpful info and tips from some local builders, im going to attempt to contact a few, and if they aren't too busy and dont mind me picking their brain, ill be up and running in no time :)
So I plan to go to the local hobby store or hardware shop and pick up some lite plywood or Balsa, and some styrofoam so I can add some flotation and doublers to the cowling, and I have also been thinking of using some small circle magnets to attach it. Then I want to craft a bulkheads at about 8-12 inches from the transom of the boat, and another running across the center of the cockpit. Then ill epoxy a wood square stick on each side of engine well to form a lip, and make a flat cover to seal off the compartment from the rest of the boat, and ill be able to start accomodations for the motor, stuffing tubes and shaft assembly. Does this all sound okay?
Is there any specific order in which I should go about each assembly? like should I mount the motor and such before cutting and mounting the stuffing tubes/flex shafts?
Im also pretty concerned about the rear wing setup. I really want to have the angle and attitude of it to be absolutely perfect, and im a little confused in reading the instructions Phil sent me on how to craft the tabs. I was thinking of just buying some of the carbon fiber tabs that Steve has at rcboatcompany, but they are pretty pricey and seem to be a better option before the actual hull is built lol.Last edited by nichismo; 04-02-2015, 06:14 AM.BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment

Nick you can use a drill to make slots but the dremal tools will cut a line. Be careful if using the dremel tool dont let the bit chatter or you will make a ragged hole.
The botttom of the wing verticals can be slotted with the drill or dremel just about 1/16 of glass to cut thru, use the drill to mill out the foam core for the tabs to fit into.
You can make the wing mount tabs with some 5 ply 1/8 plywood that is strong enough. The tabs fit thru the deck slots and sit on the bottom of the hull, they are at an angle. assemble the horizontal onto the verticals to check how they fit before glueing. Cut on the marked lines and epoxy the bottom and at the deck line.
Mount all the hardware first then worry about the motor position to get the balance close. You can position the batteries or add weight to the sponson tips in the flotation foam tubes if needed.
Mount the strut then the motor, cut the shaft slot and gule in the tube. Do it this way so you are aligning the shaft to the motor not the motor to the shaft, it will come out centered perfectly.Comment

thanks Phil! I was actually going to text you today and give my thanks again for boat, it really is wonderful and im very excited to go to work on it.
So ill probably get the holes for the stuffing tube, rudder, and strut assembly cut today, and whatever else I have time for. For the stuffing tube slot, I was thinking of just using the 11/32" drill bit and drilling 2 holes and then just using either a dremel or razer saw to remove the material inbetween. I suppose ill have to take a conservative guess on the space inbetween and then adjust from there. I have almost all my hardware EXCEPT for the motor mount, should I wait to receive that before I cut the stuffing tube hole, so I can cut the appropriate size relative to the angle of the motor? or can I proceed with a general idea?
When drilling, do I need to clamp some sort of support underneath to keep the holes from burring? Also, im worried about keeping the hull stable when I go to work.
May I give you a call sometime this weekend?BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment

I would wait for the motor mount before figuring where the slot would be cut. work on the strut rudder mounting first. there alot of things to do waiting on the mount.Comment

Okay, will do. I just ordered this mount here off OSE, and the rest of the supplies and tools that I may need until I begin with the radio equipment.

im going to get started on the holes for the rudder and strut assembly. Ive loosely assembled them to give me a good idea of placement. Im going to cover the back transom and floor with some masking tape, and then use a pencil to make a mark through the mounting holes of the brackets.BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment

Looks like a good mount you can slot the floor and epoxy it into the foam core. I pretty sure the hull is marked for the centerline for the strut and the driveshaft.Comment

gotcha, I recently used a step drill bit for the first time, as I needed to make 6 holes 22mm each in diameter, in 2mm thick aluminum. I thought it was going to much easier than I eventually realized, but the real problem was my own lack of patience, and also preparation. Even though I only needed 6 holes, I ended up drilling about 14 of them as practice before nailing the important ones on the actual piece. I was so suprised how much just spraying some extra lubricant, and going as slow and precise as possible went toward how far the drill could take me before stalling.
The holes for the rudder and strut brackets are rather small though, do you still file or sand those ones? or do you just start with a small center punch perhaps or indent, and then maybe drill 1 or 2 holes before the final size? Im assuming you guys all use loctite on all the bolts and such?
Im still going to wait until the motor mount gets here, but would this perhaps still be an accurate guideline even with an electric setup? Man im still suprised how big and heavy this motor is! Probably just because its my first FE build, but man I can definately see how these bad boys can muscle up some rooster tails.BIG BOY HYDROPLANES----My first RC boat and build project to boot: (and more content in my profile gallery!) ---- http://forums.offshoreelectrics.com/...proposed-setupComment
