Default 1/8 scale Hydro Hardware

I have been searching for running hardware items for my 1/8 scale and would like to see peoples hardware setups for their Hydroplanes.
1 /8 scale preferably and where the items were purchased. websites etc...
The only places I have found are AeromarineRC and Niagaramarinehobbies, and NiagaraMarine sells AeromarineRC hardware.
So in escence, AeromarineRC is the only place I have found.

Pictures of Tricked out hydros and hardware would be cool as well...
Thanks a bunch,
Jeff

Speedmaster at www.rossisales.com is some of the best stuff around. I use this hardware on all of my .21 and up boats.

how are you doing on the cowl? I think I read a post about a cowl you were building on the airplane side. I eventually want to build my own cowls for my own hydros I was wondering if you can give me any info. oh yah I think that Aeromarine has some pretty good hardware, but thats just my opinion.

@ ByronRC, Cowl is fine - got the answers I needed for the part numbers and styles of fiberglass too use, crows foot etc..
It is actually pretty easy to do, I am finding out. Just time consuming.
I'll answer what I can.

@ Ron - Looked at Speedmaster stuff. Very sharp looking, Nice and Shiny. Might give them a try.

Thanks for the replies.
Hopefully have hardware, boat and canopy done in the next three weeks!!!!!!!!

Nobody has any pics of their hydroboat hardware though???

These guys have quality stuff, that always works well. A lot of stuff I made custom, but for struts, rudders, props, flex shafts etc. they have good stuff.

The cowl is hand made from a mold using carbon fibre reinforces kevlar. The various parts I milled according to photos I had taken at the thunderboat races when they are here i San Diego. For example the turn fin on the real boat has three steps in the blade to keep the weight down. I milled it to look the same and then had it hard black anodized. The standoff and wing brace on the back of the boat was also a hand milled and welded piece anodized gold to match the real boat. The rudder was modified as well as the strut to look more like the real thing.

Two More - First things first, I used liteply for the pattern of the top of the boat. To get the convex shape cut into the base of the foam plug. then added the other two pieces, glued and created the side profile patterns and used a hot wire foam cutter to make the initial shape.
Then rough shaped with dremel and hand foam sander.
Filler was used as a hardener. Drywall Compound. Wored great. Now I am at the process of Fiberglassing it for the Form to make the final piece. DO NOT use fiberglass resin for the initial work on the plug. I purchased West Systems Epoxy and 3/4 ounce Crows Foot fiberglass mat.

Should work good, will let you know with pics on completion of project.

Anymore questions, let me know

Jeff

Byron RC - Thanks for the compliment. It is actually pretty easy I am learning along the way. I will be using 3/4 oz crows foot fiberglass mat and west ststems epoxy. then sand smooth and paint. Then I will wax it , a couple of coats and then apply fiberglass with west systems for the mold.
Then use fiberglass resin for the final product.

Default RE: 1/8 scale Hydro Hardware

I just did a continuance of the thread I have in Composites but,

I just finished a redesign. The shape I had came out to be to difficult for the parting board. It would not slip on and off without tearing up the plug So I made a new one it has air intakes on the side.

(The form would have worked if I had created two different fibreglass form shapes and joined top and bottom later..)

Started all over and have just finished the initial fiberglassing, This shape does not need a parting board as the plug will come right out.

Blow compressed air in to release and it will pull down a half inch in the back and drawn out through the rear, I am hoping anyway.

Find out tomorrow morning

Well, It worked - The one in the back is the mold / West systems epoxy - The one closest is the fiberglass canopy - fiberglass resin.

Just need to do final trimming and then sand and put in the wood reinforcments.

Hydro Junkie, Yes it is the Atlas Van Lines. I know I should have done it in the scale scheme but what the heck. I am different - Fitting it with the hardware tonight. Only thing left is the tuned pipe I have to buy it this week. I was buying the OPS tuned from AeromarineRC and they were out of stock / Luckily / Ron Olsen told me that it would not be sufficient.
I am getting the Parabolic .67 tuned / muffled pipe from CMD Racing.com.

First test run will July 2nd -Can't Wait

And just what's wrong with being creative? I couldn't leave a set of Newton's plans alone, so the only part that hasn't been changed to match the real boat is the sponsons. Needless t say, it's been a lllllllllooooooooooooooooonnnnnnnnnnnnnnnngggggggg ggggggggggggggggggg project[sm=drowning.gif]

Well here I go, Pipe is on order from CMD Racing. Got the AB 67 black tuned unlimited pipe. They Say it will work wonders for the engine.
Just mount it next week and off to the pond. ( in another state...)
Too questions, How far must the turn fine be below the sponson to work appropriatley. I have mine set at about an inch plus I have curved the end / bottom in toward the boat. Saw that on another boat and thought it looked interesting.. and how much rudder authority do I need for turning, I have it maxed in the area I have - see attached photos, will it be enough for turning agressively

Thanks for the input.

I wish you would have asked about the radio/rudder install before it was done[sm=eek.gif] A rudder works best when you can pull the rudder rather than push. I may get some flack over this, but in all the scale hydros Ive been around, I've only seen a couple with the rudder set up with a right turn push. The reason for this is you are normally going to turn right, so if you pull the rudder, you have little to no chance of bending the pushrod. As for the skidfin, there is no hard and fast rule, though a bracket with a slotted upper hole would make experimentation with angles much easier. Let us know how it goes at the lake, as I love it when someone can prove me wrong

@ejp67 - Still trimming the cowl to fit,I was a little off on the finished mold, Must have bowed or something??? Should have it done tomorrow and I'll shoot a photo for you.

HydroJunkie, I understand what you are refferring too but I think I might be OK. I have two servos linked together for the torque side of it, I am utilizing a thicker connecting rod - 4-40 size, but it still has a little buckle when I put force on it so I am going to run a piece of brass tubing with two points of contact that the push rod will slide through. This will correct any bowing problems as it will make it very rigid.
Will definately let you know how it runs.

By looking at the photos of the rudder, Do you feel that it has enough right turn it to turn the boat adequatley?

I was just informed today by CMD that the Black finish AB .67 pipe I ordered is no longer made in Black finish, they come silver now. They stated the coating was not making any difference on running cooler so they did away with it.
I was a little bummed but I think the silver will be just as cool.

Got the pipe today!!! What great service from CMD Racing.
Engine runs great.

Does anyone have a connection for .60 OPS parts. I need a spare Piston Rod. VENDORS do not carry the parts for this engine anymore, been down that road!!

Default RE: 1/8 scale Hydro Hardware

OK Here is an update. Took it to the lake, First couple of runs were horrid!!
As soon as it was launched in the lake it bogged down to about 1 mile an hour. Idle speed at best, everytime I hit the throttle the engine wanted to die.
I proceeded with the common adjustments as prop depth etc. and still no change.
My brother suggested changing the prop I had to a smaller one.
I have an Octura 462 two blade on it now.
He had a Prather 260 with him that was too big big for his tunnel hull., after a little slice and dice on my finger trying to get the new balanced and sharpened Octura off, I put the Prather on.
I could tell right away that the engine had more RPM's.
He did the initial toss in the lake and it took off like a rocket but died about a hundred feet from shore., Buy this time the wind was picking up and we were getting some waves.
We wanted to try it again so I started it up, he launched it, sprayed him pretty good with the water / roostertail and it took off again dying about a hundred feet from shore. Too windy too continue.

I think we are on the right track with the Prather prop and Octura is way off on the 462 recomendation.

Boat comes out too 10 1/4 pounds.
Sits light in the back as you can see in the picture but we had fun just the same.

Any recommendations are always welcome.
