Building the rear wings

[Ayles]

Since I am new to this I need a few tips or direction to a thread on how to assemble the fiberglass rear uprights and wing from Rc boat company. I have all the parts just not sure how to put the
together and if there is any framework that goes inside.

thanks!!

That does look nice, I read some threads where one guy used 1/8" aluminum for the mounts but when I got the plate it seems way to thick so I ordered a piece of carbon fiber hopefully that will be more suitable.

Not sure why that person is using so much more glass mat to reinforce them. They don't seem flimsy at all.

Make sure to put some foam inside of them to make sure they float in case the worst happens.

[Ayles]

I have some half inch closed cel foam from a car restoration I did a while back. Any reason why I couldnt cut it into strips and use it in the wings? Will float and not soak up any water.

[1coopgt]

That should work good.

this is the best floatation for feathers and wings.
I realy liked the aluminum rods from RC Boat works ran at a 45degree angle from center to wing.

It would be nice if the Rod kit was available. I've been waiting for them for a year now to become available.

After I bought it once I have built my own since then. I do not use the big plate in the middle just ball links to the transom. I use break away tooth picks in the feathers to deck mounts. all the rest of the parts come feom Dubro.

What retains the toothpicks?

What retains the toothpicks?

What I do is when you drill your holes use a 3/32 drill bit. Get round tapered Tooth picks. Take one in each hand and from each side of the feather push the tooth picks intill they stop, you have to push hard to wedge them in. then use wire cutters and clip each side. Then do the other three holes the same. They will stay in the wing untill a crash, they will break away no harm to the Feather or mount.

As far as the support kit goes, I have been on the list to buy one for several months. Apparently the guy that makes the bracket on the transom has been ill.

I'm planing on using 4-40 nylon/plastic hardware to mount the wings. I pressed 4-40 pem nuts into the carbonfiber mounting tabs on my boat.

That might work , It might also rip the wing or damage the paint

[1coopgt]

Not quite sure how it would rip the wings or damage the paint. But stranger things can happen i suppose. I won't be racing the Hydro, no clubs around here. The plastic or Nylon screws are pretty soft and will snap. 4-40 screws aren't very thick. These were recommended by the folks over at Inlwaters.com . Very knowledgeable folks over there when it comes to Hydros.They tend to specialize on Hydros from going through the forums over there. Kind of like Offshoreelectric.com tends more towards Cats and Mono's

[Ayles]

Lots of good points here! I got an order of nylon hardware and carved up some closed cell foam to fit. Also made a template for the carbon fiber mounts and cut some fiberglass veil to reinforce where the mounting holes will be drilled.

Might as well dive in!

[T.S.Davis]

The last set of tail feathers I did I built them out of wood with layers of carbon. Sort of a hi-bred composite kind of thing. Strong as a brick poop house. Used nylon 440's to attach to the plates at the deck. Crashed......made an absolute mess of course.

I like Randy's thinking. Set them up so they can come off without wrecking themselves or the boat. Just enough to keep them on while racing.

[Ayles]

I went for it last night and epoxied the halves together with a chunk of closed cel foam in each. Used gflex with a little filler. Once the cure time is done these are goint to need a bit of sanding since they dont fit perfectly together, but it’s probably not going to take much.

[1coopgt]

Looking good.

[Ayles]

Ended up needing a bit of filler on the exterior of the seems. I think they turned out well considering I don’t know what the heck I am doing :)

[Ayles]

Whipped up some carbon fiber mounts for the rear:

I felt steady enough and went up on a step ladder and took some pictures.

I could not get my son over long enough to get it down.

Funny I took the pictures with the camera all the same. Some how it flipped loading to the site.

[1coopgt]

Looks good thanks for the pics . Stay safe. Don't want you getting hurt on my account.

You can get foam core ready to mount wings from me too.

Those do look nice!!

Do you have a wing support kit?

Asking the important questions.

Thanks for the Link to your site Phil!

See the wing setup page all the parts on there

FINALLY. You would think I just found a new religion.
I asked RC Boat Company over a year ago if he could please make a video and post it to YouTube and describe what to do with the fiberglass vertical and horizontal wings. I’m still waiting like over a year later.
Then I asked Scott Meyers (M5 Performance Hydroplanes) if he could please make a video and post it to YouTube describing how do people assemble the fiberglass vertical and horizontal wings and what hardware do they use to attach the parts together. He mentioned something about wanting to build a lighter scale hydroplane that does not require the rear wings because they add unnecessary weight.
And then I mentioned it to Rattlesnake RC and he said something like you may find it’s better to run without them.
I’m still waiting like over a year later.

I’ve got some hardware and the fiberglass wing parts all collecting dust. It would be nice to know the dimensions of the tubing that people add to the horizontal fiberglass wing to strengthen it. I’ve been scouring the forums for build pictures but there are almost none in regards to what type and size is the hardware.

I bought the 4-40 nylon wing bolts and 4-40 brass threaded inserts to connect the horizontal to the vertical. And 4-40 nylon bolts and brass inserts to connect the vertical to a tab attached to the hull of the hydroplane. I’m experimenting with light green colored closed cell foam I bought at Lowe’s Home Improvement to add some buoyancy to the wings. How much is too much foam I do not know?

Well I did not have much to go on when I did my first wings. There was no one to tell me how to do it. So I just jumped in and learned by trial and error. I can tell you some tips though of what I like. On the top wing I like all thread threw the full wing and trim to fit. For the 45 braces I like to use a closed end electrial connector to go threw one of the all thread on each side top. that is on a dubro 4-40 servo rod that is slid in to a aluminum tube by K&S and ball joints on the bottom mounted to the transom. the servo rod will slide out of the tube on a crash. tooth picks will break on the wings and this is all to cause no damage to anything. folation? I use kids fun foam one layer to fit in the feathers and wings. Most of the time I don't run wings except in scale and I prefer my 72 Bud over my 78 Blue Blaster

[Ayles]

For the horizontal wing I made it like a model airplane wing. But why not use a piece of carbon fiber arrow shaft?

I haven’t glued it together yet, so still have options if there are better methods.

overall though, I am pretty happy with how the verticles came out. As I said in a previous post… I just went for it with the epoxy. Then sanded and filled with another batch. Keep in mind I am new to this too, never built anytiing like it.
