Scratch Building Your Own RC Planes Episode #3.5 - Fiberglass Wing Tube Sockets
HTML-код
- Опубликовано: 11 сен 2024
- In Preparation for making the foam core wing, we will need fiberglass wing tube sockets to house the aluminum wing tubes. This video shows how those fiberglass socket tubes are made.
This is one of several videos (Parts) that cover the complete wing build process: Use this list for quick reference:
1. Cutting the cores
2. Drilling the wing tube sockets
3. Installing the wing tube sockets and false rib
4. Sheeting the cores
5. Making the lightening holes
6. Leading/Trailing edge installation
7. Cutting the servo pockets
8. Making and Installing the root and tip caps (part One)
9. Making and Installing the root and tip caps (part Two)
10. Making the Ailerons (Part One)
11. Making the Ailerons (Part Two)
12. Robart Style Hinge hole drilling and Installation
13. Installing Robart Style Pin Hinges
14. Making and Installing the Carbon Fiber Aileron Linkage
So, we have a lot to cover. I hope you enjoy the journey and pick up some tips.

wow....amazing content... please keep more videos like this coming!!
Hi Mike. I want to say thanks. Last night I saw this video and attempted on a carbon tube instead of aluminum mandrel. But it came out perfect. I used 10 inches of plastic rolled on the tube and it gave me perfect shim gap. The tube slides perfectly with no rocking. Keep doing great tutorial videos.
That's great to hear. Be sure to join the FACEBOOK Group RC Foam Core Wings for more information and progress on the project.
@@mikencrcf6018 sure
your a great builder thank you for putting your work out there for people to see i would like to get into building them for people to get into people need things like this to have joy in life.what would you charge me to build one for me i want something for me an my family someyhing to do together
Thank you so much.
Check out the Facebook group RC Foam Core Wings for more on this and other similar builds.. and the website rcfoamcorewings.com.
The website is under construction so ignore the clutter. There's still some good stuff there though.
Thank you Sir. Very helpful
Very good video.
Thanks a lot for this video 5*
Absolutely. More coming soon.
-- What weight fiberglass mat do you use for wing tube guide?
Thank you!
I’ve helped to make a few of those!
Yep. That's actually your BushGnat in the opening scene of episode one. It has a RCGF 26cc. The one I'm flying is mine with a RCGF 20cc. I actually like the 26 better. My next one will have a 35cc.

I assume you mean Lilah? I didn't realize she was in that episode. She's my buddy for sure.
Awesome! I really appreciated the how to. If I may ask what is your cloth weight?
Generally, I swap off between 6 oz. and 4 oz. Both will work fine. Obviously, the 4oz will clean out a bit better and end up a few grams lighter. The 6 oz. will be a bit stiffer. So, there are trade-offs but honestly, the differences are very small. I've even used 2 oz. in a pinch with success although it was a lot more flexible. However, I'm not sure how significant that is since the tube is ultimately locked firmly inside the foam wing with epoxy.
If you are ordering fiberglass cloth, we will be using .75 oz. cloth on the wings and tail feathers later. I have used 1.4 oz. on the wings as a comparison. the 1.4 oz. handles much easier but again its heavier. I use the 1.4 oz. on all of the flying wing planes since its so much tougher.
You are welcome to email me at cpd551@gmail.com for easier/faster correspondence.
Definitely going to give this a go thanks for the info ,,what was the weight of the cloth you use
I use .75oz cloth on the wings and 4 oz or 6 oz on the wing tube sockets. I see very little difference between 4 and 6. I use whatever I have. You will wipe all the epoxy out that you can.
Join the FACEBOOK Group RC foam core wings for tons if info and conversations about using these builf methods.
can i use the backing sheet that we get from the covering films to separate the wing tube and the glass guide?
I'm not sure about that. I'm guessing you're using Ultracote or one of the coverings that uses that waxy backing? Try a quick test with some epoxy. If it sticks you'll know the answer.
Wax paper is so cheap here that I've never had to worry about that.
I will add however that I have seen issues with some of the cheaper wax paper. It still comes out comes but it takes a bit more persuasion.
Great video. although I do have a couple questions. approx how much epoxy do you mix per tube and how many wraps of fiberglass are you using?
I use the West Systems epoxy with the pump system. I use one pump per tube. I dont know the exact amount but it looks like about 1/3 of that little 2oz cup.
Dont worry about using too much (other than wasting of course) since you will wipe off any excess. Its very important to remove all the excess you can get out. You can't remove too much. It will still be extremely strong.
I generally make three wraps with the glass. Some thicker glass could get away with two wraps.
Three is my sweet spot though. The epoxy is where the wgt is. So, get all of it off you can.
@@mysticsmokers3014 thanks for that. I do have the west systems epoxy. So that makes it really simple. Any idea on how many wraps of fiberglass? I have some .75 which is too light. I have some 3.7 which is what I planned to use. I also have some 5.7 carbon as well but thought that was a little overkill. I am scratch building a 50cc Ultimate bipe, thanks again
As stated above, I use three wraps generally. Thicker glass can get away with two. There's realy no pressure on these parts so dont get to heavy.
Join the FACEBOOK Group RC Foam Core Wings. Its the supplement grouo for this project.
We can add photos, videos and other media there to ask and answer questions.
Also, there are many other guys that can contribute to or benefit from such questions.
@@mikencrcf6018 thanks for the reply. I watched the vid more than once. there was mention of wraps of the wax paper. However, no mention of the wraps of glass. In addition there is no mention of any prep on the tube prior to layup. Might not be needed on 1" aluminum tubes. I found that using smaller tubes such as 18mm carbon fiber in my case. a few coats of car wax on the tube makes removal of the tube easier. But other than the questions I had still an excellent video on how to make wing tubes. Thanks for sharing

@cforcht
You're right, after reviewing, I didn't specifically state three wraps on the glass.
In my defense, its essentially the same width as the wax paper so one could reasonably assume the same number of wraps.
Like I frequently say, "it's not rocket science". This is a "no load" part that simply acts to guide and contain the wing tube.
Using CF tubes can get a bit more difficult depending on the surface condition of the tube. More dimpled tubed can get tricky. The resin actually shrinks a bit as it cures making the wraps tighter. It can make removal more difficult.
You're right, wax does help in those cases.
A good smooth aluminum tube needs no preparation.
The Gnat project is basically a flying tractor. A CF tube wouldn't make sense for my flying style. I've bent several aluminum tubes with little to no wing damage at all.
Very helpful! What is the Material thickness of the Rods?
I use 3mm carbon tubes or carbon rods for the fuselage reinforcement. I get them from Windcatcherrc.com. There are a good many distributors out there but the rods and tubes I get from them are always straight.
What weight cloth do you use for the socket?
I use 4 or 6 oz for the tubes depending of what I have. I see no real difference between those two. Go to Facebook group "Foam core rc plane builds and repairs" for more details. Its much easier to talk there. Its a groups for these builds. Feel free to join.

How thickness the wax paper is? I have some 0.04mm on hand, is it suitable?
The box does not say. Internet says it's. 025" I checked and that is correct. Since I use three wraps, that's . 075" if you use two wraps, .080 should be perfect.
Many thanks for your prompt response, it really helps
Absolutely, its easier to correspond on the Facebook group dedicated to this project. This is a perfect question for the group to benefit from and help answer. "Foam Core Wings"
@@mikencrcf6018 A perfect tube has been made according to your instructions, many thanks!
@@taowang6354
That's great to hear. What are you going to use the tube on?
Would you ever sale a complete jig set for this plane.
Yes, I could sell a set of templates for the plane. I haven't given much thought on exactly how that would work out yet but several guys have asked. I have sent traced drawings of the templates out to make it easier for making templates. Once you start making templates, you find that its really easy.
How could I get the trace drawings that you have sent out. And if you decide to sell a complete set of jigs if you would let me know I would be interested. Thank you for your time.
Mike great build! I have used gallons of west systems the 105/and 207. Instead of paper towel maybe a cheap plastic putty knife with a half cut (the diameter of your finished size tube) in the end would make faster cleaner removal of the epoxy as you are only wanting to wet the glass and remove air from the fiberglass. Your the master and I the mortal but thought it might help. By the way thank you for your willingness to share your passion with the masses. I know how much time videos and text can take. And FYI the putty knife can be used over and over as the epoxy will not bind to it. Just let it dry hard flew the knife it will pop right off
Flex the knife
I thought I had already responded to you but I don't see the response. If you email me at cpd551@gmail.com, we can arrange getting you what you need.
Thanks,
Mike
Hello do you sell the plans for this plane?
Sorry for the delay. I have provided many free PDF copies of the traced templates to guys who have asked. I have mailed hard copies to guys who don't have access to a 4ft. printer. Just pay the print and shipping costs ($20) and Ill get them to you.
@@mikencrcf6018 okay thank you. Who do I make payment to?
@@racnc1 Can you join the FB Group RC Foam Core Wings? its easier to talk there. If not, email me at cpd551@gamil.com
