  • Hi,

    What is the size of this stuff??

    All I see on ebay is 2K , 4K , 6K , 12K , 24K , but I'm not sure any of it is proper...If you could send me a link to "anywhere" in the USA for this material of correct size by emailing me here at youtube....much appreciated. Thanks

  • @XRayCam I used 12K carbon tow. I have sense used fiberglass strands pulled from some

    fiberglass cloth that looked about the same in cross section and it worked great too. On one of my radian fuselages I used clear box/mailing tape. That worked great too. The tape helps to keep the fuselage from getting banged up on the bottom side.

  • Great build! We use wingstays to secure the wings. see them here on youtube.

  • nice mod ,nice and Pro like...Ahh do oyur doctor perscribe you popcycle stciks as well.My doc would Prob laugh at me and say no lol if i asked for stuff liek that.

    what do you tell him you need Needleless syringe for?

  • She's an old friend that knows me and knows that I need them at my day job. I squirt dye with them to find underwater leaks.

  • @leaktech1 Im going to get the Radian Pro soon.the PNP version.

    it seems they fixed/mods that alot of people did too the Org Radian.

    I just built a Scratch Built Glider. called OSG ... 60'' Wingspan ,shes a 3Ch made from 1 20x30'' 4mm sheet of Readiboard from the dollar store,hence the name (One Sheet Glider)

    I think the Flap and AIl additions too the Pro well make the already amazing plane

    even better. ;0)

    heres the build on RC groups...

    i have a vid of the maiden on my Channel ;0)

  • I built the OSG too. Look for Leaktech on Springers build log. Have much bigger gliders now. Just finished a 3 meter span Mirage. Working on a 96" E power tug this week. Then I'll build a 4 meter foam sailplane. Check my blog at RC Groups to see the wing method. We were able to aerotow the OSG but it's hard to keep straight behing the tug due to it's small size and light wing loading. We even aerotow up an old Radian that I cut the front off and installed a release. Checking your vid now. : )

  • Great Mod...

    Pitty I cann't get any of this "CST carbon tow" over here in Ireland...

    Could I use just a singal 4mm Carbonfiber tube underneath the tail....

  • Hi Sean, I got a 12,000 yard spool for $30 US dollars last year. It's a triple life time supply. Just looked at Ebay, they are still listed for 30 bucks plus shipping. Search "carbon tow" on ebay. It's so cheap in tow form. After they make it into a strip or tube the price shoots up a 1000 percent. Is it a banned material in your location?

  • @leaktech1 ...It not that it's banned..It's down to "supply and demand"

    If there no demand for it , model shops don't supply it,Over here in Ireland.....simple as that...Were so backward...LOL...

    !2.000 yard ? I'd only need enought to do your Mod....

    I've just bought a Radian,it's still in the box...

    But I'd like to copy your mod before I take it out to fly...

    Regards Sean

  • Hi Sean, Use what you have. Carbon tow is overkill for this task. Fiberglass will be better because it almost disappears when you wet it out. Pull some fibers from a length of glass cloth. Just about any kind of fiber would work if it's long enough. Cotton, polyester, nylon....etc will work. Around here in Phx AZ there's palm trees with long fibers in the leaves. I'm sure there is something you can use in your location.

  • @leaktech1 ... found a company that sell Carbo tow in the UK :-)..

    Just waiting for a E-Mail on what gauge they have in stock...

    Thanks again for the replys..

    Regards Sean

  • I just cut mine at the factory joint in the rear, used a hot metal rod 1/8" dia and poked a hole foward and backward. Used a slightly larger 1/4" dia fiberglass rod which is super light and flexible, made my fuselage bulletproof!

  • Did you get the 3k, 6k, 12k, or 50k from CST?

  • Yes.

  • What is the difference between the 4 types?

  • 3k is 3000. That's 3000 fibers in the tow. So 50K has 50,000 fibers in it. In the video I was using 12,000 tow, it's about 1/4" wide. 12K is the most popular size folks use. I've used up to 162,000 in a big 10' span model. Keep in mind that carbon on one side is not very strong. But on both sides it's amazing. Think of an "I" beam when you use it. In the video the middle part of the "I" beam is the fuse. The fuse could also be called the web or shear web.

  • Can you post a link to the place you bought the towfrom?

  • Google "CST carbon". Then go to products.

    Youtube won't let me post the link......don't know why?

  • No carbon on the wings. I did put some on the little tiny area next to the slot the stab slides through. There's very little foam holding the fin and rudder there. Not sure it's needed but the weight gain was only 1.5 grams and I needed some weight back there to balance anyway. Lots of pilots have added a coin back there so I put the weight to good use.

  • Did you place a piece of carbon tow on the wings?! I noticed your other aircraft, the AP foamie, has the carbon tow on the wings as well as the vertical and horizontal stabilizer (Nice vids of that as well)

  • did you notice a difference in the way it flies? I'm curious, because I considered doing this before happened upon your video.

  • Yes response is faster.
