Use as recommended, of course. Review: Great reinforcement for foam RC planes. - I fly and occasionally crash foam RC aircraft from Horizon Hobby (E-flite). In the past I reinforced the fuselages with fiberglass tape such as used for drywall. I now attach a carbon fiber bar down each side of the fuselage with Foam-Tac. The aesthetics are better and the planes are still crash resistant. I have (unintentionally) nosedived an upgraded Horizon Hobby Conscendo into the turf and it lived to fly again. ## Features - Material:100% carbon Fiber - Width:20mm, Thickness:4.0mm, Length: 420mm - High strength,lightweight - Package:2 pcs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09XBHX3ZB | | Best Sellers Rank | #53,905 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #8 in Carbon Fiber Rods | | Date First Available | April 6, 2022 | | Item Form | Rod | | Item Thickness | 4 Millimeters | | Item Weight | 3.52 ounces | | Item model number | carbonbar4x20 | | Manufacturer | cncarbonfiber | | Number of Items | 2 | | Package Dimensions | 17.44 x 2.36 x 1.26 inches | | UPC | 702401782287 | ## Product Details - **Brand:** cncarbonfiber - **Color:** black - **Item Diameter:** 4 Millimeters - **Material:** carbon fiber - **Shape:** Rectangular ## Images ![2pcs 4x20mm Length 420mm Flat Carbon Fiber Bars,Pultruded Carbon Fiber Strips - Image 1](https://m.media-amazon.com/images/I/51LaKDvbruL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent toy for naughty behaviour. *by M***S on December 24, 2025* Excellent toy for naughty behaviour.
