  • Excellent toy for naughty behaviour.

Excellent toy for naughty behaviour. Use as recommended, of course.

  • Great reinforcement for foam RC planes.
Size: 0.5x5x420mm(6pcs)
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. ... show more

  • Acceptable tolerances
Size: 0.5x5x420mm(6pcs)
These were purchased for a scratch build RC project. Although the tolerances are acceptable, one of them was twisted ( didn't lay flat), but that shouldn't affect most situations. If you're like me you get a little giddy when you order carbon fiber pieces :-) thank you Amazon!

  • If this is really carbon fiber, I'd be shocked...
Size: 4.0x20x420mm(2pcs)
If you plan on drilling holes or shaping radius corders, DON'T buy these. I expected better strength from 3mm thick carbon fiber...these are junk. Learn from my mistake.
