ARRIS 1mm Carbon Fiber Rod, 1.5mm 2mm 2.5mm 3mm 4mm 5mm 6mm 7mm 8mm 9mm 10mm Available, Solid 3K Carbon Rod Bar 400mm Length 15.7inch for Kite RC Airplane Repair, 5PCS

Good carbon fiber reinforcement for my AR wing...see picture

Worked wonderfully for my epoxied in stiffeners for a 3D printed part that the layer lines were oriented wrong for strength and stiffness purposes due to a lack of print volume in the right orientation.

They are pure nice and strong. I got them to repair a free wing 80 mm A-10 aircraft that had the nose knocked off. I haven't yet use these but they appear strong.

Being somewhat of a hobbyist of various DIY materials, I'm always on the hunt for components that promise both strength and precision. The ARRIS Carbon Fiber Rods immediately impressed me with their apparent quality. Right out of the package, these rods felt sturdy and appeared to be very well made, with a nice matte finish that hinted at their robust construction. For anyone deeply involved in RC airplane building, intricate DIY crafts, or other projects demanding lightweight rigidity, the quality seemed top-notch.However, for my specific application, I unfortunately didn't get to put them through their paces. It turned out that the diameter was simply either too large or too small for my needs (as I had to purchase several until I found the correct one), rendering them unsuitable for my particular project. While I had to return them due to this sizing mismatch, I have no doubt that for someone who specifically requires this diameter, these carbon fiber rods would be an excellent choice. They certainly felt like a quality product, and if the size fits your requirements, I'm confident you'd be very happy with their performance and construction. It's a classic case of needing the right tool for the job, and in this instance, it was purely a matter of diameter, not quality.

Extremely useful if you like small rc aircraft I found myself using all of them in the package I really like it's stiffness for it's size and used them all up quickly. I customized full span ailerons on one plane with these and they match the oem carbon fiber rods perfectly on 400mm rc warbirds!

Flexible, strong, and stingy as all get out.

Met my expectations

One of the rods was oversized by almost a mm. Does not work for my application.4/5 were correct.Photos attached.
