ARRIS 4.0MM Carbon Fiber Rod 200mm Length for RC Airplane DIY Craft 1mm 1.5mm 2mm 2.5mm 3mm 4mm 5mm 6mm 7mm 8mm 9mm 10mm Matte Pole 7.87inch 5PCS

I used these to repair fragil removable window munitins. Cut a grove in broken wood, then glue these in place makes the member stronger than original.

Overall they seem to be good quality with a consistent overall diameter. The rods are smooth and nicely finished with even ends.

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!

Good quality, packaged was wrapped up perfectly

Bought 3mm rods and they are exactly 3mm. Wanted to use this to mount bearings on my 3D Printer instead of heavier steel. The rods are exactly 3mm and the idler bearings ID is also exactly 3mm so these rods do not fit unfortunately. Had to put the rods in a drill and use some sandpaper to turn them down. If someone else needs to do this make sure you are using a fine particulate mask. You do not want to breath in carbon dust!

As described

Used for kite stand offs. A little cheaper than the kite store, although in small size so there is more waste

I used these to repair a kite that we had. They were exactly what we needed.
