I bought these to go on my CL-415. Needed a bit of balancing but otherwise OK. Not visible in the photo is that the hole is about 1/8" diameter and the prop hub is not solid plastic, but has a center collar and 3 supporting gussets. I needed the hole to be 5mm, so I filled the cavities with epoxy. This keeps the drill bit centered as you enlarge the hole.
