Ichabod Jr. Prop Guards
These prop guards pop into the recessed hole in Ichy Jr arms, and are secured with zip ties. Use them on 5" arms, and run 4" props. They are for those times when you need a feeling of security on a shoot, whether it's because you're in tight quarters or near soft targets. The carbon arms are 2.5mm.
Keep in mind these are for a feeling of safety on a shoot, they're not meant to be freestyle bashers.
You can buy the full kit of print the 3d parts yourself. Files are here.
