4mm Arm for FB-01 and Red Panda




Item Description:

A single 4mm thick arm for the FB-01 and Red Panda Racing Frames.

Shave 10g off of your FB-01 build with these arms (arms and shorter screws)! While these arms aren’t as durable as the 5mm version, they are great for high performance lightweight builds. I use them for freestyle and racing.  Each arm has three mounting holes to reduce weight and improve strength of the arm at the neck.
