The 3B-R 211 Frame kit comes with 5mm thick arms that support 5-6" propellers. This kit also comes with angled arms 3B refers to as "Forerake", simply meaning they are not straight, they raise the motor mounting distance from 211mm of the straight arms, to 215mm with the "Forerake" arms.

High-quality 3k carbon and military grade epoxy mean you are getting an ultra-durable frame. The edges of the carbon are also slightly chamfered (rounded) to prevent damage upon impact.
