FlightClub PROton Skeleton 5" Race Frame

Designed from the ground up to be a race frame, the FlightClub PROton can adapt to any situation.
Availability: In stock


Designed from the ground up to be a race frame, the FlightClub PROton can adapt to any situation. The FlightClub Proton Skeleton 5" includes the thinner Race arms.

At the heart of the PROton is the Nucleus plate. It allows PROton to be configured into a total of 10 different frames. The Nucleus plate is a CNC milled 7075 aluminum plate that lets the PROton rock either a canopy or skeleton (standoff) mode. The Nucleus plate features threaded holes for the replaceable arms. This eliminates the need for M3 nuts or capture nuts that either strip or are a hassle to swap arms.

Borrowing a design feature from it’s brother Tokio, the Nucleus plate will have Butter Mounts. Butter Mount is an innovative way to mount the flight controller stack using custom silicon injection molded grommets that virtually eliminates vibrations.

Initially the PROton will be released with 6 arm options – 4″, 5″ Race, 5″ Practice, 5″ SX, 5.5″ and 6″. The 5″ arms will come in two styles, thinner Race arms and wider more durable Practice arms. Pick up some spare PROton Arms.

Just like the Tokio, PROton is loaded with details.
