FlightClub PROton Race Drone Frame

PROton in Skeleton Mode – 215g


Designed from the ground up to be a race drone frame, the FlightClub PROton can adapt to any situation.

proton cnc nucleus plateAt the heart of the FlightClub 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. 

The PROton is available 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.

PROton Highlights
  • Nucleus Plate CNC’d out of 7075 Aluminum
  • Can wear a canopy or skeleton for people who like building with standoffs
  • Threaded holes in the Nucleus plate for easy arm replacements.  No nuts or pliers needed!
  • Has 30.5×30.5mm and 20x20mm fc mount holes
  • Butter Mount for a vibration free flight controller stack

  • Countersunk holes on the bottom of the frame for a completely flat bottom
  • Camera protection in both Canopy or Skeleton mode
  • Camera Angle approximately: Canopy 30-80, Skeleton 0-80 degrees
  • Approximate weight range 70 – 80g, depending on the configuration
