FlightClub PROton-R

What do you get when you combine the experience over the past 3 years of designing frames and feedback from some of the fastest pilots in the world?  You get the PROton-R.

The PROton-R is the evolution of an already great race frame, the original PROton, into a frame that puts it in it’s own class.  FPV racing is hard enough.  The last thing you need to think about is a frame with shortcomings.  The PROton-R is a frame you can count on so you can focus on winning races.

  • 1 screw arm replacement vs 2
  • 4 threaded holes instead of Butter Mounts
  • 5mm arms vs 4.5mm
  • front standoffs moved forward 3mm (more room between camera and stack)

  • Neutron-R and PROton-R use the same arms, camera mounts, antenna mounts, HD camera mounts and Airbender
Nucleus Plate

The nucleus plate in the PROton-R is milled out of a solid 4.5mm thick 7075 aluminum plate (PROton uses 3mm).  Through cleaver design, the plate is strategically milled out in certain places to save weight.  But an extra beefy 4.5mm thick where strength matters such as in the arm channels.

The arm channels tolerances have been meticulously tweaked so the arms slide in with virtually zero movement at all.  Changing an arm only requires removing one screw.  This equals rock solid arms with no flex or wiggle.

There are a total of 12 threaded holes in the PROton plate (6 for the arms, 4 flight controller screws, 2 front accessory) to make building and maintenance a breeze.  No need to mess with press nuts or locknuts.


Instead of Butter Mounts, the flight controller is now 4 threaded M3 holes.  Virtually all 20×20 flight controllers now have built in soft mounting so the Butter Mounts are not needed.  Having threaded holes for the flight controller making building a breeze and there’s no need for locknuts to secure the stack.

Hybrid Geometry

The hype is real!  Hybrid geometry is running stretched X on the front and longer true X arms in the rear.  This makes the frame incredibly confident inspiring and smooth in the turns.

The channels for the arms in the Nucleus plate is designed for SX up front and X in the rear.

There are two arm options.  Both are hybrid geometry.

  • 5″ Hybrid – same 5″ arms for front and back
  • True Hybrid – 5″ front, 6″ rear

The 5″ hybrid is great for people who just want to carry the same arm for both front/rear.  This makes replacements easy.

True Hybrid is for the people who want the true hybrid setup with 5″ SX and 6″ true X in the rear.  You’ll just have to carry two different arms for replacements.

Dead X

Dead X flight controller mounting is having the flight controller stack exactly in the center of the 4 arms.  Most frames offset the flight controller stack back to make room for the camera.

Milliseconds count!  This could make the difference between 1st or 2nd place.

Top Plate or Canopy Pod

The top plate now has two accessory ports, GoPro mount and the Airbender turtle stick.

The Airbender turtle stick is an alternative to fins.  Using a 3.5mm carbon fiber rod and 3D printed mount, it weighing just 2g.  The Airbender is virtually aerodynamic causing almost zero drag and impervious to cross winds.

They hybrid pod is designed by MaydayFPV.
