This page to present you the custom printed frame I designed from scratch.

Hardware

Presentation:

  • Designed for the list of parts here below.
  • All electronic parts are attached on the body (spacer) of the frame with specific mounts ; some adjustments might be necessary if you want to use different electronic parts.
  • The body and the battery holder are intended to be printed in SLS nylon.
  • The three plates are intended to be cut from CFRP (carbon fiber sheet) 1.5mm thick sheets.

Specifications:

  • External dimensions are 218 x176 x43mm, with 213mm motor to motor, for 5” propellers.
  • The body is 12mm high, and its external wall is 3mm thick.
  • The motors guards are 4mm thick, the motors mounts are tilted 12° forward and are 4mm thick.
  • The FPV camera is tilted 13° upward, and the camera lens guard is 2.5mm thick.
  • The Rx antennas are tilted 25° on each sides of the camera lens guard, which leaves 35mm clearance across the width for an external camera (Mobius for instance) on the top.
  • Accept battery up to 108mm long and 37mm wide, with suitable battery holder.
  • The battery holder is fixed on the middle plate using five oblong lugs.
  • The Mobius holder is fixed on top of the top plate, it protects the lens with a 2.5mm guard.
  • VTx channel setting is reachable from underneath with the frame closed.
  • USB ports from FC and OSD are both reachable from the left side with the frame closed.
  • FC's alarm buzzer mount leads the sound directly outside from the right side.
  • Three serial LEDs controlled by the FC are integrated in each arm for higher visibility.

Building

All printed parts come from Shapeways (printed in white, painted in mat red with spray paint), and the carbon plates are machined from a local business.

The spacer:

The complete frame (spacer, carbon plates, battery mount, strap & pad, antennas, every screws), without electronics:

A motor and its ESC (my soldering iron isn't powerful enough to unsolder correctly the wires on the ESC, I got to be creative). With the three serial LEDs on the arm:

All the electronics connected, views from the top (the OSD part of the PDB isn't working, faulty board, so I stuck a temporary micro minimOSD):

Right now, the first tests are made with Betaflight 2.5.3 Luxfloat 2khz, and BlHeli-MultiShot 14.4.02.
