Porta-Quad (6″)

Annotated Pixhawk Version

 Autonomous Porta-Quad Frame for 6″ Propellers 

The most compact, full featured folding quadcopter yet…

This quadcopter is designed to carry all the equipment needed for fully autonomous GPS guided FPV flight.  It folds and fits into the smallest waterproof Pelican 1120 case, which measures 7.5″ x 5″ x 3.3″ (18.9 x 12.6 x 8.5 cm).  Yet the Porta-Quad 2 is capable of running 6″ propellers and four powerful 1960KV-2300KV motors totalling over 2000 grams of thrust–the total weight of Porta-Quad 2 fully loaded with FPV camera, Pixhawk, 3DR radio, GPS and long range 2200mAh 3S battery is 750 grams.

  • Comes with all hardware to build the frame.
  • $95 NOW $85 (plus $15 worldwide shipping)
  • Prices in US Dollars


Check out this user-posted video on the RCGroups Mini-Quad page.

Intro video below:

The Porta-Quad is made of super tough G10 material (3mm for main frame and arms, 1.5mm for mid-plate and bottom-plate).  The frame kit includes all hardware and 4 rubber vibration isolation bumpers.

This frame kit is easy to build into a standard FPV quadcopter, with plenty of room for everything.  To build the fully autonomous version, experience with mini quadcopters is recommended as it requires some planning to get everything into the compact frame.  Once assembled, it flies like a dream and is ready for any adventure.

The photos below shows the top layer with motors and ESCs assembled.

For a bit of history of how this design came about, see the Porta-Quad 1 page.  I used Autocad Inventor to optimise the overlapping arm design, then built a series of balsa models prior to making the first prototype G10 frames. (Animated Gif below–wait for it…)

Note: final product has larger base plate than shown in these photos.
