Pirx Seven – The ultimate custom 7-inch FPV frame, part 1

Do you know this old saying "If you want something done right, do it yourself"? I do and sometimes I just live according to it. Not always, I'm not crazy, but at least from time to time!

I fly 7-inch FPV drones a lot. To be honest, they are my favorite flying devices. There are a few good 7-inch frames, like TBS Source One for example. There is a difference between good and great tho. I do think that Source One is a good frame, there are a lot of things on it that do not make me very happy tho! The list might not be very long, but it is relevant:

  • props in the view
  • limited space to install split-like hybrid cameras
  • no very convinient place to install VTX
  • it's not that big inside as one might imagine…

Because of that, and because I think I know how to do it (I'm an engineer) I've devided to design and manufacture my of 7-inch FPV drone frame that would fix what I do not like in Source One.

This is how Pirx Seven was born!

  • Dead Cat configuration
  • Plenty of space inside for everything you want! There is even a place in the back to fit the whole 30x30mm stack!
  • Place for Split-like hybrid camera in the front
  • Attachable mounts for antennas, GPS and other accessories
  • Clear, unobstructed view for HD camera like GoPro on the front deck

So far, I was able to mill a prototype unit to test it in flight. So far so good, I really have to say that I like what I designed.

What next? Test flight and some changes. The full list consists of 12 points in total and basically means that I will have to redesign almost everything…

If you want to know why the name and what does Pirx stands for, here is the answer. It's a tribute to Polish writer Stanisław Lem and his book Tales of Pirx the Pilot.

  1. uh, WOW!!! My first quad was a Lumenier QAV 250, but wanted more room for cameras and GPS, so i went over to the Source One (’cause of YOU). i do like the larger format frames, myself.
    i’m flying both at the moment, but the Pirix looks like what i’ve been looking for, so, get busy so i can hopefully pick one of these puppies up in the not-to-distant future.
    thanks for all the work that you do –
