We’re talking mixing and matching quads parts to build “FrakenQuads” on the RCGroups thread: Blade nQX FC board on mQX & Ladybird size quads
I know there lots of newbies looking to do this, but wasn’t sure of the relative sizes when we talk about mQX size or Ladybird size. We use those terms because the Blade mQX is the first on the market in that type and size. And the Walkera Ladybird was the first on the market in that relative size.
The nQX is thrown in there because the topic of the thread is to use the nQX flight controller (FC) on top of the mQX, Ladybird style frame. Plus, the nQX has a unique frame. In that the motor distances sits somewhere between the LadyBird and Hubsan X4 (aka Traxxas QR-1), yet the prop guards give it a visual silhouette of a slightly larger bird. Which I find helps me in orientation once it’s a good distance from me.
Anyways, hope that helps. I took the mm size distance between prop center. Then converted it to a pixel value. So the 155mm mQX becomes a 155px on the screen. :)
