Custom Quad Frame

Hey Aaron! The frame looks nice and the perforation holes along the extrusions make sense. You did not mention what is the size of the frame. So it is hard to tell.

On the other note, the dove tail in the middle will be a primary location of the stress concentration, especially at landing, right after you touch the ground. The bar dove tail portion on the lower bar will be subjected to a bending loading and the surface of the dove tail will be at tensile loading. Lots of take-offs and landings may result in cracks forming at the corners of the dove tail. Well, they will form for sure, just depends on number of take-off-and-landings.

Just thought I should attract your attention to that. Otherwise, I like it.

260g is a very good weight, although it is typical to weigh the central mounting plates and the PDB as part of the frame.

My frames weigh between 195g and 450g (with plates and PDB.)

Nice. a small well attached platform should take the pressure off the dovetail?
