"I'm gonna name this one "Clean Sanchez" after a few crashes I will change name..." LOL nice
I got exactly the same frame off myrcmart, for 7$ ... just haven^t FPV'd it yet as i didn't have a small enough camera. Running tarot 1806, and cut off 5x4x3 to about 3.5". What props are you gonna use?
EDIT: Attached a pic just as reference, maybe it helps. You said 150, mine was described 148, i'm sure it's the same frame. I just couldn't find any 3.5" props to buy...

Showing love for the DYS! Are those 2300kv? I can do a quick thrust test on 3" tomorrow if you want.
Mount your motors upside down - this way it may fit 4". I have serious doubt that 2300kv will be any good to drive 3". I tried this on my cobras (on a full weight 5" mini) for fun and that was baaaad
but...
if you have a spare 5" frame and are able to make it all superlight (and I see you can)... those motors will be a blast on 5040x3 props and a 4s pack. Believe me, tested

If you can do a test that would be awesome. I don't think anything bigger will fit on this frame. the props are almost touching. I had 1306 3000kv before but they motors got super hot when I ran 4s.

I had rebuilt my thrust stand for this, but then I hurt my back and couldn't test. Sorry for a lame excuse, test has to wait for tomorrow....

Yeah, it's better than I thought, should be flyable on 4s.
