I believe O3 unlocks the freestyle potential of 3-4" quads but I've long been troubled by other O3 freestyle platforms overly long ass aka fuselage. Damn DJI for gigantic VTXs, or damn us for lack of space management?

Entering Hot Hatch: One simple trick of drilling two more sets of mounting holes front and back (see them in pic 2), now we have a frame that can comfortably swallow most 5" mini stacks (you can put the aikon 50A in it, not the Foxeer Reaper 66A though) and a O3 Air Unit, without its ass poking out (Pic 5).

Coming in at 70g with 4mm arms and a 172mm large wheelbase, it can fit 3.5-4" props with no props in view. It strikes a good balance of weight, durability, components compatibility, and maybe coolness.

Bonus points: the hatch design from Ummagawd Remix V2 simplifies maintenance (gotta pay homage to my favorite frame of all time), and the core locking mechanism inspired by Ryan Harrell's QAVS-V2 stiffens the frame while making arm swap a breeze.

Recognize the plaided seat? You already know what it is.
