This is a 120mm version of the Zappy 100, with 2-hole motor mounts and lugs for rubber bands, designed for a 16x16mm esc/FC.

Quick specs:
Weight: 5.9gm
Size: 120mm
Motor mount spacing: 9mm
ESC/FC hole spacing: 16x16mm
Motors: 1103/1104/1105/1106
Max prop size: 84mm (3.3")
Arm width: 2.6mm
Frame thickness: 3mm
Motor center hole diameter: 3mm - refer "additional notes" below.

Fast, very lightweight 120mm frame with super narrow arms for minimal wind resistance and thrust blockage. Very quick and agile when built light using 1104/1105/1106 motors, 300mAh 2S 45-90C Nano-tech battery, and a lightweight esc.

Build pic:

This "true x" frame is cut so that the grain of the carbon fibre sheeting runs down the length of the arms, rather than the conventional layout which has the grain running at a 45 degree angle. This dramatically increases the strength of these super-thin-arm frames, and requires a different, less efficient layout for AP to cut the frame, and thus is more costly. We consider our frames to be premium and cutting-edge, and that the extra cost of these unconventional frames is justified.

The motor center holes may be too small for some motors and might require countersinking, or drilling to a larger size, just enough to relieve any binding. Please check the circlip is not binding as the motor is rotated by hand. This is done to maximise the frame strength in this area.
