tweaky 120

The original tweaky design, "tweaked" by Brainstorm, and Denovich.

Specs:
Weight: 9.2gm
Size: 120mm
Frame thickness: 3mm
ESC/FC hole spacing: 20x20mm
ESC/FC hole size: 2mm
Motors: 1103/1104/1105/1106/1304/BH1402/RX1404
Motor mount spacing: 9mm
Motor mount hole size: 2mm
Motor center hole - 4mm, refer "additional info" below.
Max prop size: 83mm (3.27")
Arm width: 4mm
Arm thickness: 3mm

Build with Realacc D1106 6000Kv motors, DYS3045 props and 300mAh 2S Nano-tech battery.

Build with RotorX 1404 motors, DYS3045 or RX3044 props, and 450mAh 3S Nano-tech battery.

At the other end of the scale, the frame could be built with  BR1102, BR1103B, or low Kv 1104 motors as an indestructable trainer, or just a general purpose recreational quad with long flight time.

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.
