Zappy 100 the original

Tweaked by Denovich, adding tangs for canopy/battery mount.

This is the original Zappy 100 version, with 4-hole motor mounts. The later V5 version is the same but with 2-hole motor mounts.

Quick specs:
Weight: 5.4gm
Size: 100mm
Motor mount spacing: 9mm
ESC/FC hole spacing: 20mm
Motors: 1103/1104/1105/1106
Max prop size: approx 69mm (2.71")
Arm width: 2.6mm
Frame thickness: 3mm

Excellent and fast, lightweight 100mm frame with narrow arms for minimal wind resistance. Very quick and agile when built light using 1104/1105 motors, 300mAh 2S 45-90C Nano-tech battery, and a lightweight 6A 20x20mm esc. Recommended props in no particular order are RX2535, Racerstar Pro 2435, DYS 2435, 3020's cut down. 2 blade versions of the 4-blade props work well too.

Because the frame is so light at 5.4gm, it can accommodate a lot of different drive trains and still fly really well.

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.
