Wing Wing Z-84 Pixracer Build

The Wing Wing Z-84 is a flying wing frame. It is small, rugged and just large enough to host a Pixracer.

Key information:

• Frame: Wing Wing Z-84
• Flight controller: Pixracer (Discontinued)

Parts List

Z-84 Plug n' Fly (PNF/PNP) or Kit

• Banggood

TIP

PNF (or "PNP") versions include motor, propeller and electronic speed controller. The "kit" version does not include these components, which must be purchased separately.

Electronic Speed Controller (ESC)

Any small (>=12A) ESC will do:

• Lumenier Regler 30A BLHeli_S ESC OPTO (GetFPV)

Autopilot and Essential Components

• Pixracer kit (including GPS and power module)
• FrSky D4R-II receiver or equivalent (jumpered to PPM sum output according to its manual)
• Mini telemetry set for Holybro pix32
• Digital airspeed sensor for Holybro pix32 / Pixfalcon
• 1800 mAh 2S LiPo Battery - e.g. Team Orion 1800mAh 7.4V 50C 2S1P with XT 60 plug.

Recommended spare parts

• 1 cm diameter O-ring for prop saver (Hobbyking)
• 125x110 mm propellers (Hobbyking)

Wiring

Wire the servos and motors as shown. Use the MAIN outputs (not the ones labeled with AUX). The motor controller needs to have an in-built BEC, as the autopilot is not powering the servo rail.

Port	Connection
RC IN	PPM or S.BUS / S.BUS2 input
MAIN 1	Left Aileron
MAIN 2	Right Aileron
MAIN 3	Empty
MAIN 4	Motor 1
