Description:
The RX3S OrangeRx Flight Stabilizer from Pyramid Models is a 3 Axis gyro system designed to
stabilize the flight of a 4Ch Fixed Wing type Aircraft. It provides stabilization for the Aileron (roll),
Elevator (Pitch) and Rudder (Yaw) Axis. It utilizes an Atmel 168 processor and an
Invensense ITG3205 Mems 3 axis gyro chip. On the board is an Atmel AVR ISP 6 pin
type programming connection making it available for some 3rd party future upgrades or
possible upgrades from Pyramid models (No announcement of this availability or promises of
this availability to date).
The board has 3 independent gyro gain dials as well as a 3 switch Dip switch for reversing the
gyro channels.
Pre Setup:
I recommend that you fly the plane you plan to mount it on and try to achieve a mechanical setup
that yields zero or near zero subtrims as well as full servo travel (100% ATV/Travel Adjust/End-
point Adjust). Although these 2 steps are not required, they yield less problems in the end (like
driving servos to the point of binding during flight or transport while on).
