ABOUT RVOSD5
First Person Viewing (FPV) is an
exciting offshoot of a 60+ year old
hobby, which enables a pilot of a radio-
controlled plane to immerse themselves
in flying by watching the video from an
onboard camera.
What is FPV Flying?
Several recent technological advances
have enabled this: small cameras,
lightweight wireless video links and
high-resolution head-mounted displays.
The RVOSD5 makes FPV safer and
more fun. It features an on screen
telemetry display, full autopilot and
power management. The RVOSD5 also
acts as a ‘motherboard’ for your FPV
gear. Everything connects to the
RVOSD: GPS, IR sensors, camera,
video transmitter, main flight battery,
auxiliary battery, R/C receiver and flight
control servos.

SYSTEM DESCRIPTION
The RVOSD5 provides the pilot with
real-time navigation and aircraft system
information. The information is
superimposed over a video source and
broadcast back down to the r/c pilot via
a video transmitter/receiver system; this
is called On Screed Display (OSD).
RVOSD5 Overview
Figure 5-1 On Screen display
The RVOSD5 can also stabilize and
autonomously fly the aircraft with the
use of an onboard Inertial Measurement
Unit (IMU) stabilization system to
determine the orientation of the model
plane. The RVOSD autopilot and
artificial horizon displayed on the OSD is
dependent on the IMU.

Flight Modes
This autopilot mode will
engage automatically
when R/C link lost is
detected, and will fly the
model back to the
takeoff spot.
Level flight
The autopilot will keep
the attitude of the model
leveled on the pitch and
roll axes.
Heading hold
The autopilot will keep
the heading of the plane
at the moment this of
activation; it will also try
to keep the actual
altitude.
Position hold
The autopilot will fly
figure eight patterns
around the GPS
coordinates at the
moment of activation; it
will also try to keep the
actual altitude.
Fly-by-wire
The control of the plane
is given up to the OSD
computer. It will check
for user stick movements
and will translate to
model desired attitudes.
Control sticks are
interpreted from 0 to full
as 0-60° on each axis.
