5  General Section 
Section 1: Using this manual 
This Manual is divided into three specific sections: 
Airplane, Sailplane and Helicopter.  
In this manual you will find the specifications for the 
radio and its various components and accessories. In 
addition, guidelines for the installation have been 
included. Instructions for setting all the functions and 
programs are presented in the three sections of the 
manual: Airplane, Sailplane and Helicopter. These 
features are discussed in the same order that they 
would normally be needed to set up a typical aircraft, 6 
servo winged sailplane and helicopter respectively. An 
explanation of the use and purpose of each feature is 
provided, followed by a labeled illustration of its 
respective LCD display. 
A blank data sheet has been included at the end of 
each section. Once all data has been input for a 
particular model, it is highly recommended that you 
record it on a copy of the sheet provided.  
 
Section 2: Features 
The computer-designed, ergonomically-styled 
transmitter case ensures a comfortable fit in your 
hands. You will also be introduced to our exclusive 
“Rolling Selector” on the face of the transmitter for fast 
and effortless movement through any programming 
sequence.  
The ultra-precision control sticks offer adjustable spring 
tensions and length. The throttle stick offers a ratchet in 
Airplane/Sailplane configuration. Stick modes 1-4 are 
menu selectable. 
30-model memory storage allows programming of all 
parameters of thirty separate airplanes, sailplanes or 
helicopters; you can program more than one setup for a 
single aircraft, allowing you to instantly change the flight 
characteristics. 
 
R770 Receiver 
R770 (Basic Air and Sailplane 
Systems) 
The R770 is a high-performance 7 channel PCM single-
conversion receiver with 10KHz super narrow band 
ABC&W circuitry. 
A narrow band ceramic filter for high-signal selectivity 
assists in rejecting cross modulations from other 
common radio frequencies, such as RC transmitters or 
local paging systems. 
This receiver features Direct Servo Control (DSC) for 
control of servos without radio frequency output. 
The receiver has low current consumption. 
The R770’s Slimline design allows it to fit into most 
model applications. 
R900 Receiver 
R900 (Advanced Air, Basic & Advanced 
Helicopter Systems) 
The R900 is a high-performance 9 channel PCM single-
conversion receiver with 10KHz super narrow band 
ABC&W circuitry. 
A narrow band ceramic filter for high-signal selectivity 
assists in rejecting cross modulations from other 
common radio frequencies, such as RC transmitters or 
local paging systems. 
This receiver features Direct Servo Control (DSC) for 
control of servos without radio frequency output. 
The receiver has low current consumption. 
The R900’s credit card size design allows it to fit into 
most model applications.
