RAY R-12B...R-70SB
Programmable Electronic Controllers for Brushless Motors
Congratulation on your purchase of a RAY Line electronic controller for brushless motors. The
state-of-the-art RAY Line covers almost the entire range of electric powered planes flown by a
Sunday flyer. All the ESCs can be quickly programmed using you transmitter and even easier
with the optional RAY Card.
PROGRAMMABLE FUNCTIONS
1. Programmable Brake Setting (use the brake on for folding props applications only).
2. Programmable Battery Type (LiPo or NiCd/NiMH).
3. Programmable Low Voltage Cut-Off Setting.
4. Programmable Factory Default Setup Restore.
5. Programmable Timing Settings (to enhance ESC efficiency and smoothness).
6. Programmable Soft Acceleration Start Ups (for gearbox and helicopter applications).
7. Programmable Governor Mode (for helicopter applications).
8. Programmable Motor Rotation (clockwise/counterclockwise).
9. Switching Frequency.
10. Programmable Low Voltage Cut-Off Type (power reduction or immediate shut down).

CONNECTING THE RAY ESC
The speed controller can be connected to the motor by soldering directly or with high
quality connectors. Always use new connectors, which should be soldered carefully to the
cables and insulated with heat shrink tube.
Use only high quality connectors to connect the ESC to the flight pack as well - 2 mm gold
plated connectors (Pelikan Daniel #7939 or #7940) for currents up to 20A; 3,5 mm (#7941),
4 mm (#7946) gold plated connectors or DEAN-T (#7949) for currents up to 70A and 6 mm
(#7945). The maximum length of the battery pack wires should be within 15 cm (6 inches).
Plug the UNI servo connector cable of the ESC to your receiver throttle output. The ESCs
featuring BEC or SBEC (50 and 70 A ESC only) voltage stabilizer will feed your receiver and
servos from the flight battery pack.
