This is probably the most powerful servo applicable to our
giant-scale RC application. Everything of this servo is
about high power, mega-size application. For example,
servo casing is made out of light weight die-cast aluminum;
case assembly is water resistant, double large-diameter ball
bearing support, dedicated power input for high torque
generation; large output shaft for reliable high torque
transfer. Tonegawa Seiko's superior design has earned it
worldwide licenses and being used in various avionics and
For our purpose of usage PS050 is an ideal choice when it
comes to multi-servo rudder application in 40% scale or
- It generates enough torque to out perform four JR 8611A.
- One PS050 weighs only a bit more than two JR8611A
- Big $$ saving; four JR8611A would cost you about $460
Like many other servos of similar design, PS050 develops
more speed and power in proportion to its input voltage.
Granted Tonegawa Seiko rates PS050 up to 8.4Vdc on input, we
have seen many successful cases where users bumped input
supply to 12Vdc to obtain a monstrous 1,800 oz. in. of
output torque. A word of caution for this type of non-
standard practice. As more current is pumped into the
servo motor, motor coil will also heat up quick which may
result in inaccuraccy in positioning, or in the worst case
motor failure. Proper cooling of the servo electronics
(ie. cooling vents in servo casing) must be considered
before attempt such operation. Although these are some
actual examples of such application for PS050, AirWild in no
way endorses or approves such 'outside the specifications'
practice. This may also void all manufacturer warranty.
Following is some common power configurations for PS050:
