ProTek RC 270S "Greggor McGrath Team Edition - Tail" Digital Servo (High Voltage)
This is the ProTek R/C 270S "Greggor McGrath Team Edition - Tail" Digital Servo. Greggor McGrath is an incredible pilot, with a skill set that exceeds his reputation as one of the nicest guys at the field. That's why we collaborated with Greggor to develop the 270S Team Edition Tail Servo. The 270S Team Edition delivers the precision that ProTek R/C team pilots demand, combined with the quality, reliability and customer support that our customers demand from ProTek R/C.
- "When we first started developing the 270S, I asked for a fast servo. When I tested the first production sample, I was blown away by how fast it was! Even with the insane speeds, it was still smooth and precise. I got more than I asked for." - Greggor McGrath, ProTek R/C Team Pilot
The ProTek R/C 270S Greggor McGrath Team Edition Tail servo delivers lighting fast 0.035 transit speed at 6.0 and 7.4V, for instantaneous tail response. At 6.0V the 270S delivers 102 oz-in of torque, and hen you push the voltage to 7.4, the torque jumps to 127 oz-in! Spec's like these make this servo an excellent choice for any 550 to 800 class tail application that can benefit from lightning fast transit speed and precision. Plus the 760μs pulse width and 560hz frequency delivers instantaneous response. A black anodized aluminum case with gold accents provides a striking appearance that sets it apart from any other servo on the market, while at the same time providing bomb proof durability and efficient heat dissipation. Other features include a durable metal gear train supported by dual ball bearings for smooth and precise rotation, 290mm long 22awg connector wire with gold plated connectors, and a coreless motor.
Plus, instead of a cheap plastic servo horn, ProTek R/C goes the extra mile with an included aluminum double arm clamp lock 360° rotation servo horn that lets you set your sub trim mechanically from the servo horn, rather than digitally from the transmitter. Stop wasting your money on budget servos that look good in the spec list, but fall short when its time to perform. Get ProTek and don't look back.
Warning! This ProTek R/C servo requires that you use a m3x10mm screw to attach the servo horn to the output shaft. If you choose to use another screw, be sure to use a 10mm length screw. Use of a shorter screw can cause failure and will void your warranty.

Notice: ProTek R/C helicopter servos may require an isolated power source or the use of a high-amperage power regulator, like the PTK-4000.
Like many of other leading helicopter servo lines, the high torque and speed specs of ProTek R/C helicopter servos also mean that these units can generate high-frequency noise on the power lines, which can interfere with the proper operation of some flybarless systems and receivers.
We have confirmed this issue exists with the MSH Brain, iKon, newer Vbar Silverline, and the Spartan VX1 and VX1n. Our lab tests indicate older VBar units and the BeastX are far less susceptible to interference and should work well with ProTek R/C servos, even without a power regulator or isolated power source.
We strongly recommend running two separate power sources (i.e., one battery for the servos and another for the flybarless systems) as the best way to eliminate any possible interference.
An alternative approach is to use a power regulator to filter the power bus between the servos and flybarless system. In order to do so, you must run it in regulator (not bypass) mode.
As today’s servos push the limits of speed and torque specs, flybarless systems need to evolve similarly. Nevertheless, we are aggressively pursuing design changes and power isolation/regulation accessories that will broaden the compatibility of our helicopter servos, while maintaining the leading level of performance you’ve come to expect from ProTek R/C.
