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.

NOTE: This servo is not recommended for use with receiver/voltage regulator combo's. We highly recommend you use the ProTek R/C Dual Power Bus Advanced Linear Voltage Regulator, or similar regulator to avoid potential brown out conditions. Also, this servo can be used with the Microbeast FBL controller without issue, but VBar, Ikon and other FBL controllers may require the use of a voltage regulator.
