Plug and play brushless kit guaranteed to startup. CO5 with pinion and motor connector installed, paired and tested with Walkera 4G3 ESC for best timing.

You can effortlessly prolong battery life by frequently checking its voltage. Measuring 1-cell for Walkera/Novus and 3-6 cell for Trex450/600 helis, this one step plug & test meter is accurate and much easier to use than most cumbersome voltage meters.

This is a battery meter with built-in low voltage alarm can also be installed on board helicopters. At low voltages, a led will light up and the double buzzers will also sound a warning for pilots who are too far from the helicopter to prevent crashes.

This pitch scale is a wider design that measures +15 to -15 degrees Instead of the typical +12 to -12 degrees. Contrasting orange scale & deep blue pointer with a larger finger friendly low increment knob makes it easy to see and make minute adjustments.
