This dual input, dual output mixer is designed for people who want to fly their coaxial helicopters without the all-in-one mixer boards that come with the helicopters. It allows brushless upgrades and is much smoother than using a VTail mixer.

The coaxial mixer input signals are the main throttle and tail (yaw). It internally mixes the two signals together to produce two main motor outputs. The motor outputs will vary slightly between each other based on the tail signal. Using this mixer, a seperate gyro, receiver, and two speed controllers (any brand) can now replace the existing electronics.

The Potentiometer (adjustable resistor) on the mixer adjusts the sensitivity of the tail.
