Servo Reverser

I designed this circuit to help with split elevator and dual flap installations, when one servo needs to be reversed to get both control surfaces operating in the same direction. Using this circuit may be simpler than programming a mix into your transmitter (if that is even possible), and it uses one less channel!

Features

• High Accuracy (±1uS Resolution)
• Normal and Reversed outputs (no Y cable required!)
• Sub-Trim adjustment on Reversed output
• Glitch Filtering (ignores pulses that are too short or too long)
