Hyperion RDU & LDU Phase Tachometer (Compatible with Mikado Vbar Governor)

Hyperion RDU & LDU Phase Tachometer!
The Best tachometerto work with Mikado Vbar Governor!
Just attach inline on one of the three brushless motor wires (solder up a male/female connector adapter for convenience)
and log motor rpm extremely accurately throughout the motor run.
You need to know how many magnets are in your motor to configure the RDU & LDU,
but even if you don't know the Emeter can be connected and RDU rpm compared with the Emeter tach.
Makes it a snap to set it up right, every time... And this unit is NOT plagued by the problems found in some other brands. It's rock solid!
