Yep, 5mA FS is what the SX-28(A) and the AR-88(X) needs.

Providing that the movement works in reverse, however (resting on the right side when the receiver is off).

Thank you, Glenn Little  WB4UIV, for the schematic.

With my stock of tiny 1/8 watt resistors and a battery and VM, i calculate FS at 5 MA.
