Servo Tester
 
Test up to 3 servos.

INSTRUCTIONS:
You may find the Maxford USA servo tester is one of the easiest-to-use RC setup tools you own, as follows:

  1. Connect your 4 cell (4.8V) or 5 cell (6V) NiCd or NiMH receiver battery to any of the four sets of connectors at the end of the servo tester.
    (If you hold the servo tester with its switch on top, connect the battery so its negative/black lead is at the bottom of the servo  tester.)
  2. Connect your choice of one to three servos to the servo tester's remaining connectors.
    (If you hold the servo tester with its switch on top, connect each servo so its negative/black lead is at the bottom of the servo tester.)
Press the button on the servo tester's switch to change between the servo tester's three modes of operation:
1) The servo tester will CENTER the servo(s)
2) The servo tester will CYCLE the servo(s)
3) The knob at the end of the servo tester will allow you to MANUALLY control the servo(s)

The Industry Standard for 'servo center' is a nominal pulse width of 1.5 milli-Seconds (i.e., when the servo tester’s and/or your radio’s ‘signal-line’ pulse width is 1.5 mSec wide, the servo ‘should’ be centered).

However, since we don’t live in an ‘ideal world,’ the actual 'servo center' has an range of plus/minus a few degrees. This is due to servo tester and radio system production tolerances, the settings of any optional user controls, and the margin of error that may occur during servo manufacturing and/or calibration.

Recognizing and accepting these unavoidable variables, we recommend using the tester during assembly, but it is important to also build-in a 'fudge factor' to ‘fine-tune’ all linkages after assembly is completed and the radio receiver is installed.

The servo tester is a great tool for initial setup; however, at the end of the day, you will want to use your transmitter to define each airplane’s actual 'servo center' – then to perform any necessary fine-tuning of your radio’s adjustments and your airplane’s mechanical linkages.
