The AeroPerfect™ Digital Control Throw Meter makes setting your elevator control throws a breeze! In the following example, a left elevator half is setup for +/- 9.55 degrees. If your aircraft's control throws are specified in inches or millimeters, these numbers are easily converted to degrees here. Also, the new AeroPerfect™ MU-9000X USB has a built in utility for converting from inches to millimeters!

Make sure your aircraft is held so it can't move around. You can make your own cradle or there are a number of commercially available cradles you can use. Adjust your aircraft's position so the elevator(s)are reasonably level (eyeball is fine).
Step 1:
Adjust your elevator linkages as you normally would. Move the elevator to its neutral position. You can either employ a method of mechanically clamping the elevator at neutral or use your radio and servo to hold it in position.
Step 2:
Either hand hold or clamp your AeroPerfect™ Digital Control Throw Meter to the elevator so that the edge of the measuring plate is near the hinge line and parallel to it. It is best to make your measurement as close to the fuselage as is practical. Place your AP3 Digital Display where you can view it while you make control throw adjustments. (In order to get the AeroPerfect™ AP3 into the photo, it is clamped to a music stand, but you can place it anywhere within a 6 foot radius from the MU-1800-I for easy viewing!) Simply push the RESET button on the AP3 Digital Display to set a zero reference angle.
Step 3:
Pull your radio's stick fully toward you and then fully away from you while using your AeroPerfect™ to measure the control throw angles. Obtain the desired control throw angles either by adjusting your radio's EPA's, or mechanically adjusting your linkages. If you plan to program Hitec Digital Servos to obtain your control throws, please see the Hitec Digital Servo Programming Page.
(Optional Step 4)
Since it "remembers" the zero from the first elevator half, matching elevator halves is easy with the AeroPerfect™ ! Being careful to not disturb the position of your aircraft, simply hand hold or clamp the MU-1800-I to the other elevator half and adjust your linkages until the AP3 reads zero. (Make sure you orient the MU-1800-I in the same direction as with the first elevator half- in other words, don't rotate the MU-1800-I 180 degrees with respect to the hinge line). Repeat step 3.
HAPPY FLYING!
