Simple Transmitter Setup – Aerobatic Airplane (ACRO)

34. Servo EPA (End Point Adjustment). Now we’ll go

through and set the servo travels for each channel.

This is both helpful and important, because you can set

the throw of each servo, in each direction, so that there is

no binding. Binding is important because it causes very

high current drain, and can lead to a battery dying prematurely.

Another use for the EPA function is to adjust

the model’s total throws to match the recommended control

motions specified on the plans or instructions by

the model’s designer.

35. To set travels, get to the

EPA menu by pressing one

of the Up or Down Edit buttons

repeatedly until EPA

appears. In sequence, we’ll

set right aileron right travel, right aileron left travel, up and

down elevator travels, right and left rudder travels, open

and closed throttle positions, and left aileron travels.

36. When you reach the EPA menu, you’ll see the screen

as shown. If you select The channel 1 (numeral 1 will be flash-

ing)

right aileron, the percent symbol will be flashing, and

you’ll notice that you can change the L/U indicator to R/D

(or vice versa) by moving the aileron (right) stick. You are

about to see that this is how you set the travel directions

independently for each stick motion.

37. To set the RIGHT aileron motion, move the aileron

stick all the way to the right and hold it. The letters “R/D”

should appear next to the flashing percent sign, meaning

you are setting either Right or Down travel (with ailerons

it’s right or left only, but the display is set up to use the

same indicators for elevator and throttle, thus the dual

meanings for the letters). Now if your servo is stalled or

binding, you’ll hear a buzzing sound. Hit the minus

-Decrease Data key until the buzzing stops. If the servo

is not buzzing, leave the setting at 100%. If you can,

choose a location for the pushrod on the servo arm so

that the throw is adjusted in the 90-100% range.

38. To set the right aileron’s LEFT motion, move the

aileron stick all the way to the left and hold it. The letters

“L/U” should appear next to the flashing percent sign

. Again listen and hit the

-Decrease Data key until the buzzing stops. If the servo

is not buzzing, leave the setting at 100%. (Remember,

you’re only setting the right aileron travel. You set the

other aileron’s travel in channel 6’s EPA.)

39. To set the UP elevator

motion, press on the Right

Cursor key until the

channel 2 will flashing.

Now move the right stick all

the way to the transmitter bot-

tom and hold it.

The letters “L/U” should appear next to the flashing

percent sign. Again listen for a buzzing sound to indicate

the servo is stalling, and hit the -Decrease Data key until

the buzzing stops.

If the servo is not buzzing, leave the setting at 100%.

40. Repeat the previous step for DOWN elevator by

moving the stick all the way to the top of the transmitter,

full “down” elevator. Check for binding and adjust the

percentage as before.

41. To set the throttle position at IDLE, first return to the

regular display and set the throttle trim to -25%. Then

go back to the EPA menu and press the Right Cursor

key until the channel number 3 will be flashing. Now

move the throttle stick all the way to the transmitter bottom

and hold it. The letters “L/U” should appear next to

the flashing percent sign. Listen for a buzzing sound to

indicate servo stalling, and hit the -Decrease Data key

until the buzzing stops. Change the setting to nearly but

not completely - close the throttle (engine idle).

Later you may increase or decrease this number so you

can’t accidentally shut off the engine using the trim tab.

42. To set the FULL throttle position, move the throttle

stick all the way to the transmitter top and hold it. The

letters “R/D” should appear next to the flashing percent

sign. [Notice that the Eclipse 7 Pro transmitter thinks of throttle

stick positions to the reverse of the way it seems, in

that with the throttle stick fully forwards - “up” towards the

transmitter top, is the Down position.] Listen for a buzzing

sound to indicate the servo is stalling, and hit the

-Decrease Data key until the buzzing stops. If the servo

is not buzzing, leave the setting at 100% or change your

linkage as necessary to fully open the throttle.

43. To set the RIGHT rudder motion, press the Right

Cursor key until the channel 4 will be flashing.

Now move the left stick all the way to the transmitter

right and hold it. The letters “R/D” should appear next

to the flashing percent sign. Listen for a buzzing sound

to indicate the rudder servo is stalling, and hit the Data

-Decrease key until the buzzing stops. If the servo is not

buzzing, leave the setting at 100%. You may wish to

increase or decrease this number depending on how

strongly the model reacts when the rudder is deflected.

Now move the stick to the left side, and repeat the setting

procedure for left rudder.

44. In the same manner as described above, be sure to

set EPA values for channels 5 (landing gear) and 6

(second aileron), if you have either.

45. If you wish to have the

flaps operate with the CH6

knob, go back to the FLPT

menu and input a number

greater than zero. Adjust

the number to get the

desired amount of flap travel as you turn the knob.

46. If you wish to have differential aileron travel, this can

be done in the flaperon menu. First, we’ll reduce the

down travel on the right aileron. Press the Right Cursor

key until the channel numeral 1 and MAS will flashing

Hold the aileron stick to the left and press the

-Decrease Data key until the number is smaller. 50-75%

is a good starting point. Watch to be sure you’re setting

the down travel on the right aileron.

47. Next, we’ll reduce the down travel on the left aileron.

Press the Right Cursor key until the channel numeral 1 and

SLV will flashing
