15 Point Matching

 

(Smart Bus All Versions)

 

15 point matching is useful for getting the best possible match between servos. This in-
cludes mechanically matched servos (aileron) or non mechanically matched (left and right 
elevator). We are now going to go through the 15 point servo matching process. For best 
results please do 3 point match before proceeding.

 

Step 1

 

From the 3 point matching screen. Press the 

Multi 

button.

 

Step 2

 

You should now see the multi point match 
screen. Similar to the 3 point match, as you 
move the transmitter stick for that channel. 
The bars will changes colour from blue to 
yellow.

 

Step 3

 

Slowly move the transmitter stick for that 
channel from one side to the other, if at any 
point you hear servo buzz. Hold the trans-
mitter stick in that position and use the 

DEC

INC 

buttons to sub trim at that point. Sub trim 

the servo until the servo buzz lessens or dis-
appears.

 

Step 4

 

Repeat step 3 for the entire range of the ser-
vo, this can be repeated as many times as you 
wish. 

 

Step 5

 

Once you are happy with the sub

-

trim press 

the 

back 

button to move back to the 3

-

point 

sub

-

trim page. Pressing back again from the 

 

3

-

point sub

-

trim page will save the trim val-

ues to memory.

 

Note: If the servo is only moving a small amount. (Example:  10

-

15 degrees each way) 

You will only be able to use a small number of bars on the 15 point match. To use more 
bars, we recommend you increase the servo range by using a smaller servo arm.

 

Note: You can return the servos sub trim 
values back to default by pressing the 

 

Reset 

button.
