With the JR you can reverse the three servo chanels and the three
functions that drive the servos, pitch, ail, and elev.
First ch3 needs to be on the servo that is at 12:00 or 6:00.
ch 2 and 6 are on the sides (4 and 8 or 10 and 2).
Move the throttle stick and see that all three servos are moving.
It doesn't matter if they are moving in the right direction.
If all three servos are moving on the collective input the tx is
in CCPM mode and the servos are on the correct ch at the
Next make a 3 X 3 table and fill in how the servo moves when
commanded by the tx. Label the columns with the ch and the rows
with the function. R= servo moving wrong way N= normal
ch6 ch3 ch2
pitch R R N
ail N - R
elev N N R
This is how one of my helis came out.
Now the trick is to set the servo and funtion reverses to make
all the servos work in the correct direction. In ths case I
reversed the pitch function and then reversed ch2.
Hope this helps
