RE: ZIROLI F9F PANTHER BUILD
Bob,
My view; as long as it's scale, I like it.
===========================
Assembly (cont)
I made four 33" extensions for the flaps and ailerons that go from the receiver to the inner wing.
The aileron and flap and servos were finished on the left wing.
I had to make the short brake line to one wheel the same length as the longer air line to the other wheel so both brakes released properly as one would release but the other did not completely release.
I burned out the brake servo due to improper set up of the slave to the master mixing.
(see below for details)

Four 33" servo extensions made up.
pic 2:
Colored tape from home depot to easily identify which extensions connect to each other.
pic 3:
One brake line made longer (into a loop) to match the length of the other brake line.
pic 4:
Didn't want to remove the servo so I drilled a hole in the rib so I could use a screw driver to remove the servo screw for adjustments.

Left wing done.

How I got the brakes to work on down elevator on a JR X9303 2.4
pic 7:
Select MIX 1 and put in ELEV>AUX 3 (right side lever: could also select aux 4)
Then change the graph to have a straight line left of the x-axis and 'normal' to the right of the x-axis. This slaves the aux 3 to the elevator and only moves aux 3 on the 'down' movement of the elevator.
pic 8:
Then select SW SELECT and turn on MIX (MIX is the top right toggle on the transmitter).
This allows the above aux 3 to move when the MIX toggle is moved up (down is off).
pic 9:
Next, select TRAVEL ADJUSTMENT and select AUX 3 and put in 0 for left column and 150 for right column.
This is an important last step (without this, my servo burned up trying to move the brake valve when it was already at max movement).
When you move aux 3 (right side lever), the zero on the left side will not force the servo arm past the brake valve limit. If you want the brakes to be on, say when starting the turbine without having to hold 'down' elevator, then move aux 3 to the 'on' position.
It took me about an hour of 'fiddling' to finally figure out how not to burn up the servo.
