Servo Reverser ?
Why spend $40.00 for a reverser, when you can put servo arms on opposite sides.
Question #2 Can I splice 2 6" extensions to make up a short Y harness ?

RE: Servo Reverser ?
In order to avoid a servo reverser on dual elevators, I've been known to put the control horn on the underside of the left elevator and the topside of the right elevator. The servos (located in the fuselage sides) are then driven from a standard "Y" cable. The servos are at different heights in the fuselage (left servo is lower in order to line up with its control horn right servo is higher to line up with its control horn). Both elevator halves move exactly together.

RE: Servo Reverser ?
A reverser is needed to have both halves move the same, with the servos mounted with the axis of rotation aligned with the elevators. (usual back of the fuselage installation.)
A reverser isn't needed if the servos can be mounted with the axis of rotation 90 degrees different from the elevators.
Then, using opposite sides for the horns will work. (mounted forward in the cabin, typically.)

Not quit[:@] you want to reverses the direction not the polarity of the electronics. Lots of smoke
You have to switch the wires on the pot and the motor to get it to work.

Yep, the servo plug has 3-wires: battery positive, battery negative, and signal. If those get switched around it won't work at all.
I've never opened one up to switch it inside but I know it can be done. Better be confident in soldering though. A bad joint could end up causing a crash.

RE: Servo Reverser ?
Yes The servo can be reversed, open up the servo by removing the screws holding it together and remove the bottom, if the motor is soldered directly to the board(surface mount no wiring) close it back up, if it has wires as shown, First photo you would swap the Purple/Brown wires(pot wires), and ASLO swap the motor wires Blue/Green(motor wires) photo 2. The colour of the wiring may be different but you just swap the same wires.
