CeeGee,
The Futaba 9C system comes with an 8-channel receiver and has a built in program for using two elevator servos. With this feature you don't have to worry about any mixing switches being in the correct position before you take off.

The elevator servos are plugged into channels 2 and 8 and you activate the AILEVATOR function in the menu as described on page 49 in the manual. The aileron travel inside the AILEVATOR menu should be set to 0%. If you don't set them to 0% the elevators will work like those elevators on full size jet fighters.

I used to use splitter/reverser cables but I found that the elevators became misaligned after the plane sat in the sun for awhile. There is a screwdriver adjustment on the reverser to realign them but taking the wing off to do it was a real inconvenience. Also, I was uncomfortable after hearing that when a reverser fails that one elevator goes to extreme deflection.

Some time ago Servocity.com (a good company to keep an eye on for specials) was selling Futaba R148DF receivers two for $99.99 and I bought four so I could get rid of reversers in my other planes.
