You can get a bellcrank from Central Hobbies. You can use a single servo and install the bellcrank.

You can use an Equalizer. It is essentially the same thing as a JR Matchbox- but about $20 cheaper. It allows you to reverse one servo and individually adjust the neutral and endpoints of both servos.

Please don't use a reversing Y-harness. They don't work. You will always get differential throws with a reverser. You can use one if you don't need precision elevator throws, but if you want to fly precision or any competition- forget it.

There's a few options to get you started.
