You can't go wrong with the Turnigy 9x transmitter. It's got more functions than you can shake a stick at and you can even upgrade the firmware. So many people that fly multicopters are using these: http://www.hobbyking.com/hobbyking/s...976&aff=114030
I don't see any mention of the flight controller, but obviously you will need one of those. This is a really good one for beginners: http://www.hobbyking.com/hobbyking/s...723&aff=114030
The Turnigy 3s 2200mAh lipo should be great for your setup and give you plenty of flight time, buy lots of these: http://www.hobbyking.com/hobbyking/s...636&aff=114030
The RCTimer ESCs that come pre-flashed with the SimonK firmware are great, you'll need 3 of these: http://www.rctimer.com/index.php?gOo...9&productname=
You will also need some sort of power distribution board and a few other bits and pieces like a servo to control the tail motor.
