Also, since the Tone is extremely strong, you will need a Alu or Carbon RC Tray.
You will ALSO need a seperate battery pack for powering the Servo.
a 3s Lipo is fine.
It doesn't need it's own battery, providing your running a decent Rx pack (ie, 6V 3000mah)
All it needs is an extra feed from the Rx Battery, or (as I did) make up a lead that has the Rx supply and an extra wire for the servo supply.
