Nope, there should be disk-capacitors already soldered to the tail-motor. If not solder at least 2 on, solder from the Positive (+) terminal to the outer case of the tail-motor, & from the Negitive (-) terminal to the outer case of the tail-motor, if you have a capacitor left over, you could go from positive (+) to negitive (-) as well, these eliminate motor-noise.

When you plug the battery-in wait 5 seconds, and you'll hear (beep,beep,beep) from the tail-motor (ready to arm), Push the TX stick for the tail to full RIGHT & hold, you'll hear (beep,beep,beep,beep), then go full LEFT & hold, you'll hear (beep,beep,beep). Tail-motor ESC is now ARMED, and will start ON ITS OWN, unless you hold the TX stick to full LEFT when trying to move the helicopter.
