How do you wind up a sabotage droid on Star Wars republic heroes

For the Wii version of the game, jump onto the sabotage droid and stab your lightsaber into it. Then shake the Wii remote back and forth quickly and repeatedly. When the droid is fully charged, the character you're playing will automatically jump off. And be sure to check where your aim is on the screen so that the droid will go in that direction once it is fully charged
