Moon CopterG 10

This one is fairly simple.

From the Rules Sheet:

Light the Whirlybird on the right ramp, then load it with high explosive bombs by locking balls into the Moon Copter. Three balls and the Whirlybird takes off for low-altitude urban warfare, ready to bomb thugs back to the stone age in Whirlybird Multiball.

On the right half of the table you can see a watch/clock face in front of a ramp/orbit that looks sort of like sewer grating or bars. Hit the ball up this ramp until the Whirlyball on the blue/green sign above the ramp is lit up. There are four items on this sign, so it will take four shots with one ball. The lights seem to go back a place if you lose a ball.

Once you have Whirlybird lit, continue shooting the ramp to lock three balls. After you've locked the first ball, you can lose a ball and still lock more without having to light the sign again.

When you lock three balls Whirlybird Multiball starts and the achievement unlocks.
This is how I unlocked it on the 360 version.
