The crystals from the radio is located on the back of the radio. You see a tap that has 72.xxx mhz on it? remove that take and you'll see the crystal. Same on the receiver.

when you sync the radio and receiver you must turn on the radio first. Then lower the left joystick down all the way and the speed trim needs to be done as well. Then connect the battery to the heli and wait 5 seconds. If sync doesn't work all ways then please remove both crystals from the radio and receiver, turn it around and re insert it.

Where are the crystals located? or what exactly is it?
