It is NOT a good idea to operate your radio for long periods with the antenna down. This causes the transmission electronics to become overworked and heated. It is best to remove the crystal so that the transmitter is actually disabled. On the Futaba 9C I simply pop the RF module from the back of the radio.
People don't remove them to save juice (an added benefit), but to prevent damage to the crystal/electronics.
Sure it'll work fine, but you are heating those components up... somewhere down the orad, pehpas wiht a plane in the air, you might experience shortened range or worse, total failure.
