Actually, there is a very good reason for the backup battery. If you put a lot of draw on the 12v battery, it's voltage can drop very low. If it drops too low, the RC loses power, shuts off, and then reinitializes when it powers back up. The backup battery keeps this from happening, so even if your motors die a little, you won't have a few seconds of being dead on the field.
