This will be a noise suppression capacitor across the motor, so that the motor running doesn't trash the receiver sensitivity. Not all bits have this. It might look like a bit of metal, but there is a "chip style" capacitor in there somewhere.

2nd: also on the underside, the cylinder shape thing(i'm guessing its a capacitor), on the mircosizer it says 85 C, while the bit char-g says 105 C. strange.
It's a capacitor, used in the voltage doubler circuit-- it gets you the 3v to run the rx chip. 85'c or 105'c, is just the temperature rating, don't worry about this.
