* Items 23335c01's weight and appearance in set 8539 seems to indicate that it is both controller and battery lid, yet under 'Item Consists Of' it indicates N/A. Also item 23335 (the lid) states it fits item 23335c01, but if 23335c01 already has a lid fitted, it wouldn't fit another. Therefore I submit 23335co2, as the controller without lid. Numbers may need to be swapped around to make sense.
