Lego Excavator 8043 Mod

Made a quick mod to my 8043 this evening. It now has a pair of XL motors in the base, an additional IR receiver and battery pack! And goes like the clappers as a result! Very simple mod to do, though it does have a limitation in terms of the IR receiver has to be under the arm end of the body, otherwise the battery case and motors cover the IR receiver. I’m considering scrapping my smaller excavator and rebuilding the base on the 8043 to be a bit bigger, as the motors, while fitting nicely, are a bit exposed and therefore potentially reducing the approach angle. I’d also like to work on the CoG of the model, adding weight in the base has helped, but the battery case & motors need to slide forwards I think to properly balance the unit.
