My first thoughts about Land Raider were that there a lot of space to put power sourse, meters of cables, switches, resistors... But there is even less space then in a Rhino. I used the space between the intro and outro sections, but it was really not that easy as i thought. There are 3 3V Li-ion batteries for the yellow lights(4 3mm LEDs), they are hidden in the first left door of the LR, we can see the switch and the cable on the last photo. The red light (2 5mm LEDs) uses 2 3V Li-ion batteries hidden after *the machine god*. Also i used reed and a magnet, so when the assault ramp opens the red light turns on.
BTW Im from Ukraine, between Poland and Russia.
