The top and bottom halves of the bus can come in either yellow or red, resulting in 4 different color combos available. As you may have noticed, I had to cut the demo short (I usually let it go for around one minute) because the chip was having power issues and I didn't want to fry it. These old chinafake buses with lots of complex mechanical stuff going on barely have enough power to sustain themselves (hence the 6 AAs needed), and with age and the many split gear replacements I had to do (some of which didn't fit perfectly) this thing is barely hanging on. If the necessary parts become available and I am able to fully fix this thing, I will very likely do a remake of this video (believe me, it was a LOT worse when I first got it). Little tidbit about the batteries it takes, the batteries are hooked up in parallel (3 one way, then 3 the other way), not in series like the box says. I can only imagine how many battery explosions occurred because of that. The battery compartment is only big enough for 6 R6Ps, so you can only fit 5 regular li-ion batteries in there (I have a whole video about that, it's titled something COOL and ATTENTION-GRABBING like "The Chinafake Battery Conspiracy"). Thankfully because the batteries are in parallel, it still runs if you do that (in theory it could run fine off of 2 AAs, but it does not (see: power problems). If another one of these pops up, I will likely get it - I think these are really cool and perhaps that one won't have as many issues.
