## Questions & Answers

**Q: Y’all could take $150 off, why such a ridiculous price?**
A: One word, Lego. No, but this is a very big, nice, well detailed set, and it’s remote controlled. The motors and the wireless hub cost around $150-$200. Not saying the price is perfect, but I definitely see why it is what it is.

**Q: Why is this priced like it is made of gold ?**
A: So tightwads like you will have something to complain about. Nobody is forcing you to buy it, are they?

**Q: Difference between frustration free packaging and standard packaging**
A: Frustration free packaging means they ship the LEGO box "as is" meaning they don't put the actual box inside another box. They just put the shipping label on the actual box and that's how it is shipped. I would never choose this option because too many things can and probably will go wrong by choosing this option. You're better off doing standard packaging where the LEGO package is put inside a cardboard box and then it is shipped. Better protection...

**Q: Is there an up armored version?**
A: unfortunately this is the only version currently available.

### ⭐⭐⭐⭐⭐ One of best Lego set ever
*by J***A on 21 August 2022*

### ⭐⭐⭐⭐⭐ This is a GREAT KIT!
*by T***M on 19 October 2022*

Another home run for Lego! Instructions are superb, almost without exception. There were no missing parts, and everything fit perfectly, though when marrying some of the larger assemblies together, you have to do a little finagling, but that should be expected on any model this complex. There was a moment of trepidation when the model was complete and I started it for the first time, but amazingly it worked perfectly! Yes, it is a lot of money but when you consider the amount of engineering hours that had to go into developing this monster and it's fairly limited market, plus the number of blocks needed to build, the price is really quite reasonable. You can trust Lego parts to fit together like they should without being loose or requiring a hammer and quality like that costs extra. This is not a model for the inexperienced or young and mechanical ability is a plus. Build time was about 26 hours - give or take - because I really didn't time myself.
