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. ## Frequently Bought Together - LEGO Technic App-Controlled Cat D11 Bulldozer 42131 Building Set for Adults (3,854 Pieces) - LEGO Technic John Deere 948L-II Skidder 42157 Advanced Tractor Toy Building Kit for Kids Ages 11 and Up, Gift for Kids Who Love Engineering and Heavy-Duty Farm Vehicles - LEGO Technic Peugeot 9X8 24H Le Mans Hybrid Hypercar 42156 Collectible Race Car Building Kit for Adults and Teens, 1:10 Scale Racing Car Model, Gift for Motorsport Fans --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/411963784-technic-app-controlled-cat-d11-bulldozer-42131-building-set-adults](https://www.desertcart.us/products/411963784-technic-app-controlled-cat-d11-bulldozer-42131-building-set-adults) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
