Sold! Definitely a challenge, but that is part of the fun. Two cars in one because it flips over. We keep it indoors as dirt might foul it up and it is too awesome to subject it to damage. ## Frequently Bought Together - Lego Technic App-Controlled Transformation Vehicle 42140, Off Road Remote Control Car, Building Car Kit That Flips, 2in1 RC Truck and Race Car Toy, Great Gift for Boys, Girls, Kids Who Love RC Cars - LEGO Architecture London Skyline Collection 21034 Building Set Model Kit and Gift for Kids and Adults (468 pieces) - LEGO NINJAGO Ninja Ultra Combo Mech 4 in 1 Set 71765 with Toy Car, Jet Plane and Tank Toys Plus 7 Minifigures --- ## 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.co.uk/products/411947524-technic-app-controlled-transformation-vehicle-42140-off-road-remote-control](https://www.desertcart.co.uk/products/411947524-technic-app-controlled-transformation-vehicle-42140-off-road-remote-control) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
