Excellent product, superb delivery and packaging. Recipient absolutely overjoyed with the truck and all its excellent parts and performance

i have to say radio- controlled uk are spot on with the service provided and fast delivery, their products are packaged with great care i ordered a Rlaarlo AM-D12 1/12 RTR Brushless RC Desert Car and it arrived 48 hours later, and boy what a great little buggy for the price so well done radio- controlled uk . Oliver who owns the company was very polite/honest and helpful in answering my questions, and nothing seemed to be to much trouble i will buy from this company again. Good service, helpful staff, always replies to a message right away 10/10 stars from me regards Ian

Not ran it yet, but the build quality is excellent. Excellent service and communications from radio-controlled.co.uk one of my fave vendors

Fantastic service and advice from radio-controlled.co.uk, couldn't have helped any more, thank you. Really impressed with the quality of this buggy, extremely well built and looks amazing. Everything just looks well made and put together. This buggy is seriously rapid 👌
