Ordered a new brushless motor and ESC combo for my crawler, and it’s working like a dream. Shipping was surprisingly fast, and the parts were exactly as described. I had a minor issue with the wiring, and customer service helped me figure it out over email within a few hours. Great experience overall.

Just got my first RC drift car from this site, and it’s been a blast! The car arrived well-packed and in perfect condition. I had some questions about the best batteries to pair with it, and their support team was quick to respond with solid advice. It’s refreshing to deal with a company that actually knows their products. Will definitely order from them again.

Delivery was a little late (3 days), but arrived 1 day late. Think this was royal mail to be fair. Everything else good!
