Now, you've got an AI mechanic right there to answer your questions or bounce ideas off of, anytime, anywhere! Drivers love it: "This app is amazing. It's a game-changer. I love to 'talk' with the app, like 'I need this and I’m thinking of that, would it help me?'" - Gerardo M "I must say, I’m currently 25th, about 10-15 places better than I expected, thanks to the app. I’m asking everything!" Ask your AI Mechanic anything, such as: - “How can I get more rear traction?” - “How can I increase corner-entry steering?” - “What is roll center, and how do I adjust it?” - “How does Ackermann angle impact steering?” - “Which is better: a brushed motor or brushless?” Your mechanic specializes in: • 1/8, 1/10, and 1/12 scale cars and trucks • On-road, off-road, oval, drift, and drag racing Your AI Mechanic can still recommend pinions, too! Simply enter some basic details about your car and track, and your mechanic will guide you with tailored advice. Your mechanic already knows the basics of hundreds of the most popular RC cars, so you don't have to start from scratch. Once you've entered your cars into the app, switch easily between them, and your mechanic will always remember where you were in your previous conversation. Please note: Every car and track is different! Your mechanic will recommend setup adjustments and gears, but you’ll still need to test and fine-tune based on your driving style and track conditions. To easily track your tests and race results (as every racer should!), try our RC Setup App (link below).
