ARRMA Granite Hits 72 MPH on Just 70% Throttle! 🚀 3S vs 4S Belted Tire Test #RCaDayChallengeJuly2026

‪@AMain_Hobbies_2‬ The new Upgrade RC LowPro Belted Street Radials finally made it to the regular speed spot, and today we put them to the test on both 3S and 4S power! The results were impressive. The truck tracked incredibly straight, stayed quiet at speed, and inspired a lot of confidence. Speed Results: 🏁 3S (Zeee 3S - ~70% charged) 60 MPH @ ~70% throttle 65 MPH @ full throttle 🏁 4S (Zeee 4S) 68 MPH @ 50% throttle 🚀 72 MPH @ just 70% throttle! The crazy part? We still haven't made a full-throttle 4S pass with this setup. There's definitely more left in it! Let me know what you think of the new tire setup and what speed you think this Granite will hit next! 🛞 Products Featured Upgrade RC LowPro Belted Street Radials https://www.amainhobbies.com/upgrade-...
