Take control of your RC car’s performance with the GoolRC Programming Card! This handy little tool lets you customize settings on compatible brushless ESCs from HOBBYFANS, OCDAY, and GOOLRC brands. It’s super compact at 8 x 5.4 x 1.3 cm and weighs just 31g, so you can toss it in your gear bag. Adjust things like maximum braking force (from 25% to 100% depending on amp rating), reverse force, start modes (soft to strong), low voltage cutoff, and neutral range. With four simple buttons—ITEM, VALUE, OK, RESET—and a clear indicator light, it’s user-friendly even if you’re new to tuning. Perfect for 1/10 scale climbing cars and other RC vehicles. Get the exact driving feel you want, whether it’s smoother acceleration, better braking, or longer battery life. A must-have for RC enthusiasts who love to tweak and optimize!
