IT WAS JUST MY FIRSTIME DRIVING WITH BALLDIFF SETUP HAI IF I HAD MORE TIME TO DRIVE THIS CAR IT WILL BE VERY CONSITENT IN MY OPINION WITH NO SUDDEN CHANGES IN DIRECTION OF THE REAR OF THE VEHICLE . BUT EVERYTHING IS DEPENDING ON TRACK CONDITIONS ANYWAY.. BUT IF YOU WANT EFFORTLESSLY FOR THE WHOLE COMPETITION THEN YOU HAVE TO SETUP YOUR CAR TO WHICH YOU CAN DRIVE IT THE WHOLE 5MIN. AND THIS DETERMINS YOUR MAINS POSISITION . SETUP IS VERY IMPORTANT TO HAVE FUN WITHOUT PROPER SETUP THE CAR WILL JUST ACT DIFFERENT FOR THE IMAGE YOU HAVE IN YOUR MIND. SO ITS REALLY BETTER TO SETUP YOUR CAR IN DIFFERENT CONDITIONS AND MAKE IT AS CLOSE AS YOU WANT YOUR CAR TO BE . AND TAKING NOTES ON HOW YOU DID IT . VERY NICE AND FUNNY EPIC VIDEO CONGRATULATIONS
Ball diff much smoother than Gear diff is fact, because both wheels at rear not a constant movement when wheels going towards when corner steering. However, more horsepower equipped (above 13.5T) Gear Diff has more reliable and efficient than Ball diff. So that, Apply Ball diff in Tamiya Champion (15.5T) will be a good choice.
Thanks again for your coming back. Yes so far I have same option that ball diff would be a one of best choice for tamiya rule race events. Hard part of using ball diff is build and maintenance. If user knew how to make it boom!
