hey guys! i just got a mini inferno a couple days ago and i'm new in this hobby so i have no clue how things work hope you guys could help me. after running my mini inferno i noticed that the response time from when i squeeze the trigger to the car responding takes a while ( i have fresh batteries on both the car and radio). plus i want it to run faster but i don't know where to start. the guy in the hobby store also told me that my slipper is loose. i asked him for some input but he was just too busy. i tried tightening it though following the manual but it was just impossible to turn with the plastic wrench that goes with the car. what is the slipper for anywayz? hope you guys could help me. thanks!
