I have a 2s venom Lipo battery, the ESC is currently in Lipo mode and ready to go. However, my stampede has not been run in over 3 months. I just got a fresh blanket of snow and im looking to take it out. Here is were my question comes in. When i try to gun it, (full throttle) it makes this whining noise and the tires don't burn out. Not even a wheelie. I could wheelie all the time but now it doesn't anymore. I put the ESC into the highest settings, (race mode) could it be because of that? Thanks.
