Yea, here we go again. Whats up with these people that say VXL's cog so bad ??? I have one in my firestorm, and had NEVER experienced cogging. Then I read about it, and someone said it was when going extrememly slow...so ya know what, I tried it. Sure enough, when trying to go at a speed where the motor is barely turning (probably like one tenth of a mile per hour)...it cogged !! Damn....I'd never have known just driving the car at ANY normal speed...but ya, there ya have it. If you want to run your car at under 1 mph you could experience cogging...so you've been warned !
