I was driving my Firestorm with my brother's savage and we were about 8-10 yards apart facing each other.We both mashed the throttle and while my firestorm front end was just lifting off the ground the savage comes in and collides into my firestorm and my firestorm bounces back about 10 feet [:@]and then it just keeps on going!Later I was checking for damage and found nothing! That just goes to show that HPI is almost bullet proof!(We were both going about 13mph with the throttle wide open!)
