I HAVE BEEN IN THE RC BACKYARD BASH STAGE OF THE HOBBY FOR 6 YEARS. I STARTED OFF WITH THE LOW LEVEL RC VEHICLES. THE DURATRAX MAXIMUM ST THEN WENT TO THE STREET FORCE 2. I HAD THE O.S 15 BLUE HEAD IN BOTH OF THEM. THE 2 SPEED STREET FORCE REACHED 49 MPH. I RECENTLY BOUGHT AN OFNA LX-1. MY INTENT IS TO AT LEAST START CLUB RACING. AFTER 2 MONTHS THE FACTORY .28 JUST PETERED OUT. I WAS GOING TO INSTALL THE O.S 21VG. MY LOCAL HOBBY SHOP TALKED ME INTO GETTING THE GO TECH .21 5 PORT. WITH A LOT OF HARD SELLING FROM THE STORE I BOUGHT IT. AFTER A DIFFICULT TIME OF BREAKING IN, I TOOK IT OUT TO A PARKING LOT TO TEST IT OUT WITH A FEW BUDDIES. THERE WAS A TEAM ASSOCIATED, REVO W/ RB523, AND KYOSHO. AFTER 5 MINUITES ON THE PARKING LOT I BALD MY FACTORY TIRES. I WAS REALLY IMPRESSED WITH THE POTENTIAL. THE OTHER BUGGIES HAD O.S. .21VG W/ JP-4 PIPES. I PUT A JP-4 PIPE ON MY BUGGY. I COULDN'T KEEP THE DARN THING STRAIGHT. I WENT BACK TO JP-1 PIPE FOR BETTER CONTROL. I STILL HAD POWER THAT I COUDN'T CONTROL. THE GO TECH IS A SECRET WEAPON. THE LESS OTHER PEOPLE KNOW THE BETTER OF YOU WILL BE
