Tank Buster 5 This model rocket is an original design with military inspiration. It is not a scale version of a real device. The TB5 represents a launched grenade used to disable, or destroy, a range of armored targets, tanks especially. The Tank Buster 5's unique shape and six fins will make it stand out at any launch. The TB5 can be flown on B motors for low flights, or C motors for more serious action. Due to the launch lug location, a four foot long 1/8" launch rod is required to safely fly this rocket. $19.95  Dimensions Overall length : 27.25" Diameter : 1.637" (BT60) Forward Fin Span : 3.216" Weight : 2.25oz Recommended Motors Estes® B4-4, B6-4, C6-5 Challenges The main challenge when building your own TB5 model rocket is the transition.
