The TB5 represents a launched grenade used to disable, or destroy, a range of armored targets, tanks especially. This model rocket is an original design with military inspiration. It is not a scale version of a real device.

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.

The kit comes complete with the vinyl decal, plastic parachute, transition and includes the ejection baffle and aluminum motor retainer.

    This "scale-like" version of an anti-armor rocket propelled grenade is not only cool looking, but fairly easy to build as well. This improved version replaces the cardstock transition with a 3D printed plastic one. Also a vinyl decal replaces the stencil template of the earlier kit. You do have to sand smooth the micro ridges on the transition, however. Lots of fun to build.
