Why Use Pre-Slotted Tubes?
The first big advantage is that it eliminates the need for a hobby knife during construction. You don’t need to worry about young modelers cutting themself. Pre-slotted tubes also means that when parts are assembled, they’ll be in the proper location. For example, the little slot on the yellow engine mount tube will mean the engine hook is positioned in the right location. And the slots on the white tube will mean the fins will be in the right location for maximum stability. Plus, when the fins are placed within the slots, you’ll know the fins are aligned perfectly straight. This means the launch will be perfectly straight-up, with no spinning or looping! Besides being safer, the rocket will fly higher too. Imagine the applause you’ll get when they see how straight your rocket flew; like it was riding a rail into the air. The through-the-wall fins also have another benefit. They make the rocket tougher, so the rocket can land harder without them popping off the tube.
