<div class="">There are two answers to that question. The simplest is that you will make a 4-grain 38mm during the class which is a K, so to fly it, you would need to be level 2. The class gives you the hardware to make 38mm grains. However, if you buy hardware
to make other sizes, you can make anything from a 29 to 98 mm.... level 1 through level 3.</div>
<div class=""><br class="">
</div>
<div class="">To fly them, we have to declare that a launch is experimental. Other than greater set back distances, it looks the same.</div>

</div>
<div class="">1) four sets of 38mm 3-d printed tops and bottoms for grains</div>

<div class="">and consumables</div>

<div class="">3) for 38mm paper tube sections about 2 inches long</div>
<div class="">4) a liner that fits in a 38mm case which the grains sections in paper tubes slide in to</div>
