As we get closer to the completion of the kit, there are many random things that we must “finish up.” This list is nothing more than a random brain dump of those items as we think of them. On occasion, we’ll organize this list a bit. When we complete an item, we’ll move it from “Future” to the day that we completed the item.


(A=Anyone, J=Jeremy, S=Sam, L=Lucas, JS is Jeremy & Sam)

Before First Flight

  • Perform another conditional inspection (up close)
  • Install inspection panels
