Hopefully a bit more care goes into this engineering effort. If not, it will at least be a lot easier to find.
Going deeper into the carbon fiber issue, I see no consideration being given to the heat impingement from the turbine exhaust directly onto the tailboom. The adhesives they appear to be using are low grade/low temperature systems; not good. I worked on a composite tailboom program in the early 90s and one of our main considerations was heat exposure. We identified BMI resins as a solution, providing a heat shield would also be used. If you look at existing helicopters with metal tailbooms today, you will see many are now using heat shields for this reason.
