Yea the Cessna is Apex so can be added with the rest. A3EAI is actually the Roaming AI script that runs server side only so you don’t need to install it. Epoch experimental is the development branch of EpochMod so it has the latest additions but also bugs potentially as it has not been tested enough to reach the stable branch (which is what most Epoch servers run including ours).
