Some people build the FT swappable planes but glue the power pod in place instead of swapping out the pod from plane to plane. I am one of those people. I don't usually have multiple planes flyable at the same time and I usually land on the nose. Which can bust up the power pod.
But a swappable is just a plane with the FT power pod. Which is meant so you can remove the pod and insert it into any of the FT swappables. Great idea, but it's not for everyone.
