Mine is very simple. Just a steel plate with clamps on our carport corner post. I drill and tap additional holes as needed for different engines. A typical motor mount can be installed for a glow engine.
This is not a great picture or video but it is all i have at the moment. If someone wants more detail, i will take more pictures. Here is video of it in action
