Very simple kit. Started it this eve because I ran across it in my stash and wanted to build a Hawker and wanted something quick. I fought like crazy to get the pilot seat etc in the cockpit, modified a couple things and finally got it how I wanted. Then I looked at the directions again and realized why it was so difficult. Apparently I was supposed to mount the pilot to the seat and install that into the cockpit and then add the floor. I had simply mounted the chair to the floor out of habit so when I was looking at the instructions it wasn't registering that the floor was not attached to the seat.
