I have a Plymouth Voyager as well, regular, not grand. As it is just me I remove both back seats and set the fuse onto of my field box and then the wing beside it, so far so good.

When I have my plane I use extra caution in where other traffic is so I won't have to slam on my breaks, but then using a SPAD, I don't have to worry about getting holes in my wings either (just on my other trainer).
