Just two words of caution on trailers- THEY BOUNCE. Unless you have pancake flat roads , they can rattle a small plane and do damage. Yes, many of the IMAC boys use trailers, but since

their planes are much larger/ heavier, they tolerate the pounding and generally stay put with a restraining system.

Unless you have a family , consider removing the back seat if it is possible.

Leave the front seat in just in case you get lucky...

Ron Lockhart carries a 2 meter ship in a Toyota Scion. If your Civic is a 2 door hatchback; they're about the same size.If my memory serves me,he removes the spinner &prop.Also, it's not really hard to do a removable rudder.

Good Luck !
