Last winter I was lucky enough to visit DF4 and the Arizona Skunkworks. While there I noticed Steve built his baggage compartment from dacron and glued direct to the tubes behind the seat. An aluminum frame keeps stuff from falling on the linkages. I liked the idea and this is how mine turned out.
Also did the wide body mod as I could not believe the room in DessertFox4's Model IV.
And I almost have enough room for my Travel Guitar.
