When I had 500mm booms and 15 inch props my cinestar fit inside the trunk of my altma just fine. It actually had a little bit of room to clear. Now with the 550mm booms and the 16 inch props I can't fit it in their with the props on. The question I have is how much space do you need between the props? Currently I have about 1 7/8" inch between adjacent props and I was wondering if I cut the booms down slightly if it would give me the needed clearance. My question is how much space do I really need to keep? Can I take them down to 1" space between them? Is there any adjacent prop wash that will be worst if I narrow the space between props? I don't want to affect the flying characterics.
