Default RE: Multiplex Big Lift II

I need your advise!

As I told you I'll be using my BL to drop R/C skydivers and I'll be starting with dropping one from its drop box.

I'd like to locate this drop box inside the fuse but it interferes with the steel plate the wing struts connect to. So I can mount the drop box onto the outside or inside the fuse but a less closer to the CG than it is possible with the outside mounting.

Let's sum up with the 3 mounting options

1. EXTERBAL drop box right behind the main gear = let's say neutral to the CG



2. EXTERNAL drop box over the main gear = slightly negative pitching moment?



3. INTERNAL drop box right behind the wing struts attachment bracket = positive pitching moment



Do you think the trimming may deal with this last option?

The CG is located right in front of the long hole

Thank you for your advises!
