Its a beautiful model and although I'm sad it wont be whole I am excited to see how it looks when done, very dynamic I think. One thing I would comment on is the position of the prop and I hope you dont mind is I believe even if they cut power and the crate nosed over with the prop in motion it would still make a small furrow and the break would be between 7 and 9 oclock rather than at 3 oclock as shown. Of course I am probably over thinking the process.

James,
Many thanks for the comments I appreciate all the help you give! - right now I'm just playing around and thinking about how to balance here to create the scene of the actual aircraft I'm replicating:

As you can see from the photo that everything about this bird is unique........ including the crash. This seems to be a classic example of the Roland nosing over on a soft landing - possibly the axle breaking and the aircraft going over as the right side dug in - the wing is intact with no visible damage as it looks like the wing tips didn't even touch the floor.
I think the propeller was probably stationary, the Roland was notorious for going over and as this is an early production C.IIA then I can imagine the pilots were well aware of the hazards of landing and switched off the engine to prevent damaging it if she did nose over.
As only one side is broken it suggest she leaned on it as she went over and the engine weight snapped it, the aircraft nose and part of the fuselage is sat in the furrow, which will help a lot with the positioning.
