Hasegawa 1/72 MV-22 Osprey
My Osprey build was much like the actual Osprey development. It took much longer than planned and plagued with issues.
This kit is not an easy one as it has a number of sub assemblies that need careful work like the props as well there is a lot of detail that needs to be protected during the sanding/filling phase of building. Added to this is the complex paint scheme which requires a fair amount of masking and the decals which I found to be a headache (especially the sensor decals as you can see in the photos.)
By the time I was finished this model I was just glad I got it done. Completing this kit, I found out why we haven't seen many built. ETA: it is the complex design of the real life vehicle that makes this kit a difficult build, not just the kit itself (kind of like the F-14 Tomcat.)
It does come with a stand and I posed it for flight (with painted crew figures) which does save a fair amount of space (the Osprey is much bigger than I thought.)
If you take your time (especially with the decals) this will make a nice model.
