I hate to beat a dead horse but I feel that I would share this with everyone and let you be the judge.
I am posting some pictures that are taken directly from the instruction manuals so that you can better see the diferences.
This is the way the wing is mounted in the kit version. Notice that the wing is completely surrounded by fuse structure.
This is the way it is mounted in the ARF version. ONly contacting half the fuse, and the lower half of the fuse structure is cut away and replace by a cover plate that is screwed in place, providing no support for the wing at all. Also notice how minimal the structure of the fuse is.
This shows that the kit includes frame doubler for added support all the way to the engine mount.
This shows that the ARF includes NO doublers at all, even though the design of the ARF needs it the most.
