I found some more pics of the mohajem 92 and Kaman 12 forerunners and it now seems pretty obvious that both of these have been very heavily modified ftom the original.
We can now clearly see just how much has been modified in the mohajem 92.In addition to the new taller landing gear and larger nose we can also see that the tailbooms have been lengthened as have the vertical tail surfaces,also the angle of the verticals is far less and the winglets on the bottom of the verticals have been cut back to match.It looks like the wings have been lengthened as well.
We can see just how far both the nose and tail section have been lengthened,plus the extra reinforcing on the tailbooms,in addition both the vertical and horizontal stabilizers have been lengthened as well.
