Disco if you look you will see the tube for main spar. It is just like the smaller hawks across the board. The Airex is the same that is used now by most of the China jet manufactures.
I am pretty sure a lot of these come from one plant in china. That is the main molds. The difference seems to be is the final assembly, glue, paint and the type of formers. It appears some use carbon fiber and others use hardwood or a combo of them. Also some us a different landing gear. They use a different vendor or make it themselves.
I have asked if 2 of the new offers of the large 1.3? scale hawk coming out will be available in the 100 and neither is offering at this time.
I am pretty sure they are waiting for the mold maker to build the 100.
