Work continues, on the wing panels left wing is sheathed and the right wing is framed up and ready for sheathing. If you look closely you will see the blocks added for the hinge point mountings. Given that I up sized the rear spar/aileron mount they may well be overkill but I added them anyhow. In the course of this build I have made the decision that the ailerons need to be shaped to fit the contour of the airfoil better. In order to do that I will be adding a carbon fiber rod to the rear of the Aileron/Flap sections that will be used as a guide to sand the ailerons to shape before a 1/32 thick sheathing is applied to them, to which the carbon fiber veil will be applied after. Given the stressed skin construction I am looking to do this should not adversely effect the overall strength of the aileron or flap pieces, and remove a lot of weight and drag that I would have had with the slab ailerons. The best part of this is that now I am closer to being able to start on the construction of the fuselage, to which I intend to make many modifications to enhance overall performance as well as add side area ahead of the COG in order to improve Knife edge performance. A good portion of the added side area will be due to the inverted engine mounting, full cowl and hot air exhaust that will be added to the lower forward portion of the fuselage. As Red B. said in a post regarding the knife edge performance on a thread asking about Something Extra Mods. the real solution is to add side area rather than just increasing fin and rudder area which is a stop gap solution to the problem.




One additional note.

In the manual they say that when the top of the wing is sheathed and removed from the board it is easy to twist. I am not sure if it is the boxed spar, additional framing for the servo mounts, or the full sheathing; but the left wing is very stiff and resist twisting. Now I still intend to support the wing as they instruct in the manual when applying the bottom sheathing, I am very pleased at how rigid the wing is even befor the bottom sheathing is in place and how light it feels.
