Sheeting the top of the wing now, starting with the D-Box.
I decided to attach the wing to the fuselage using dowels and wing screw in lieu of the rubber bands, which will require some plywood reinforcement at the TE centre section where the holes for the wing screws will be drilled.

FlyerInOKC - I didn't think that rubber bands and Petrol residue will be a good idea...
My friend David kindly routed for me the channel in the landing gear bracket.
It is now glued into place, which will allow me to complete the sheeting of the bottom of the wing.

FlyerInOKC - It better works... Fixing LG mounts is one of my hated jobs. This one designed correctly and should easily be sufficient.
I did some more sheeting over the LG mounts, and sheeted between the ribs where I will have the ailerons servos.

The deviation from the original design includes the installation of servo per aileron in the wing.
As the bottom section is made of sheeting, all future maintenance (if ever required) will be done from the top of the wing.
This will require to cut a hole in the Monokote covering and remove the servo mount, which will allow access to the servo screws.
I made a mistake, cutting of hole for the servo horn in the wrong place (D'oh!), which has been rectified.

FlyerInOKC - I prefer to sand into shape when I have the corresponding structure attached, but, I don't think there is right or wrong doing it either way.
And, talking about sanding, I got both the wing tips and leading edges done.

Thank you FlyerInOKC.
A bit more work done. Cutting the ailerons, filling the gaps in the secondary spar and the aileron "LE", then repeating for the other side.

FlyerInOKC - I hope it will be responsive, it was a pattern aeroplane after all...
Final touches to the wing before covering, cup strips glued into place and filler applied.
This must be up there with the best wings I ever built.

One of my favorite activities when scratch building is covering, especially when using Monokote.
Therefore, to have a break from construction the next stage is covering the wing in its basic orange, before making a start on the fuselage.
I started with covering the areas that are not part of the main covering exercise.
The plans have no hinging information and I think it is reasonable to assume that no hinging is required. It should be plenty strong to use the covering as a hinge. However, I decided to install hinges on the narrow section (top of aileron) and hide it under the covering (just in case...).

FlyerInOKC - I genuinely do not think that the forces on the ailerons for this model will be an issue for "Monokote hinge", however, it is a no issue anymore as DuBro hinges are in place : )
The covering of the bottom of the wing is done and the servos installed. Covering is like a therapy...
I need some more Monokote, so I will put the wing away and start working on the horizontal stabilizer.

FlyerInOKC - I will be duplication the colour scheme used by Phil Kraft as in the first photo I posted in black and white (re posted here), and the only colour photo of that aeroplane that I found (the further away aeroplane in the "Model Plane Building..." image). I also found the third image posted here somewhere on the Internet...

Cool! I have a partially built CG Tiger project that was given to me I was going to do the wing and the back 3/4 of the fuselage in orange and the wing trim and front of the fuselage in white. Here is the side art I had made. The project just screams for a Tiger..
