Default RE: SIMLA BUILD THREAD

Final set of wing pictures, (unless more research into specific angles is needed), this time featuring my wing. These pictures give a feel for how everything fits together. Taking a cue from Jeff about his future plan for the kit, note the crude removal of wood...especially from the plywood ribs.

Note top sheeting is already in place in one photo, the jig has been flipped over, and the rest of the "bottom stuff" added. In the other pictures, the pre-sanded top sheeting is about to be added, while the bottom sheeting is being glued in the background, held down by big lead weights I got 30 years ago, (lead stays "fresh" for a long time). After gluing and drying, a second bead of medium gap filling CA is run down from the L.E. and T.E. on each rib to ensure there are no gaps.

As mentioned earlier, you can see some of the wood weights written on the spars to make sure the heavier pieces are sent to the left wing, (the sheeting weights have already been sanded off). If there is a marked difference in the weight of the pieces, avoid ALL the heavy stuff going to the same wing half to keep from having to add weight to laterally balance.

A more traditionally modern 2-servo system was used for the ailerons using modern extensions. Protect the wire where it goes through the holes to protect from possible vibration damage.

The false L.E. and L.E. are added after the sheeting is complete, and a center line drawn to make sure the sanding is uniform on both sides, (when sanding, you don't want that centerline to be sanded off). The little magnets are great for holding everything in place without pins.
