First impressions on the kit, wood is pretty nice, though Ido notice that there is a great variance betweensome of the wood, for example a could 1/4 x 1/4 sticks are very light, around .003 kg to heavy around .014 kg. Same with the wood the ribs were stamped from, some dense, some really light, which makes me beleive its all cut and stocked before putting into the kits, and not cut and kitted like I have seen with some other kits. The die cutting on W1/W3 parts was half and half, some cutting was good, and some not all the way through, especially the W3 ribs. The W2/W3 ribs though came right apart after some light sanding, the other ones had to be cut with a knofe, it would have taken too much wood off sanding them. All the wood is straight and clean, and demensionally perfect.

Ihave all the ribs out, all the wing parts separated and then I weighed each piece, and then grouped them into left and right wings, marking the wieght on each piece.

Isetup my work table, grabbed a sheet of drywall and screwed it to my workbench, laid the plans out, and then covered them with the leftover plastic from the Monokote I used for my other plane. What I did with the plans to help them lay flat, and I must say SIG rolls the plans the right way, printed side out. I laid them out for a day with weight on them, then rolled them backwards, and left them for a day, then I unrolled and rolled them one more time, this way from the bottom up instead of from the side. When I was ready to lay them out, they lay perfectly flat now.

I started the left wing tonight, and each and every piece fit perfectly. Spars laid up nice, all the ribs fit snug, tacked all the joints with thin CA, then put the shear webs in, and for some odd reason Ithought the rear webs went on the 1/4 rear spar, DOH, so I had to cut them out and redo them, thankfuy Ijust tacked them with CA, they go on the face of the trailing edge sheeting. Once I got that corrected I then ran a filet of Elmers wood glue using a syringe to apply it. The next step was to install the wing bolt block, then I sanded the trailing edge to line up with the ribs, and then glued on the top trailing edge sheeting with Elmer. Then the top spar and 1/4" spars were installed, all but one can be installed at this time. Ithen ran elmers around all the joints I could reach. The wing is now drying, it is at the stage where a few more small items are attached, and then removed. Once I can remove it I can then reach the rest of the joints and run more glue around them.

The ribs are installed heaviest towards the center, so rolls should be nice. Ialso left the last rib out, which will let me transport the wing in the back of my truck without it sticking out. Overall length hits around 73", normally its 81". Iplan to put rounded tips on, so add about 3 inches, and it will be just under the length of my trucks bed.

A few things I am changing from the kit are with the fuse. Iam moving the elevator servo to the tail, and running a pull pull system for the ruddder. The radio tray that was in the ARF separated cleanly, so I may use that instead of the one in the kit. Going to make a hatch in the nose so I can install the batteries and ignition module, the fuel tank will go over the CG, so I may not need the tank floor. Going to use a Dubro Iso mount instead of the kit mount.

PICS added

1/8" are what I used, work just fine.
