Well I recieved my Sig lt-25 yesterday and just finished the left wing panel today. My modeling experince is limited to r/c cars and some r/c heli. I also built a Dynaflite wanderer when I was 14 (about 14 years ago). My observations so far:
1. The laser cutting that I have been reading about is awesome. I can remember one of the most tediour task for me on the wanderer was tracing around each rib with my x-acto to get them out. Due to my lack of skill I always ended up cutting too deep into a rib by wandering off the the die-cutting. The sig ribs fall out of the sheet and are very smooth around the edges.
2. The instructions and plans are very clear so far. Even a newbie like me was not confused to often. The little tips they include obvisouly had the beginner in mind, like takeing the pins out of the bottom sheeting before applying the top sheeting.
3. Everything fits together very nice. You littleraly building the wing and THEN glues everything, it fits together that nicely.
I am having a blast building this plane so far. So much so that I even called in sick to work on it a bit (sshhh, don't tell the boss) I will post more updates as I progress further on the plane.
