RE: Sobre reinforcement bracing
You are correct. I finished building the rest of the plane and got to that step. In the directions for the other parts these carbon bracing pieces are not mentioned. So until I got to the end of the line with instructions I thought that they were extra. However I only have two of these. There are SFG's on both sides top and bottom so I should have four of them total. I only found two of this length in the box.
I bought a length of rod at the local hobby store. I tried gluing on the first top SFG. Couldn't get the thing to set in place long enough for the glue to cure to it. All I did was make the paint from the color scheme run everywhere. Going to try flying it w/o them first.
