Okay folks:
Just to bring you up to date. I have buttoned up the fuselage, but; here is what I did prior.
I drilled out the holes in the back of the seat mounting frame for rigging and ran the rigging from the back for attachment. I used EZ line and CA glued it to the back.

I then CA glued it to the rudder peddal and the control stick.

I went ahead and used the HGW "Fabric" seat belts. I attached them to the seat belt springs on the frames, draped them over the seat and CA glued them in place.

I am not sure if they look any better than the painted PE ones. They are a lot more fiddlly and I spent hours on them. Not sure I will go that route again.
Using EZ line I represented the lines coming off the control column. I am not sure what they are, but they are seen in the data file and they were easy enough to do. I have the fuselage buttoned up and am ready to move on to the next step. Stay tuned for more modeling mayhem.
Thanks for stopping by
Mark
