Default Texas Fastback 2.0

124TT has made it safely to its new home in Germany. I hope the new owners enjoy the heck out of it. We decided to build another fastback, this time starting with a somewhat blank canvas with a partially completed kit. We thought we looked it over pretty good but I guess not good enough. I'm not going to mention any names or where I got it, but we have already ran into a major screw up that requires major surgery. It requires removing and replacing the top and lower longerons and the firewall weldments that they attach to. Hopefully after this is done we can actually go forward with this build instead of going backwards. I would like to know how others have solved this problem of getting the correct edge distance and fit? pictureds would be nice.

Good luck! I am sure this one will be just as nice.

Looking at those pictures, I would be suspect of every single point of prior assembly from the previous builder. Good luck with you project.

Actually the rest of the build looks pretty good. There are a few rivets that need to be drilled out. The good news is that the wings are still open and the fuse is a canoe. If this is the only boo-boo then after I get these longerons replaced its off to the race. I will definitely look everything over carefully before it gets installed. This is my second RV-4 build so I have a pretty good idea how things should look.

On my RV-3B, I decided to start with 1 x 1 x 1/8 angles and narrow them down in between wide spots. My VAF blog introduces them in this post.

That's post # 246 in this thread.

The subsequent posts don't particularly emphasize this feature - you can get glimpses of it - but it's definitely proving to be a good one. I'm glad I did it this way.

I remember that the narrowing took a weekend and left the shop with tiny aluminum needles. I had to make many, many passes with the shop vac to keep things under control.

I need to fly up and check it out. Didn't know you were getting another.

Interested in your opinion about the fastback vs. plans.
Do you think it is worth it to re-build an existing (and flying) canopy to make it a fastback?

Builders preference. I think it looks better. I got the longerons out and have the angle on the way. I went with Daves suggestion and ordered the 1" angle. I'm not sure how it will bend in the reqired areas and may have to notch those out. I may also need to build a jig to make sure everything goes back together straight and level. It's pretty flimsy with those longerons out.
