Okay for better or worse, I decided to make some customizations to the rear seat. Honestly this is probably more work than it was worth and I’m not sure why I did it but it’s done now so I’m going to keep it….
I used a single sheet of aluminum to replace the rear seats. The idea was that it is about 3/4 of an inch less high than the Sling design.
So the passengers in the rear now have three quarters of an inch more headroom. Normally my kids will be sitting in the rear not adults so this most likely is not a problem anyways.
Also I had my son sign his name to the inside of the seat that him and his brother will be sitting on. They have been doing the dirty work of removing the plastic off of the parts for me. So it’s only fair that they get some claim to the plane.
