Thank you Jeff. The only mods for this one are for weight, without sacrificing strength. Such as the tail feather mount, they have brass tubing with piano wire (high carbon steel) inserts. I changed out the brass for one size larger (the closest size in standard) and replaced the piano with brass. I eliminated one ounce doing this. They also had a boxed tunnel for pipes, I am not running pipes. So, I removed most of the hardwood, just used what was needed for a fuel tank seat.
I took today off from the build to rebuild my thrust test stand. It was in need of some new wood and new sliders.
