I just visited my buddy, Brooker...
...in Sandersville, Ga. yesterday. He's building his 4th RV and is in the middle of flap construction. You won't believe that the RV-3 plans show 3 different length dimensions!!! It really takes some head scratching.
All of you -7/-9/-10 builders can't really appreciate all of the pre-punched stuff until you plans-build, like the -3.
