Working on an older RV4 that my buddy inherited from his dad. It was 1st flown back in 1986, just over a year ago we took it apart to bring it up from florida. While working to install the horizontal last weekend, we noticed it in no way matched the plans I have.
Bulkhead F-410 is a single piece that went from top to bottom, where as the plans show 410A and B with A being forward of B about 2" to allow the attach bolt thru longeron to go in front of the horizontal forward spar, where as this was built with just 2 bolts on backside of the spare, and 2 bolts going thru the upper part of the bulkhead horizontally.
Anybody else seen this, Vans can't find an older version of plans showing it done this way.
