Its finished now and closed up but this was a video I took when I came up with the design and initial implementation.

My RV-4 system
Here are some shots of the system I put in my RV-4 during build. This is the standard VANs set-up. The dive motor/jackscrew is horizontal in the tunnel on the left side. There is a pivot lever that attaches to the drive motor and is fastened to the R/H side of the tunnel with a bolt that goes through the belly skin and an angle on the tunnel. The unique flap weldment arm is different than the manual flap weldment and has a horn that connects to the pivot arm via rod end linkage. I have a small R/C model wire link to a position indicator X-ducer for the Ray Allen indicator and control my flaps via pushbuttons on the stick. I really like the set-up, and have sidewall panels that cover all the flap actuation arms, so there is zero chance of PAX fouling anything and better footwell room as well. I have seen some sidewall mounted actuators that have been adapted to the standard flap weldments that work equally as well, however this system was easy to install during build.

Here is an old web page from my Rocket build when I repurposed an actuator from an RV-9, mirroring the standard RV-4 electric flaps system.

As Scott pointed out, we do have the new style kits for the Rockets and Raiders available. Whether they could be adapted to any other RV-X aircraft, I do not know.
I believe that what Todd (xkuzme) wants to see is how the flap rod cut out in the fuselage side and bottom is shaped. A couple of photos would help, but in the end it's a trim and fit operation specific to each set up.
