There have been several methods of flap attachment on the RV-4.
1/ Hinge pin may be cut and bent at the middle of the flap allowing each 1/2 to be pulled out from there.
2/ Many people drilled a hole in the inboard aileron hinge bracket slightly out of line with the flap hinge pivot point allowing one to bend the pin slightly and pull out through the hole.
Look at each end and in the middle of the flap hinge. Shouldn't be too hard to figure out.
Of course the flap pushrod must be unfastened too. But that should be obvious.
