All, I am 6'3' but I have long legs. I purchased and RV6A and my knees were hitting the bottom of the instrument panel (standard panel). I installed the Antisplat Areo seat mod, and what a difference!!! this should be standard in al the new 7 kits, the difference is amazing!! I also added another row of piano hinge about 1.5 inches back. my legs are now slightly bent like they should be. I highly recommend this mod to any of the 6s. The Antisplat Areo guys are outstanding to deal with!
