I commenced building the ground adjustable rudder pedal kit on 12 September 2015, and completed it on the 19th. The longest part for me was mearuring where the pedal rails were to be attached and drilled to the floor. I must have done it at least 6 times before I arced up the drill. It really was quite straight forward.
I also fabricated a set of rudder pedal extensions with drawings from aeropunk.com , which I found on VAF. Great drawings and easy to fabricate.
