Building an Experimental Airplane, The Vans RV-7A - EP1.13 Assembling the Tail - Ryan Flys A short episode, but still interesting (I hope!). I start to assemble the tail, but am quickly met with an issue that takes a pro to figure out (hint: the answer was on the plans). We visit my local EAA chapter, and get a peak a the new Van's RV-15.
