Hi Dave,

This must be the day for Pitts threads. Three in one day. I just posted a thread on mine. Pitts with a DA 50. Just finished the airplane today. I listed most of the detail in the thread. I used 2 ailerons on my first Pitts. You don't want to hear the story of what happened to it. Let's just say it was my error. Anyway, it flew great with two ailerons. I decided to use four this time simply becasue I didn't like the slop in the slave rods that connected the upper ailerons to the lower ailerons. Pay attention to the firewall commets on multiple threads. G.P has certainly improved the firewall. Even using good ply in the newer models. Even so, make sure you remove the flimsy tristock around the mounting box and then reinforce. I pinned mine, added fiberglass and then put tristock inside the box and inside the fuse to the fuse firewall. I put a good bit of epoxy inside the the fuse where it connnects to the firewall as well. I actually could see light between the fuse firewall and the fuse side pannels. Not good. I have posted a few pictures below of how I reinforced the firewall. Hope to do the maiden flight on mine next weekend.
