I apologize for not replying to your question about the Dynon autopilot.  I broke my back a few years ago and haven't been back here in a very long time.  The answer is unfortunately no, I didn't the autopilot installed.  I'm hoping to be able to resume activity in the next year or so.  Progress has been slow going.  But we just bought land in an airpark in Tennessee, so I'll have a new hangar to occupy in the next couple of years.  Assuming my healing progress continues in a positive direction that'll get my build going again.  Truth be told though, there was a whole lot of procrastinating going on even before I broke my back.  But my wife has threatened to kill me if I don't do something when the new house and hangar get built, so there's no better incentive.  Thank God for her!

Hi Jim, 

The centre rod preloads the spring. You can use it to take all of the pressure off the v-block. Without the centre rod, you can still adjust the preload with the outside rods, but by adding preload here, you are loading the v-block and making the rudder stiffer. (With less preload, the nose gear will compress more under the load of the aircraft) In our case, there is less load on the block now than when we had the bungee cord, so the rudder is lighter than it was, but not a free as it is when you can take all the load off. 

You still have the option of using flat blocks to lighten the rudder, but I don't think it is necessary.

I think that the headers of the 912 give off a lot of heat, which shortens the life of the elastic bungee. We replaced two this year.

Thanks for the welcome and for the offer to see your aircraft!  I work near Tipton and saw the news coverage about the accident.  I hope your friend Tom recovers quickly and gets back in the air.  Time to get changed out of my suit, drive to my brother's home and get to work on finishing the slats!

The two positions I picked were fully back and fully forward.    I used lightweight closed cell foam so my seats are relatively thin and even so my buddy is 5'7" and he found the position quite comfortable.    I cut the rudder control rods shorter to accommodate my legs.

Hi James.    I liked the seat rails, well built and would fit quite well.

I actually found during fitting the seats that the semi-recumbant position of the seat design fits different height people quite well.    Im all legs and found that I needed to position the seat all the way back to give me a comfortable fit and this position also fit most people.   Ended up just going with the design attachment and put a second set of nut plates forward about 4" for really short folks.

Easy enough to install seat rails later if the stock system is found wanting.

Dear James good evening!

I am trying to "force" the Airfox people to do the kit. Unfortunately is not the first priority for them so I had to wait. Soon I get news I will post it.

I put some rubber edging along the edge that is against the glass.  I fit mine before the glass and then refit after glass was installed.  I painted the skins seperate and then installed very last thing....touched up rivets with brush.

The covering on the top skin is part of the Zenith interior kit.
