1.  Keep a good construction log and register the plane as an Experimental/Homebuilt. This will allow you to do your own annuals and make almost any modifications you want. This applies only if you have a strong mechanical background and don't mind asking qualified pals to go over your work. 

2.  As I upgraded my panel the wiring got messy. Make sure you allow extra length for maximum flexibility for re-locating instruments and installing new ones. 

3.  Pressure check the coolant system before the first start of the engine. My brand new "gold plated" Rotax 912 came with a leaky radiator cap that caused me to make an off-field landing. Some crystalline-looking crud was found on the sealing surface of the cap. When the system got up to running temperature/pressure it dumped some of the coolant overboard. 

4.  The angle of the rudder/toe brake peddle should be carefully set. I found myself putting the brakes on during landings because I don't steer with my heels. Installing an extension to the lower part of the peddle keeps my toes off the brakes now. Setting the peddle at the right angle during original installation is a better solution. 

5.  The fuel system plumbing had to be modified to include shutoff valves for each of the fuel tanks. I made up a small panel that holds the two valves. It mounts between the seats and is plainly marked to show the position of both valves. Photos upon request.

6.  I installed a fuel filter that is used in 912 powered jet skis. I like it because you can look directly into the filter screen and because it has a ring that floats on any water that is trapped in it's glass bowl. 

7.  I wrote a preflight checklist that specifically addresses my plane. It's on my computer and has been refined to address all design changes. It is not required by FAA Rules but really helps make sure she is ready to fly. A Pilots Operating Handbook is also very, very handy. 

8.  My Grand Rapids Engine Monitoring System has kept me safe and allowed me to concentrate on flying. The red light came on when I lost coolant (item 3 above) and warned me of the problem long before the situation became critical. 

9.  Shame on me for doing a hurry-up job on my first windshield. I didn't carefully round all the edges, drill the rivet holes to the exact right size etc. Cracks started showing up in several areas and I had to spend unnecessary time and money installing a new one. 

10. After flying with my son in his high performance/glass cockpit I became aware of the possibility of having a mid-air. I did not show up on his or any other traffic monitoring system because I didn't have a transponder. Pilots like him often do "approaches" on small air strips using the nearest VOR for reference. My beautiful S6 visibility would be of little help if I get rear-ended. I clenched my teeth and plunked out ~ $1,150 for a bottom of the line transponder. Now I am even welcome at the Class C in my area.
