Anytime you go off plans, it creates a bunch of work and can add significantly to the timeline. However, adding cool features is what an experimental is all about.

Now, I’m not an aeronautical engineer, so I NEVER just go off plans by myself.  I have some pretty strict rules:

1. Does the mod affect safety of flight? I never go off plans on these mods. No mater who else did.

2. Would Cessna do this? I keep this thought in the back of my head as a guideline. Cessna Safe.

3. Is this a well documented mod? Are the parts involved aircraft parts?  Like adding parking brakes.  I’m in.

4. Is the mod a kit I can buy that many others have done? My Nav lights fall into this category.  LED lights for wings and tail. Thinking about Electronic ignition.

5. Have many before me done this mod?  Flap up travel limit switch falls here and in 4 above. I may buy the kit or do the Automotive relay thing.

6. Are the risks small?  Fairings on the rudder cable go here. My Avionics tray fits here too.

7. Cost appropriate? Am I overbuilding for the plane I want?

8. Is this a Real mod or am I just fantasizing about it? Rotary Engine?  Retractable landing gear?  Three seats?  Propane operated simulated machine guns????  Wow!  Nah…

For now, I’m building a standard, 150HP Lycoming, Mags and a carburetor with a wood prop. BUT after I’m flying a bit????  We’ll see…
