Hi Dave
How are you doing and it is great to see that you still have an interest.
My plane was flown last July by a retired Navy fighter pilot/retired Delta 737 driver who happens to own an RV7A. My plane is hangered in a Delta retired 767 driver (Hurricane..1L8...) that flys an F1 Rocket. These two guys have flown about every style of GA aircraft out there and still they own and fly ....EXPERIMENTAL...
Now for me. I came to aviation late in this lifes game and thus don't have the real world experience of your uncle. But, as the others have said the Experimental world is very mature. From safety/design/panel options/engine options these planes when built methodically and with craftsmen like skills they are as safe as this type of travel will allow. By the way the skill set can be easily learned even by this old retired school teacher. Just think how easy it will be for a fireman.
It took me 4 years 10 months and 10 days to get the job done. I learned a ton, enjoyed the build, and have really enjoyed flying my creation. For me it was a twofer. Build and Fly.......I am still to this day finishing cosmetic details and adding APRS....
You had a chance to see my plane during the build so I know that you have no illusions as to the level of commitment it takes in time, $$$$, effort, frustration, highs, lows, (or LOWES aero) it takes to get the job done. But what joy during the build and at the end of the build line. FLYING a fast/new/sophisticated aircraft similar to or less $$$$$$ than an old GA aircraft.
The electrical and FWF stuff in my early thinking was problematic but in the end was the most enjoyable. There is a ton of info/EAA gurus/books/VAF search/ that will be your guide.
Dave if you really want to do this and include your family for a fun journey don't let the committee of "THEY" (even the ones you love) steal your dream and wonderful family experience.
I will look forward to your post that says,"Emp ordered and on it's way".
Good luck!!!!!!!
Frank @ 1L8 ...RV7A.. Flying snd APRS Tracken!!!!!!!!!!!!
