I would back the quality of my homebuilt against any factory built any day
Every rivet we stuffed up, we drilled out and replaced. With a factory built plane there is a percentage of rivets that can be 'average'
My aircraft is fully primed, priming is an 'option' for buyers from some manufacturers.
I would go further and say my 'homebuilt' is far superior in every area than any factory built. Hands down!
