10.4 is very good, exactly the sort of thing you'd want to see. Not sure what you're trying to point out by printing it here. Section 9 is also standard stuff, saying customers can't demand their money back due to delays. If they could then the company would go bankrupt because delays always happen in aircraft development. Even Boeing and Airbus take much longer than they anticipate. And regulatory approval can take forever. Luckily, in the US, no approval is needed for experimentals aside from one person looking it over to make sure it's not obviously unairworthy, like a contraption someone put together in their garage. Not sure about the UK or EU though.
