The Tacocopter post is something that appeals to a lot of hackers. It's a wicked cool and potentially super dangerous idea. It intrigues people on HN. Hence it is discussed to the death.
Your post is titled 'feedback please', and yet you have not really mentioned what you want feedback on. Is it your business idea? Is it your YC application? Neither of these are mentioned here. Even if they were, the most that HN users could give you would be something along the lines of 'I'm sure YC is not averse to funding non-tech people.'
