Les gave good/great advice, but I will add a bit more, --- you being new to all this, may not have heard.
Simply the 1 in 10 rule of building.
That is 1 change from plans, easily will/could/often does, make 10 more changes, either in time added or parts that need to be changed or combination of both. Only with years of experience does this not hold true. But it does catch the best of builders at times.
And this does NOT take into consideration, of how it is going to fly...when done. I don't think anyone would want to add "discouraging changes or complexity to a plans built craft"
