Hi

I am building A graupner Kit Wiesel and have run in to some trouble. The problem is that when I try to seal the prop shafts and the rudders it allways turns in to a big mess when I say mess i mean glue every where, I try to sand it away but I still get it wrong and when I look at all the other boats I dont see any glue whitch hakes me think how do they do it? I am open to any good idears.

Here are some pictures to let you know what I am talking about and how I want my boat to look like:
