Safebet, good luck with building the Decathlon. I think you will not have many problems. It was the first kit I built and I didn't. The instuctions are very good. The only thing that I want to add to all that is posted here is that, if you haven't already, read the following suggestion from GP:

I think they changed the manual sometime to include the washout, I don't know which one you have. I didn't built any washout because I had an old manual and by the time I read the note it was too late.
Now, about donkey doctor's post. I have read simmilar comments from many about this plane. I really cannot help you with that. I know that they are all telling the truth, but I really can't tell why it didn't happen to me. The only thing I know is that mine flew great. It was my first kit built, so I don't think I build very well. I know for I fact that I build heavy, because I use too much glue (I have not seen anyone build a kit, so I cannot tell how much is enough and I prefer too much than not enough). I had not flown for a few years and have never flown another tail dragger before, so trust me when I tell you that it is not my flying skills either. If you look at the video I posted, you'll see that I didn't have any serious problems, except bouncy landing, which I'm sure I'll get better, especially with the stonger landing gear I've ordered and still waiting for.
Again, good luck with building it. And ask as many questions as you want. I built it just a couple of months ago, so it's all fresh for me!
brschmid, good luck with yours too. Take your time, fly it when you feel ready, but don't be afraid of it. I know I was, but it turned out to be anything but.
