Hi Leardriver, I am most of the way thru the build on mine. I can help a bit if you like .. PM me. It's a beautifully made kit ... plenty of work to do in the build.
First step is to go to the Paritech site, there actually are some good pics that help id parts and show how to do things:

and

In addition there is a pretty good build thread on a German RC site, some of the posts on this thread may have come from there:

It's not too hard to wade thru it using google translate or a browser that can do language translation.
The speedbrakes do take a bit of work, the key is to get them in before installing the engine formers... otherwise it would be very hard to reach where they have to go. I can send you some pics, or perhaps I should post them here.. I did not feel comfortable with a micro servo on the speedbrakes and used a standard size instead .. just opened up the mounting plate holes a bit.
