Short version is: RTFM

Long version: RCU Board is not a good tool to create a Knowledge Database but but we have it in this thread. Lots of knowledge, experiments, results, recommendations and mistakes. It is long manual, almost 2 thousand posts, but it is worth to read to understand where we came from and what we (as a gropup) accomplished. There is no realy one word: "10/10 2:1". It did not work for me, duh... but works for many others. I use "15/18 1:5" but I explained in detail why. You have to read this Manual to understand. Yes, I was lucky - I joined the thread when it was only 7 pages long (my first post was 154), now the reading is enough for days. But I can assure everybody, it want get any shorter

Now the answer to KI8FR question: I would recommend to READ first then ask questions (like I did [link=http://www.rcuniverse.com/forum/fb.asp?m=3118789]"It took me a while to read all pages"[/link]). If someone wants to cut corners and get everything explained in one post, he will be missing a lot. Even posts describing a failure (like mine in example) bring out the knowledge and let everybody learn from mistakes already made.
