I have a 4* 40 build thread here:
http://www.rcuniverse.com/forum/m_5599424/tm.htm
I just did the stock build, and it was my 1st 4* so don't think of it as a "How-to" but more of a "what did he do wrong so that I won't make the same mistake" thread.
saramos, are you documenting your mods? They sound great!
