I have been doing RC flying since about 1994, but have been involved with just about other RC stuff (cars, boats, sailboats) and have been building wood and plastic models since I was 8 years old (I'm 56 now). Over those years I've met up with a lot of "gurus", so called experts, and know it all's. There are only 2 people that I have ever considered to be THE BEST portals of advice, wisdom, help, etc.... The first was my dad. He was the man that got me into modeling and no matter what question I ever had he would sit me down and work me through it or help me out in whatever way was the best. The second was Mike (Minnflyer). For Mike it was like him being my dad, but for everybody no matter where they were. He loved this hobby and even more he loved helping people out in any way, which can be evidenced by his long list of helpful videos and posts. He was a great man and the hobby really lost when we lost him.
