You're reinventing the wheel Tom. RCU and many other sites have expansive reviews sections. The stickys at the top of this forum contain a wealth of beginner info, as does the website put together by a former major contributor here called www.gettingairborne.com. If those don't answer your questions, a few searches here on RCU or RC Groups will usually get you what you need. And, of course, when that fails, asking questions always works.
