You will find that the search feature provided on a lot of these sites is rather under-powered. I suggest you use a Google "Site" search, basically you specify your search string and the website in the following format in a Google search box and all the answers are given unto you - The google has spoken...!
Search Format: search string site:rcmodelreviews.com
Hope this helps...
Also, Bruce, I don't see any topic headers on the main index part of the forum that relate specifically to radio transmitters etc... Just a thought...!

PS, if you ever plan to start on the "build your own 2.4Ghz transmitter" thread again, as you know I have an old JR transitter sitting around here that is in need of some new brains to make it work again....
