Welcome to the board!
Bookmark this website, http://tech.vtxoa.com This is the sister site to this message board and contains all your How-to/Tips/Tricks/Why’s and links to other helpful sites for your new VTX.
There is also a helpful red Search icon at the top of every page(not the Google search). Enter your item to be searched in the "Search Query" section and click the "Search for all terms" bullet under the query. Then go to the "Search Options" section and choose a board from the "Forum" drop down menu. This will limit the results to your search so you won't get pages of "Fluff" .
The pupose of the "Search" is to offer a member the opportunity to research his/her question better. There is so much information from past threads that you may never see because that member is no longer here, or doesn't see your new post, or just won't respond to the same question. So use it to your advantage and enjoy the board! View this funny and informative film about posting and searching… http://uploads.ungrounded.net/188000/188612_Posting.swf
Also, take a few minutes to familiarize yourself with the forum. At the top of every board there are threads that are tagged as "Sticky" These threads are "Sticky" because they contain very important/valuable information about the VTX and everyone should read them.
The thread at the top of the 1800 tech board called, "Air, Fuel, Motors..." will answer most of the performance questions... http://www.vtxoa.com/forums/viewtopic.php?t=28918
Also, update your Profile to include what type X you have to your Signature line. I.E. 1300/1800/C/F/N/R/S.
