Do you know what a search engine is. Stop asking stupid questions and do a little research. If you want to know what Yellow Aircraft is...type it into a search engine. It'll show up every time. Click on it and go there.
There is a website called RCOnline that will be happy to have you asking all your "what's a TX" and "how do you hold the controller thingamajig" Dang, I feel like I'm talking to an 6-year old.
Don't you have some studying to do or something.
