What is the difference of 3 channel and a 4 channel plane?
Flboy answered this one
I know there are certain "flaps" on planes what are they called and where are they located?
Some planes have flaps they are called flaps and the are located on the wing, But somehow I think you don't mean flaps
So I'll give you the names and functions of the control surface on most planes Rudder (controls yaw) Elevator (controls pitch) Airlerons ( control Roll) Throtle (controls Engine RPM)
What is up with the Trasmitters, recievers, and servos? Can someone define those to me and recommend some to me?
People can and have written books on this topic
As far as recommending gear you would need to provide more specific info
I hear a lot of talk about engine size, (electric) 280, 380, and 400 which one is more powerful? 400?
Yes 400
I think i am going to pick up the "T-hawk" what would be a good RC controller for it?
The T-Hawk includes a controller
If I were you BEFORE I bought ANYTHING I would do a little research if electrics are your thing then ezonemag.com is the place to learn about them they only do electric flight. It might be worth to you to pick up a couple of issues of Backyard flyer magazine if only for the reason that you will find many sources for planes that are "better" then the T-Hawk
