WHOA!!![X(] That's a heck of a plane for a beginner. I don't see a happy ending with that.
Please reconsider getting a trainer first, master it, then move up to this one.
AND NEVER EVER TURN OFF THE TX FIRST!!!!!!! FIRST ON/LAST OFF ALWAYS!!!!
Anyhow, you need to reverse the throttle channel on your tx, that will get the throttle going the correct direction.
As for the throws, #1 it's a fast mover, it will not need a lot of throw to maneuver.
If you need to have more, simply move the control rod to the hole closest to the hinge line on the control horn.
Please, again this is not a first timer bird. Reconsider your choice for a first bird.
