I've got another basic question regarding the throttle.  The throttle in the engine has a range of movement from the 8 O'clock position (toward the back of the plane to the 4 O'clock position (toward the front of the plane).  Remember, I haven't started the engine yet, so I'm just trying to get my bearings here.  Which direction is "throttle up" and which is "throttle down?"  Also, do I want the throttle in the 6 O'clock position while it's idling?

The engine is a Tower Hobby .4.

Thanks again everyone!
