Set-up and flying tips
The CG range for the 52" Extra EXP starts at the front of the wing tube and
extends to the rear of the wing tube. There is plenty of room on the battery
tray to move your battery to achieve this CG location. Depending on your
flying style you can adjust the position of the battery to alter the CG to
accommodate your preferences. For this type of aircraft where I am going to
predominantly fly aggressive 3D I typically set the airplane up with a neutral
CG, meaning that when the aircraft is flown inverted straight and level it
requires no down elevator to maintain altitude. If your flying style leans more
toward precision aerobatics then I recommend setting your CG using the 45
degree line test. Fly the aircraft from left to right or right to left, whichever
direction you are more comfortable with at 3/4 to full throttle. Pull the
aircraft to a 45 degree up line and establish this line and immediately roll the
aircraft inverted. Establish this line and let go of the elevator stick. Ideally
the aircraft will continue to track on that 45 degree line for several hundred
feet before slowly starting to level off. Adjust the position of your battery to
achieve this flight condition. I also highly recommend taking the time to
properly set up your rates and exponential settings. Setting up low rates for
precision maneuvers and high rates for aggressive aerobatics and (continued)
