Control Throws - Carf-Models Extra 330sc Assembly Manual

C of G and Control Throws
The centre of gravity position of the Extra 330SC is 90mm to 100mm from the leading edge of the wing at the tip. Pick-
ing the completed model up at the tips will not harm the airframe, but due care should be taken in the method you use.
Do not use any pointed implements to hold the model up, you may penetrate or damage the fuselage or wing struc-
ture. It s quite simple to have someone give you a hand, and using your fingers carefully lift the model at the C of G
points you have measured.

Control throws:

This is another area, where your personal preferences are going to determine what you actually need. We have listed
below what we believe is a good starting point. From there on you can fine tune your Extra 330SC to suit your require-
ments.
The Extra 330SC has a top skin hinge system, and as such it needs reverse differential, that is you will need more
down travel than up! The reason for this is, as the aileron goes down, it actual looses area volume, part of the aileron
disappears into the wing, decreasing the amount of surface area exposed to airflow. A good principle to work with is to
give your aileron 10mm more down at full rates. Although at full rates the roll rate will be blistering, as you move into
low or mid rates the preset differential will become more evident. Obviously you can use your transmitters differential
settings if it is capable of doing so, just remember this type of differential is reverse to what is considered normal.
