It is essential that Edge 540 be properly balanced before any
attempt is made to fly the aircraft. Don’t inadvertently neglect this
step. The recommended C.G. (Center of Gravity) location for the
first flights with the Edge 540 is 4

'' from the leading
edge of the wing, measured at the fuselage.
Mount the receiver battery inside the top of the motor box. If
necessary, add weight to either the tail or nose until the correct
balance is achieved. Stick-on weights are available at your local
hobby shop and work well for this purpose.
The following control throws offer a good place to start with for
your first flights.
Set up the control throws for a standard rate for the first few
flights, then increase the throws to your liking.
The 3-D rates allow the Edge 540 to perform the new generation
of aerobatic maneuvers, such as waterfalls, elevators and
harriers. However, they also make the model very sensitive. It is
recommended that the 3-D rates be tried only after becoming
familiar with your Edge 540.
Section 19: Balancing the Edge 540
Section. 20: Control Throw Recommendations
When using 3-D rates, use 70% expo on elevators to keep the
model controllable. Also be sure that adequate mechanical
advantage is maintained when adjusting the elevator linkages for
3-D rates or flutter can occur.
