SETUP INFORMATION
Center of Gravity -
Velox VR-1
Edge 540
These are starting, aerobatic center-of-gravity locations. After several flights, you can and should adjust
in small increments to find your perfect, personal CG location.
Control throws, high and low rate –
Low/Precision Rates (in degrees and inches) and Corresponding Exponential
Aileron
Elevator
Rudder
High/3D Rates (in degrees and inches) and Corresponding Exponential
Aileron
Elevator
Rudder
The above throw measurements are taken at the aft edge of the ailerons and elevator,
and from the bottom aft edge of the rudder. Note that Hitec and Futaba radios require
NEGATIVE exponential, while JR and Spektrum use POSITIVE exponential.
Servo arm length:
Most servo arms have multiple locations which you can install your pushrod adjustors into, giving different
effective servo arm lengths. The method to determine the correct hole is as follows:
Set your high-rate throws as indicated above using the endpoint adjustment for each channel in your
transmitter. If your endpoint adjustment is near maximum (a value of 140-150 on most transmitters) then
you are using the correct hole. However, if your endpoint adjustment is much lower, under 125 for
example, you may need to use a hole that gives a shorter effective arm length. If your endpoint
adjustment for correct high-rate throws is excessively low, you will notice very poor servo performance.
To put it simply, use the shortest arm length that still allows proper high rate throws.
Once you are certain of the correct arm length, be sure to use thick CA to lock all of your adjustor nuts on
all servo arms.
