User Manual

It is important that the airplane is right-side up and stationary when the aircraft is
powered up. That position will be recorded in the Vector as “Straight and Level” flight
attitude, which determines flight recovery in Stability Mode and neutral attitude in
Optimized Mode. You must have the plane right-side up level and stationary, every
time you power up the plane.
Selecting a 3-Position Switch PWM (Spektrum type) Transmitter
Switch for your Vector
The Arrows Bigfoot RTF is equipped with a transmitter with a 3-position switch for all
three Vector modes. On other Arrows planes, the default is 2-positions. If left on a 2-
position switch the Vector will provide both the Stability Mode and the Optimized Mode
as the two positions capable of being selected, without an OFF Mode position. In order
to have all three Vector Mode positions, including OFF, you must select a 3-position
switch through Transmitter Programming on your computerized PWM transmitter.
Before Flying
Always do a control check to see that the controls are operating in the correct position.
Refer to your Model’s manual.
With the Vector activated, test the Vector on each of the available modes, and confirm
that the Vector’s response is in the correct direction.
For example:
1) If you raise the right wing the Vector response will be to move the right aileron up
to counteract the raising of the wing.
2) In Stability Mode, the right aileron will stay in the up position when the right wing
is raised.
3) In Optimized Mode, the right aileron will go back down towards a neutral position
if the wing is still raised.
4) In the Off Mode, the Ailerons will not react if the right wing is raised indicating the
Vector is not engaged.
5) Test the Rudder and Elevator correction responses with a similar method. Just
because they move does not mean they are moving in the right direction. Verify.
Note: The flaps and LEDs are not at all part of the Vector system. The flaps are
plugged right into the receiver with the included Y-harness.
