E-flite Sobré 3D Profile Assembly Manual
Control Throws
Turn on the transmitter and receiver of your Sobré. Check
the movement of the rudder, elevator and ailerons using the
transmitter. Reverse the direction of the servos at the transmitter
if necessary.
Use a ruler to adjust the throw of the elevator, ailerons and
rudder. Adjust the position of the pushrod at the control horn to
achieve the following measurements when moving the sticks to
their endpoints.
Measurements are taken at the widest point on the surface.

These are general guidelines measured from our own flight tests
and those of Jon Leyland. You can experiment with higher rates to
match your preferred style of flying.

Note: George Hicks' recommended 3D throws should
be considered for advanced pilots only. George uses the
E-Flite 3D arms with the connecter all the way out (last
hole-most throw). He uses the lowest hole over the hinge
line at the control surface on all surfaces.
