
After increasing the control response/authority and installing the short length
stabilizer flybar (as previously outlined in this section) many pilots will be able to fly
the Evolve 300 CX successfully in winds up to 5mph. However, we do not recommend
that all pilots fly in winds up to 10mph, especially first ‐ time and low ‐ time pilots, as
more experience is typically required to maneuver/fly the helicopter successfully in the
higher speed/stronger winds. Also, we do not recommend attempting to fly the Evolve
300 CX in any winds higher speed/stronger than 10mph.

When flying outdoors in the wind it’s recommended to raise the throttle trim to the
middle or even the highest possible position in order to increase the maximum amount
of power available when the throttle stick is raised to the highest possible position.
IMPORTANT NOTE: If you do raise the throttle trim lever you MUST remember to
lower it AND the throttle stick to their lowest possible positions IMMEDIATELY in the
event of a crash or rotor blade strike. Failure to lower the throttle trim and throttle
stick to their lowest possible positions immediately in the event of a crash/rotor
blade strike can result in damage to the ESCs in the 3 ‐ in ‐ 1 control unit (which may
require replacement of the control unit).

Although the Evolve 300 CX is larger and more capable of flying outdoors in wind than
most other CX (coaxial) helicopter models, there are some traits inherent due to the
coaxial and fixed ‐ pitch design that pilots should always keep in mind. Also, it will take
some practice for most pilots, even those with experience flying FP (fixed ‐ pitch) and CP
(collective ‐ pitch) helicopters, to identify and better understand all of these traits but
here are the most important ones to keep in mind:
o
Due to the fixed ‐ pitch rotor blade design most pilots will find that it takes some
‘balancing’ of the throttle/power output and the ‘angle’ the helicopter is
pitched/banked at to maintain speed and altitude during
forward/backward/sideways flight. This is especially true when flying directly
into the wind, and in some cases it will not be possible to fly directly
into/penetrate the wind at a reasonable ground speed without gaining altitude
(this trait is also inherent in most single ‐ rotor FP helicopters).
o
Also due to the fixed ‐ pitch rotor blade design it will take some practice to find
the best balance of throttle/power output and other controls to descend/lose
altitude without decreasing the speed/RPMs of the rotor blades too much (if
the speed/RPMs decrease too much the helicopter can lose altitude too quickly
and/or become unstable resulting in a crash). This is especially true when trying
to descend/lose altitude and when flying into (upwind), with (downwind) or
even sideways in the wind (this trait is also inherent in most single ‐ rotor FP
helicopters).
