RADIO SETUP
Your RotorScale 450 helicopter requires a Flybarless Flight Controller. See
Flight Controllers. Refer to your selected Flight Controller’s instruction manual for setup. For a basic we
recommend the Tarot ZYXS2 3-Axis Flight Controller. Download the Setup and Software Guides online here.
PROGRAM A THROTTLE CUT SWITCH
As an additional safety precaution, we recommend that pilots program a switch on their radio transmitter to act as
a Throttle Cut. Best practices includes always toggling the Throttle Cut manually on your radio whenever the model
is powered on but you are not actually flying it. Be vigilant to avoid accidental spinning of the rotor blades.
PROGRAM DUAL RATES AND EXPONENTIAL (“EXPO”)
If desired, you may program Dual Rates and Expo However, we recommend limiting the highest Expo value to less
than 50. As a Sport Scale helicopter, set mild throws and exponential. Avoid excessive throws or sudden and
severe control inputs that may damage your helicopter. Due to the heavier weight and fiberglass fuselage, flying a
RotorScale 450 helicopter is intended to be more realistic and less aggressive than flying aerobatic 3D helicopters.
BINDING THE RECEIVER
Follow the normal bind procedure for your selected radio transmitter and receiver. A special bind process is not
required, however as with any RC model, please be mindful of potential Throttle channel reversing.
CONTROL DIRECTION AND POTENTIAL CHANNEL REVERSING
Observe the model’s response to your stick inputs and reverse the servo in your radio settings menu if required.
1. Pushing the elevator stick away from you should dip the swashplate down toward the model’s nose.
2. Pulling the elevator stick toward you should dip the swashplate down toward model’s tail.
3. Moving the aileron stick to the right should dip the swashplate down toward the right side of the
helicopter (as if sitting inside the helicopter).
4. Moving the aileron stick to the left should dip the swashplate down toward the left side of the helicopter
(as if sitting inside the helicopter).
5. Moving the rudder stick to the left should twist the tail rotor blades with the trailing edge facing the left
side of the helicopter.
6. Moving the rudder stick to the right should twist the tail rotor blades with the trailing edge facing the
right side of the helicopter.
SETTING EXPECTATIONS: FLIGHT CHARACTER AND FLYING TIPS
Different Flybarless Flight Controllers offer different features. Simpler variations do not feature recovery modes or
auto-leveling modes. Regardless of which flight controller you choose to install in your RotorScale helicopter, it is
important to “fly two steps ahead” of the model at all times. For example, if a pilot puts their helicopter into a
slow and level forward motion then releases the control sticks, the helicopter will continue to drift forward but at a
decreasing speed until all that forward momentum is depleted and/or environmental conditions counteract that
