Expo duo -
exponential control system
Expo duo provides the benefits of
exponential control to hobbyists that do not have sophisticated radios
with built in exponential functionality.
Expo duo can decrease the sensitivity around the center position,
making it easier for new flyers to control their models, or it can
increase sensitivity for experienced users who want to do aerial
Expo duo works by intercepting servo pulses from your receiver,
processing them with a mathematical algorithm, then outputting new
servo pulses according to your desired response. You can set the
desired sensitivity level with the onboard dial. The result is that
small stick movements around the center point will cause smaller, or
larger movements on the servos.
As a bonus feature, Expo duo will reject invalid servo pulses, which
will filter out many glitches.
Expo duo works great with Blade CX/Lama 2 helicopters,
flying wings and other dual servo systems.
Expo duo can also be used to add exponential control to
a single servo - just leave the other channel unconnected.
There is an incompatibility
problem with Expo duo and Blade CX2 helicopters. Use of Expo Duo with a
Blade CX2 is not recommended.
