HELI-SPECIFIC BASIC MENU FUNCTIONS
MODEL TYPE: This function of the PARAMETER submenu is used to select the type of model programming to be used.
Before doing anything else to set up your model, first you must decide which MODEL TYPE best fits your aircraft. If
your transmitter is a 9CA super, the default is ACRO. If it is a 9CH super, the default is HELI(SW1).
HELICOPTER SWASHPLATE TYPES:
The 9C super radios support 6 basic swashplate setups, including "single servo" (SW1-most helicopters use this type) and
5 types of CCPM (cyclic and collective pitch mixing). A "single servo" swashplate uses one servo for each axis: aileron,
elevator (cyclic pitch), and collective pitch. CCPM helicopters utilize a combination of servos working together to achieve
the 3 axes of motion. There are 5 basic CCPM types, displayed below. CCPM has several advantages, the most obvious
of which is far less mechanical complexity to properly move the swashplate of the helicopter. Additionally, several servos
working in unison (ex: SR3, all 3 servos together create elevator movement) dramatically increases the torque available as
well as the precision and centering.
Please note that some helicopters are type SR-3 or SN-3, except off by 180 degrees. For example, the Kyosho ® Caliber ™ is
SR-3 but with the 2 parallel servos to the rear of the helicopter, not front. If your model's swashplate is off by 180 degrees,
you will still use that swashplate type, but also use SWASH AFR(p.84) to adjust the functions as needed until it operates
properly. Additionally, different angles of CCPM may also be created utilizing the fully assignable programmable mixes.
(See our Frequently Asked Questions area at www.futaba-rc.com\faq\faq-9c.html for specific examples.)
Not operating quite like you expected? In many CCPM installations you need to either reverse the direction of a specific
function (SWASH AFR) or reverse a single servoís direction (REVERSE). See SWASH AFR for details. (p.84)
Swashplate Type
s
HELISWH1 Type: Independent aileron, pitch and elevator servos linked to the
swashplate. Most kits are HELISWH1 type.
HELI SWH2 Type: pushrods positioned as shown. Elevator operates with a mechanical
linkage. With Aileron inputs, the aileron and pitch servos tilt the swashplate left and
right; with Pitch inputs, the aileron and pitch servos raise the swashplate up and down.
HELI SWH4 Type: pushrods positioned as shown. With Aileron inputs, the aileron and
pitch servos tilt the swashplate left and right; with Elevator inputs, the servos tilt the
swashplate fore and aft; with Pitch inputs, all four servos raise the swashplate up and down.
HELI SR-3 Type: pushrods positioned as shown. With Aileron inputs, the aileron and
pitch servos tilt the swashplate left and right; with Elevator inputs, the three servos tilt
the swashplate fore and aft; with Pitch inputs, all three servos raise the swashplate up
and down.
HELI SN-3 Type: pushrods positioned as shown. With Aileron inputs, the three servos
tilt the swashplate left and right; with Elevator inputs, the elevator and pitch servos tilt
the swashplate fore and aft; with Pitch inputs, all three servos raise the swashplate up
and down.

HELI SR-3s Type: pushrods positioned as shown. Fundamentally, the servo operations
of SR-3s type are almost same as SR-3 type.
However, the servo arrangement about elevator operation differs.
