roll. If not, adjust as needed to correct in
END POINT
: see p. 27.
Important note: prior to setting up throttle hold, idle-ups, offsets, etc, be sure to get your normal condition operating
properly.
Checking setup prior to going airborne: Check voltage! Then, with the assistance of an instructor, and having completed
all range checks, etc, gradually apply throttle until the helicopter becomes “light on the skids.” Adjust trims as needed to
correct for any roll, pitch, or yaw tendencies. If the tail “wags,” the gyro gain is too high. Decrease gyro gain.

HELICOPTER SWASHPLATE TYPES:
The
AT10
radios support 8 basic swashplate setups, including "single servo" (
H-1
-most helicopters use this type) and 7 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 7 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: HR3, 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
HR3
or
HN3
, except off by 180 degrees.
If your model's swashplate is off by
180 you will still use that swashplate type, but also use
SWASH AFR
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.
