to be used. Before doing anything else to set up your model, first you must decide which MODEL TYPE best
fits your MULTIROTOR.
HELICOPTER SWASHPLATE TYPES:
The AT9 radios support 8 basic swash plate setups, including "single servo" (H-1-most helicopters use this
type) and 7 types of CCPM (cyclic and collective pitch mixing). A "single servo" swash plate 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 swash plate 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 swash
plate is off by 180 you will still use that swash plate 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.
