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.

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.

5.2.2 SWASH AFR (not in SWH1):

 

Except SWASH PLATE, function menu of helicopter is same as GLID/ ACRO. Please find the former instructions.

Swash plate function rate settings (SWASH AFR) reduce/increase/reverse the rate (travel) of the aileron, elevator (except H-2) and collective pitch functions, adjusting or reversing the motion of all servos involved in that function, only when using that function. Since these types utilize multiple servos together to create the controls, simply adjusting a servo's REVERSE or END POINT would not properly correct the travel of any one control. Since H-1 uses one servo for each function, there is no need for AFR in H-1.

Since aileron always uses no more than 2 servos, check it first. Either both operate properly (no change needed), both operate backwards (reverse the whole function), or one servo operates backwards (reverse that servo alone). Next check elevator. Remember, the aileron servo(s) operate correctly, so if elevator does not, we should only have 2 choices left—the whole function needs to be reversed, or the servo(s) not shared with aileron need to be reversed. If aileron and elevator are not working properly, the only thing that could be wrong is the whole direction collective operates (reverse the whole function). In our example, HR3 is 180 degrees off from the swash plate of the Caliber. Therefore, it is very likely that several functions will not operate properly. The collective pitch operation is backwards; but reversing all three servos would also reverse the aileron and elevator operations. Changing the collective pitch rate, however, from +50% to -50%, will reverse the collective pitch without affecting the aileron action.

 

 

Checking For Proper Motion On An HR3 Swashplate
HR3 SwashType	Proper Motion	Wrong Motion	How to Fix
AILERON STICK.		Swashplate tilts left.	Reverse AIL setting in SWASH to -50%.
Swashplate tilts right.	Back of Swashplate moves up.	Ch6 servo moves incorrectly; REVERSE.
	Back of Swashplate moves down.	Ch1 servo moves incorrectly; REVERSE.
ELEVATOR STICK.	Front of swash plate moves down;	Swashplate moves the opposite.	Reverse ELE setting in SWASH. (ex: +50 to -50)
back of swashplate moves up.	Entire swashplate moves up.	Ch2 servo moves incorrectly; REVERSE.
RUDDER STICK.	The leading edges of tail blades rotate left.	Blades rotated right.	REVERSE the rudder servo.
THROTTLE STICK.	Entire Swashplate lifts.	Swashplate lowers.	Reverse PIT setting in SWASH.
