RC Joystick or Analog Deadband

Address:	^06
Access:	Read/Write
Effective:	After Reset or ^FF

This parameter configures the amount of joystick or potentiometer motion can take place around the center position without power being applied to the motors.

Bit	Definition		See pages
7:0	Values are for Joystick deadband		page 121
	0	= no deadband	or
	1	= 8%	page 131
	(2) = 16% (default)
	3	= 24%
	4	= 32%
	5	= 40%
	6	= 46%
	7	= 54%

Exponentiation on Channel 1 and Channel 2

Address:	^08 - Channel 1
	^09 - Channel 2
Access:	Read/Write
Effective:	Instantly

This parameter configures the transfer curve that is applied the input command.

Bit	Definition	See pages

7:0	(0) = Linear (no exponentiation - default)	page 122
	1 = strong exponential
	2 = normal exponential
	3 = normal logarithmic
