This should allow single copter's MOT_ parameter descriptions to be more
easily recognised as belonging to SingleCopter when viewed on the wiki's
arducopter-parameters page
Setting the GPS Failsafe to LAND_EVEN_STABILIZE means the copter will
LAND if it loses GPS even if it's in a manual flight mode like
Stabilize. With this setting it makes sense to check the GPS quality
before arming even if we're in stabilize mode.
When GPS message is late by 100ms or we are glitching, degrade the GPS
vs inertial nav position error to 10% over 2 seconds instead of
immediately setting it to zero. This avoids jumpy position estimates
when the GPS misses an update
this will allow for reverse in steering mode, while also fixing a
problem with AHRS yaw when reversing, and a problem with initial
throttle in steering mode
FS_GPS_ENABLE parameter accepts two new options, 2=AltHold,
3=LandEvenFromStabilize.
If set to 3 the GPS failsafe will trigger and LAND even from manual
flight modes like Stabilize and ACRO. This is useful for users who want
to ensure their copters can never stray outside the circular fence (the
fence only triggers when it knows it is outside the bounds, and it can't
know this if it has no GPS)
Rewrote tail and main rotor ramp up methods
Moved direct drive ESC speed control into rsc_control method
Pass in ch7 servo as servo_aux to TradHeli motors object constructor
split CH7_SETPOINT parameter into GYR_GAIN and DIRECTDRIVE parameters
replaced RSC_RATE with uint8_t RSC_RAMP_TIME parameter
rename GOV_SETPOINT parameter to RSC_SETPOINT
RSC_MODE parameter description updated to indicate it controls the
source of main rotor speed
Repurposed external gyro and made it multi-funcitonal.
required PWM on Ch8 to start the motor in RSC Mode moved up from 100 to 400. This is to facilitate two-stage switching of the motors with PWM>100 starting the tail motor, and PWM>400 starting the main motor.
