initialised_ok was being set to false when frame/class was set as the
method was not overridden and thus Heli's set_frame_and_class was
setting initialised_ok to false. When the init_output method was called
it would be unconditionally reset to true.
this converts the heli code to use the SRV_Channels output
functions. It does not change behaviour, but removes the last vehicle
type that did its own servo output calculations. This change also
fixed servo initialization conflicts.
Note that this also allows helis to be setup with more than one
channel for a particular output (eg. two separate channels for tail
servo if they are wanted). This isn't likely to be used much, but does
make heli consistent with other vehicle types
Change to ramp and runup DDVP tail rotor to prevent torque pitching the frame and provide runup in sync with main
rotor like a mechanically driven tail.
Fix some comments and remove indents found in whitespace in AP_MotorsHeli.cpp and AP_MotorsHeli.h
AP_MOTORS_x_FRAME definitions moved to motor_frame_type enum
init function and now accepts frame-class and type to perform initial motor setup
set_frame_class_and_type allows real-time changing of motor setup
initialised_ok flag and accessor records whether setup was successful
this gives more control over throttle for petrol
helis. H_RSC_POWER_NEGC allows for a asymmetric V-curve, which allows
for less power being put into the head when landing or when sitting on
the ground. That can lead to significantly less vibration and chance
of ground oscillation. A heli not being flown with aerobatics does not
need to use high throttle at negative collective pitch.
The H_RSC_SLEWRATE allows for a maximum throttle slew rate to be
set. Some petrol motors can cut if the throttle is moved too
quickly. We had this happen at a height of 6m when switching from
ALT_HOLD to STABILIZE mode. It also lowers the chance of the blades
skewing in their holders with the sudden change of power when the heli
is disarmed. In general it is a bad idea to do instantaneous large
movements of a IC engine throttle.
