Randy Mackay a9f1a2ee5e Copter: disarm on land even if pilot throttle not zero 
default behaviour remains as before, this is an compile time option only
 2014-01-15 11:31:00 +09:00
Randy Mackay df9d1614e2 Copter: remove PID logging 
Almost never used and eats up limited log description space

Randy Mackay 81fc24586e TradHeli: remove calls to get_manual_collective in auto throttle 
set_collective_for_landing method makes this unnecessary
 2013-11-15 22:58:36 +09:00
Randy Mackay 60bc9f4539 TradHeli: angle error to zero while motors runup 
Set angle error to zero in get_roll_rate_stabilized_bf,
get_pitch_rate_stabillize_bf, get_yaw_rate_stabilized_bf.

Robert Lefebvre 9ae66c1773 TradHeli: add support for drive tail rotors 
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.

Randy Mackay 8f2c9591ff TradHeli: dynamic_flight flag based on inertial nav speed 
Created new heli.pde for heli_integrated_swash and check_dynamic_flight

Randy Mackay f5b1114aea Copter: range check pilot requested lean angles 
This fixes a bug uncovered by MHA in which the receiver output 900 pwm
for roll and pitch to the APM which was interpreted as requesting an 80
deg lean angle which the copter then attempted to do!
 2013-11-13 14:21:21 +09:00
Randy Mackay f29f7d9777 Copter: bug fix to take-off in Loiter and AltHold 
Always set the target altitude after take-off to be current altitude +
20cm.  This resolves a bug in which the target altitude could end up
being a couple of meters higher than the current altitude if the user
entered Loiter / Alt Hold mode before inertial nav altitude estimate had
settled.

Randy Mackay 653a5036ae Copter: #define for initial altitude jump during take-off 
Developers can add a line like to APM_Config.h to reduce the initial
jump when taking off in Loiter or AltHold flightmodes:
#define ALT_HOLD_TAKEOFF_JUMP 0

Randy Mackay 2696e160e6 Copter: surface tracking improvement 
Separate correction speeds for pilot input vs altitude-above-ground
errors to allow slower correction to sonar signals.
Change SONAR_GAIN parameter to be altitude error -> desired speed.  This
means it should be set 10x larger than before.
Replace hard-coded sonar cut-off percentage of 70% with
SONAR_RELIABLE_DISTANCE_PCT.
Reduce sonar cut-off percentage to 60%.
Add desired sonar altitude to dataflash log's CTUN message.

Randy Mackay 9672742b42 Copter: bug fix to look_ahead_yaw 
Fix received from David Dewey
Was incorrectly using the direction instead of heading when deciding
whether to point forward or not.  Reduced YAW_LOOK_AHEAD_MIN_SPEED to
1m/s because bug meant it was nearly always pointing forward and 10m/s
(the old value) seemed too high

The motors_runup_complete must be a feature that Rob has implemented in
his clone which has not yet reached master.  We will need to restore
these lost few trad-heli specific lines once Rob's changes make it to
master.
