ArduCopter Release Notes:
------------------------------------------------------------------
ArduCopter 3.1-rc6 16-Nov-2013
Improvements over 3.1-rc5
1) Heli improvements:
a) support for direct drive tails (uses TAIL_TYPE and TAIL_SPEED parameters)
b) smooth main rotor ramp-up for those without external govenor (RSC_RAMP_TIME)
c) internal estimate of rotor speed configurable with RSC_RUNUP_TIME parameter to ensure rotor at top speed before starting missions
d) LAND_COL_MIN collective position used when landed (reduces chance copter will push too hard into the ground when landing or before starting missions)
e) reduced collective while in stabilize mode (STAB_COL_MIN, STAB_COL_MAX) for more precise throttle control
f) external gyro parameter range changed from 1000~2000 to 0~1000 (more consistent with other parameters)
g) dynamic flight detector switches on/off leaky-i term depending on copter speed
2) SingleCopter airframe support (contribution from Bill King)
3) Drift mode replaces TOY
4) MPU6k SPI bus speed decreased to 500khz after 4 errors
5) Safety improvements:
a) crash detector cuts motors if copter upside down for more than 2 seconds
b) INS (accel and gyro) health check in pre-arm checks
c) ARMING_CHECK allows turning on/off individual checks for baro, GPS, compass, parameters, board voltage, radio
d) detect Ublox GPS running at less than 5hz and resend configuration
e) GPSGlitch acceptable radius reduced to 5m (stricter detection of glitches)
f) range check roll, pitch input to ensure crazy radio values don't get through to stabilize controller
6) bug fixes:
a) missing throttle controller initialisation would mean Stabilize mode's throttle could be non-tilt-compensated
b) inertial nav baro and gps delay compensation fix (contribution from Neurocopter)
c) GPS failsafe was invoking LAND mode which still used GPS for horizontal control
