Devildog,
Yeah, sometimes the Mustang needs a bit of a "kick" to get those ponies moving.
UPDATE: I know EXACTLY why this is happening. Some engines are not sensitive to messing with power scalars, but others are. The P-51 Mustang is the latter.
To fix this and get those ponies moving, adjust the following numbers in the aircraft.cfg...
The original power_scalar in my FDG historical performance pack is set up for 0.95. Change this number to 1.00
[piston_engine]
power_scalar=1.00
cylinder_displacement=137.4
compression_ratio=6.0
number_of_cylinders=12
max_rated_rpm=3000.0
max_rated_hp=1450.0
fuel_metering_type=0
cooling_type=1
normalized_starter_torque=0.035
turbocharged=1
max_design_mp=60.999999
min_design_mp=1.0
critical_altitude=30000.0
emergency_boost_type=3
emergency_boost_mp_offset=6.1
emergency_boost_gain_offset=0.54
fuel_air_auto_mixture=0
auto_ignition=0
max_rpm_mechanical_efficiency_scalar=1.0
idle_rpm_mechanical_efficiency_scalar=1.0
max_rpm_friction_scalar=1.0
idle_rpm_friction_scalar=1.0
The original thrust_scalar is set up for 0.95. Change this number to 0.90
[propeller]
thrust_scalar=0.90
propeller_type=0
propeller_diameter=11.167
propeller_blades=3
propeller_moi=42.506502
beta_max=65.0
beta_min=15.0
min_gov_rpm=1200.0
prop_tc=0.010000
gear_reduction_ratio=2.38
fixed_pitch_beta=20.0
low_speed_theory_limit=80.0
prop_sync_available=0
prop_deice_available=0
prop_feathering_available=1
prop_auto_feathering_available=0
min_rpm_for_feather=500.0

power_absorbed_cf=0.0
defeathering_accumulators_available=0
prop_reverse_available=0.0

Your Packard-Merlin will be in full roar before ya know it. Sorry about my goof-up there!
