An optional engine can be defined if the aircraft you are modelling is a motorglider or a towplane.

The mathematical engine model is based on a 4-stroke non-turbocharged engine.

This is an engine.dat example:

# Propeller/engine position
position        = [ 1.50 0.0 0.0 ]

# Motor cowling drag
cd              = 0.10
ref_area        = 1.0

# Nominal power [W]
power           = 69000.0
rpm             = 5100.0
rpm_max         = 5800.0

# Propeller data
prop_diameter   = 1.615
prop_pitch      = 85.0
prop_chord      = 0.4
prop_cd         = 0.02
prop_blades     = 2
prop_gear_ratio = 2.43

# Show more data on the HUD
debug = true

If you want more information on the HUD while fine-tuning the engine, set the debug = true option. You can remove this again before you release your model to the public.
