We're using a creating a rocket and we're having an issue with the radius. The stability is also way off as well. I've attached the output as a txt file since there's a character limit. Any help would be much appreciated

config.py
sustainer_po_cd, sustainer_poff_cd, sustainer_cp = parse_rasaero_file(join(this_dir, "data", "sustainer.CSV"))
SUSTAINER_PARAMS = {
"radius": 0.057/2,
"mass": 1.687, # airframe mass
"inertia": (645548/(110**9), # x
229864458/(1109),# y
229883464/(1*109) # z
), # Just airframe
"coordinate_system_orientation": "nose_to_tail",
"center_of_mass_without_motor": 0.829,
"power_on_drag": sustainer_po_cd,
"power_off_drag": sustainer_poff_cd,
"center_of_pressure_source": sustainer_cp
}

sustainer.py
from lura_rockets.G2_DART.CDR import config
from lura_rockets.supersonic_rocket import SupersonicRocket

===== ROCKET =====

dart = SupersonicRocket(**config.SUSTAINER_PARAMS)

===== PARACHUTE =====

main_parachute = dart.add_parachute(**config.SUSTAINER_MAIN_PARACHUTE, sampling_rate=100)
drogue_parachute = dart.add_parachute(**config.SUSTAINER_DROGUE_PARACHUTE)

dart.all_info()

Expected behavior

Fixed this. Rockets are required to have atleast one aero surface otherwise the loop in
rocketpy/plots/rocket_plots.py
in the function
_draw_tubes
exits prematurely and therefore the return value
radius
has not been defined

We should allow the draw method to work properly even if no aerosurface is provided. Thanks for opening this question!

Additional context

Should be quite easy to solve the problem.
