ROADSTER MODELS — Lift module experiment record, draft 01
Purpose: compare the same propulsion module with open inlet, duct and body.
Status: PLANNED TEST. Blank fields are not measurements or acceptance evidence.

BEFORE POWER
[ ] Review rotor retention, fixture and guard; keep personnel outside rotor plane.
[ ] Verify thrust sign and measurement range with known reference loads.
[ ] Verify independent shutdown and low-energy initial control checks.
[ ] Record installed module mass including inlet, duct, guard, ESC and wiring.
[ ] Select test points and repeat count before collecting comparison data.
[ ] Define permitted hardware temperature and electrical limits from real datasheets.

CONFIGURATIONS (keep all other parts identical)
A — open inlet reference, same outlet guard.
B — inlet grille + curved duct, same module and outlet guard.
C — installed body section, controlled ground clearance.
Separate matched-RPM comparisons from matched-electrical-power comparisons.

ONE RECORD PER TEST POINT / REPEAT
Configuration / repeat / commanded throttle / elapsed time:
Loaded voltage V / current A / electrical power W (= V x A):
RPM / net vertical force N / uncertainty N:
Motor, ESC and battery temperatures / measurement locations:
Clearance mm / ambient conditions / vibration observation:
Stable sampling interval and raw-log filename:
Shutdown reason or anomalies (never discard without documenting):

ANALYSIS
Mean and spread across repeats, including failed/aborted runs:
Installed thrust ratio = B or C net force / A net force at matched conditions.
Compare net force per electrical watt and temperature rise versus elapsed time.
Plot net force versus ground clearance. Check recirculation visually with a
non-intrusive method; do not infer pressure or thermal behavior from animation.
Publish actual results, raw logs, photos and uncertainty together.

RELEASE REVIEW
[ ] No mechanical damage, slipping, rotor contact or unresolved control polarity.
[ ] Approved electrical and thermal limits maintained throughout each run.
[ ] Results repeatable within declared instrument and test uncertainty.
[ ] Duct and guard losses measured; installed mass entered into the vehicle budget.
[ ] Review unresolved failures before a four-module rig is approved.
Single-module testing does not validate total vehicle lift, control stability,
near-ground interactions or 60-second free hover. Those require separate tests.
