Race-Day Drone Checklist and Pit Procedures for Consistent Finishes

Consistent preflight routines and a stocked pit table reduce stress and improve finishing rates at drone races. Racers and pit crews who adopt a short, repeatable walk-through before every heat are more likely to complete heats and recover quickly from minor damage. This report condenses practical hardware, software, and operational priorities designed for race-day reliability.

Start with hardware basics: carry two sets of matched props per quad and inspect blades for chips or cracks; balance props if vibration appears. Bring at least 3–4 charged race packs per quad, stored at safe voltage, labeled with cycle counts, and kept in a LiPo-safe bag with a high-quality charger. Finger-check motor shafts for play, torque motor mounting screws and use thread-lock on frequently loosening screws, and inspect solder joints and connectors such as XT60 and XT30. Confirm VTX and diversity antenna health and carry spares for SMA and RP-SMA connectors. Verify the flight controller and Betaflight firmware are flashed and configured for the race battery—4S versus 6S—and back up configs to a thumb drive or cloud before arrival. Plan to bring 10–20 spare props; different venues can favor different prop sizes.

On the software side, perform a receiver check by arming briefly, checking stick directions, and testing RSSI. Recalibrate the accelerometer if the frame has been opened and confirm level for launch. Use a tuned PID and rate baseline appropriate for the track style; save experimental tweaks for practice sessions rather than minutes before a heat. Test throttle failsafe, GPS or home functions if fitted, and beeper or LED locator functions. Confirm video feed frequency and channel with race control and set VTX power to the event limits to avoid conflicts.

Pit procedures should be fast and repeatable. Assign a small table area, keep tools organized, and use a marked spot for each quad. For quick triage, replace props and battery, spin props briefly to confirm motor direction and look for vibration. If vibration persists after prop swaps, consider swapping motors or accepting a DNF if structural issues remain. Check battery voltage under load when behavior seems unusual and do not drain race packs below safe cutoff. For cold venues, pre-heat motors by spinning props at low throttle to warm bearings.

Tuning pointers focus on stability and responsiveness: start with conservative filtering to reduce oscillations, use known-good base PIDs for your frame and prop combination, and retune around accel and derivative terms when changing prop size or voltage. Use Blackbox logs after crashes or oscillations to identify problem frequencies.

Post-race workflow includes changing props, checking screws, swapping batteries to cooldown, and writing one-line notes after each heat to speed later troubleshooting. Verify compliance with local event rules and national UAS regulations, use spotters when required, respect crowd lines and netting, and never retrieve a drone from a roadway or restricted area without staff permission.

Pack quads and props, 4+ charged batteries, radio with spare batteries, tools including hex drivers and Loctite, spare VTX antennas, charger and cables, goggles and video cables, tape, marker, spare screws and motor wires, a first-aid kit and LiPo bag. Prioritize simple, repeatable checks and keep spares for the most failure-prone parts to maximize the chance of staying in the race.
