RC Car & Battery Tracker - Pit

New: Track LiPo health, save setup sheets per track, and calculate gear ratios at the pit table.

Pit is the complete pit table app for RC enthusiasts. Manage every vehicle with full build specs, save setup sheets per track and condition, track LiPo battery health, log session lap times, and calculate gear ratios instantly. Whether you race competitively or bash on weekends, Pit keeps every setup, battery, and session organized and ready.

VEHICLE MANAGEMENT

• Store full build specs: motor, ESC, gearing, suspension, diffs, tires, electronics, and body
• Attach photos to each vehicle profile
• Track runtime hours per vehicle for maintenance scheduling
• Fleet status at a glance: Ready, Maintenance Due, or Needs Repair
• Filter and search your entire fleet instantly

SETUP SHEETS - THE CORE FEATURE

• Save complete suspension and gearing setups per track and condition
• Load any saved setup instantly at the track - no more rewriting from scratch
• Duplicate and modify setups in seconds (the primary workflow for competitive racers)
• Attach performance notes: what worked, what to change next time
• Rate each setup 1-10 after a run

SESSION LOGGING

• Log every run: vehicle, setup used, location, and session type
• Enter lap times manually or paste from timing systems
• Track motor temp, ESC temp, and ambient temperature
• Record race results: qualifying position, finish position, rounds completed
• Link the battery used and track voltage from start to finish
• Runtime minutes auto-accumulate for maintenance hour tracking

BATTERY MANAGER

• Full profile for every LiPo, LiHV, LiFe, and NiMH pack
• Track cycle count and physical condition per battery
• Log internal resistance per cell over time - rising IR means degrading health
• Puff warnings front and center: slight, moderate, and severe alerts
• Automatic warnings when a LiPo has been fully charged for too long
• Retirement tracking with safe disposal reminders
• Bundled LiPo safety reference covering charging, storage, puffing, and thermal runaway

GEARING CALCULATOR

• Enter spur and pinion tooth counts for instant gear ratio calculation
• Final Drive Ratio (FDR) computed with your internal transmission ratio
• Estimated rollout and top speed with motor KV and tire diameter inputs
• Direction guidance: going up 2T on the pinion increases top speed but raises motor temp - Pit tells you what to watch
• Bundled gear ratio reference by vehicle class

MAINTENANCE TRACKING

• Log every service: bearing service, diff rebuild, shock rebuild, spur replacement, and more
• Runtime hours since last service auto-calculated from session logs
• Upcoming maintenance alerts based on your service intervals
• Parts used, cost, and next service interval per log entry
