RC Pit Spec: Setup & Lap Timer
Phone lap timing + AI coaching
Free · In‑App Purchases
Your whole RC pit, in one app.
RC Pit Spec brings your setups, lap times, AI analysis, parts, and sharing together in one place — the pit box in your pocket. Whatever you do at the track, just open the app and it's all there.
And the standout: your phone becomes a lap timer. No expensive timing gear — just point the camera to capture laps, then let AI analyze your runs and tell you what to tune next.
■ Lap timing with your phone
Point the camera at your finish line and it detects each pass automatically. Add ArUco markers to time multiple cars at once, scored by number. Mount it on a tripod and run pack after pack with no re-setup. Everything runs on-device — works even with no signal at the track.
■ AI causal analysis
Tap "analyze" and the AI compares this run to your last session at the same track: "Toe-in up front gave you better turn-in." Cause and effect, not guesswork. Apply a suggested change in one tap, then confirm on your next run whether it actually made you faster.
■ AI pit crew chat
Chat directly with a virtual veteran RC mechanic. Ask follow-ups, dig deeper, and get real coaching that respects your chassis' specific constraints.
■ Run log
Record date, track, surface, temperature, installed parts, and notes. See your progress in numbers and charts — the lap-trend graph drops as you get faster.
■ Garage
Manage all your cars and settings in one place, with a fast, low-typing UI built for the pit lane.
■ Parts management
Track your inventory, what's installed on which car, and maintenance reminders.
■ Pit Lane
Browse, compare, and import other drivers' setups. Learn from the fast guys and share your own.
■ PDF export (Tamiya chassis)
For TT-02, MB-01, TRF421 and TA08R, export an official-style setup sheet to print and keep in your pit box.
■ Supported chassis
47 chassis across touring, off-road, drift, and Mini-Z — including Tamiya, Kyosho, YOKOMO, XRAY, Team Associated, Mugen, Infinity, Schumacher, and more. New chassis added regularly.
■ Pricing
Free to start. Optional Basic / Pro plans for AI usage and premium features.
