RC Speed Calculator Pro vs RC Pit Crew

Also try RC Speed Run to log and share your fastest runs! https://www.sodialed.com/apps/rc-speed-run Quickly and easily get an estimate for your RC car's top speed with RC Speed Calculator Pro! Just tell us which car you have, enter some info about your gearing, motor and batteries, and we'll do the rest. Record your estimates to compare different car setups, and if you have a speed gun, you can record your actual top speed along with the estimate. Info you'll need: - Pinion gear teeth - Battery cells (or voltage) - Motor Kv rating - Tire diameter (we can fill this in based on your car type) Info we probably have already based on your car: - Spur gear teeth - Transmission ratio Please note, our top speed estimates are just that - estimates! We use a formula that works in theory (in perfect, not real-world conditions), but every car and all driving conditions are different, so expect some variation from real measured speeds.

Your RC car's acting up. This tells you why, fast. Pick what it's doing and get the likeliest cause first, ranked by how often it's the real culprit, with the exact checks to run. Built by a basher, for bashers. No login, no fluff, works fully offline at the track. What's inside: Symptom diagnoser: 18 common problems and 80+ ranked causes, from pulling to one side to cutting out at speed to no reverse. Pick your symptom, answer one follow-up, and get the fixes in order of likelihood. Gearing calculator: a live heat gauge that shows when a pinion swap is safe and when you're heading for meltdown. Watch top speed, RPM, and rollout move as you dial it in. Reverse gearing finder: tell it the top speed you want, it tells you the exact pinion to fit, and warns you if it'll run hot. Scale speed converter: turns your real mph into true scale speed, the number that makes non-RC people's jaws hit the floor. Every cause is grounded in real RC forum threads and years of wrenching, not guesswork. From the RC Pit Crew channel by Shalgum.
