🧰 Maintenance & Safety

🧰 After-Run Drying

Getting all the water out of a model straight after a wet run, before it is put away.

Blow the chassis out with low-pressure air or a leaf blower, remove the battery, dry the motor by running it briefly with the wheels off the ground, then re-oil bearings and hinge pins. Rust and seized bearings come from letting it sit damp overnight.

What it actually does

Water left inside a model does its damage over the following days, not during the run. Bearings rust, screws seize, and metal gears pit. Ten minutes of drying after a wet session is the difference between a car that lasts and one that seizes solid in the cupboard.

In practice

Get the body off, blow out the standing water with compressed air or a leaf blower, remove the battery, and let the chassis dry properly somewhere warm. Re-oil the bearings once it is dry. If it went through anything gritty, wash the grit off before it dries in place.

Worth knowing

Do not put a wet model straight into a sealed box or bag. Trapped moisture with no airflow is the worst case for corrosion.

What a free account actually does

RC Crash Crew remembers your RC so you don't have to. Every run, every battery cycle, every breakage and every fix — kept with the rig it happened to, for as long as you own it. No cost, no advert, no catch.

🏎️ Your garage — the part that works on day one

Build each rig properly: what motor, what ESC, what gearing, what tires. Then keep its whole history in one place.

  • Run log — where, how long, how it went
  • Battery health — cycles, puffing, when to retire it
  • Component hours — what is worn out before it fails
  • Setup sheets you can copy between rigs
  • Radios and model memory
  • Photos, kept with the rig

  • Crash Bay — log the damage, see what other people broke
  • Repair Desk — what you did, and whether it held
  • Tune — symptom in, fix out, by chassis type
  • RC AI that can see your own rigs and answer about them
