🧰 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.
