Can stick drift be fixed?

Sometimes, and it depends on the cause. Drift from a dirty or mis-tuned stick can often be resolved with recalibration or a deadzone adjustment — worth trying first, since it is free. Drift from a physically worn potentiometer usually needs a stick-module replacement, which ranges from easy to fiddly depending on the device. The durable fix is buying hall-effect sticks in the first place, since they have no wiper to wear out. When we weigh inputs, drift track record and repairability both carry real weight.
