When dialling in an RC build, small adjustments make a big difference. The XRAY 366161 O-Ring Set offers a simple way to reduce unwanted movement by fitting over 6mm shafts and adding controlled clearance. The set contains 2.0mm, 4.0mm and 6.0mm thickness options.
These rings work across many areas of a model, from stabilising linkages to tightening splined parts. They are handy for tuning handling where a small amount of play is causing inconsistent response.
To install, make sure shafts and bore faces are clean, then slide the o-ring into position and verify there is no binding. Trim or replace if the ring interferes with intended movement.
