For those who tweak and trim their models, these 3mm x 0.5t light blue collars come ten to a pack and make small spacing changes straightforward. The coloured finish aids quick identification when swapping sizes during setups.
Install them where accurate clearance is needed, such as on drive shafts, shock mounts, or link rods. Their slim profile is handy for tweaks that require micro adjustments without affecting geometry heavily.
These collars work with a broad range of RC vehicles that use 3mm shafts. They are useful in both new assembly projects and when improving fit on existing parts.
