Snapped right into the nosecone holes with just thumb pressure, no drilling or glue needed. Twelve in a pack is plenty since I only used four on my payload bay. They hold tight too, haven't popped loose after a few rough landings.

Finally got around to swapping out the old retainers on my payload bay and these pushed in with a satisfying click, no tools needed. The 12-count pack gives me plenty of spares for the next build too.

Fit perfectly into the LOC airframe slots on my Modular Motor Can, and the push-in design made swapping out the retainer clips a five-minute job. Twelve per pack is plenty for a couple of builds, and they hold snug without any wiggle once seated.
