Edward Q. ★★★★★

The spacers made setting up my D13 motors for precise delay times much easier than I expected. Everything fit together perfectly, and having three kits in the pack means plenty of spares for experimenting.

Lily ★★★★★

The O-rings and insulators included in the kit fit snugly on my D13 motors, taking the guesswork out of adjusting delays mid-build.

Owen ★★★★★

Three packs of delays means I can keep flying D13-7W motors without hunting for spares. The O-rings and insulators were all in the bag, which saved me a headache on the launch pad.
