Daniel ★★★★★

Swapping the delay elements in my E18-7W motors takes maybe two minutes with these, and the included spacers fit snugly without any rattle. Getting a 3-pack means I'm set for a whole weekend of launches.

Hannah B. ★★★★★

The delay elements fit my E18-7W motors perfectly and the included spacers made adjustments easy. Got three clean deployments in a row at the field this weekend, no misfires.

Adam Y. ★★★★★

I picked these up for my F24-7W reloads and the timing was dead on, right around the 7 second mark. The spacers fit snug in the forward closure and I didn't have to sand anything down. Three in a pack is nice since I usually burn through a couple per launch day.
