Lucy C. ★★★★★

The three delay elements and spacers give me plenty of room to dial in the timing for my F52 flights, and the O-rings seated easily without any fuss. Took a bit of fiddling to get the spacer stack right, but once it's set, it holds steady.

Grace ★★★★★

These spacers fit perfectly with my G53 motor, and the o-rings sealed tight for consistent delays. Having three in the pack is handy for multiple launches.

John N. ★★★★★

Needed replacements for my F40-4W launches and the three delays plus spacers in this kit covered me for a whole afternoon of flights. The O-rings seated cleanly and the fit was snug without needing any extra sanding, so I'm stocked for the next few club meets.
