Andrew J. ★★★★★

The O-rings and insulators included made setting up my F12-5J motors much easier than I expected. All three kits worked perfectly during my first launch session with no issues at all.

Elizabeth ★★★★★

The three delay elements and spacers fit the F12-5J casing perfectly, and the O-rings are exactly the right size. I’m glad I grabbed the pack so I don’t have to reorder after every launch.

Claire I. ★★★★★

Exactly what I needed for my F12-5J motors. The included O-rings and insulators saved me a trip to the hobby shop, and all three delays worked perfectly
