Penelope ★★★★★

Ordered these for my E23-5T reloads and the delay elements dropped in clean, no trimming needed. The O-rings and insulators included in the kit saved me a separate trip to the hobby shop. Ejection timing came out dead on both flights.

David K. ★★★★★

Grabbed the 3-pack because I fly G76-4G reloads pretty often and it's nice having spares on hand. The delay insulators and O-rings are all included, so no scrambling at the launch pad. Delays burned right on time, I'll be buying these again.

Hazel ★★★★★

Picked these up for my E23-5T reloads and the spacers fit perfectly in the liner, no trimming needed. All three delays lit clean and the ejection timing was right on. Nice to have spares on hand instead of buying one at a time.
