Sophia K. ★★★★★

First launch with the F39-6T went off without a hitch—the spacers lined up perfectly and gave me exactly the delay I needed. Three kits in the pack means I’ve got spares for testing different motor combos, which is a nice safety net for a hobbyist.

Matthew ★★★★★

I've been using these delay kits to fine-tune my D9-4W flights, and the included O-rings fit perfectly every time. The spacers make adjusting burn times straightforward without guesswork.

Violet ★★★★★

My first attempt at adjusting delays for my high-power rockets went smoothly thanks to these pre-sized spacers and O-rings. The three-pack covers a couple of flights, and the instructions were clear enough for a hobbyist like me.
