"Good to Have on Hand"
FinBurner (Brandonbacn@outlook.com)
I purchased this because I use C6-5 engines more than any other. Almost any low-power rocket can use them. It's nice to always have some on hand for those last-minute launches (especially early in the morning before anything is open). The box it comes in is also handy for storage.

"great fun and cheap!"
I bought these engines for my homemade rockets also for the starter set Rascal and Hi Jinks. I would also recommend those items.

As expected. Gives you what you want. No frills but lots of thrills.

"Go to engine"
These are our go to engines for most of our 18mm rockets. The 5 second delay is the most versatile of the options, and will work well for all but the very heaviest 18 mm rockets. The delay is a little short for the minimum diameter rockets like the Estes Hi Flier, but that is a good thing as it keeps it within site...just barely.
