Spotlight Review

"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.

"Great buy"
I buy the assortment pack (A B C pack) and this bulk pack. I could almost get buy just buying this bulk pack.1 We use more 2 or 3 times more C6-5s than any other 18mm engine available. Great that it comes in a bulk pack. A busy day for us is 10-15 launches in a morning. No brainier if you plan to go out to a field more than once in a year.

"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.

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