"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.

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

"Good for getting bigger birds launched."
Worked every time. Very reliable rocket engine. These engines performed just as expected. I'd order again without hesitation.

"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.
