"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.

"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.

"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 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.
