Spotlight Review

This is a great choice for most 3 ounce or lighter model rockets. Best first flight engine for any lightweight fleet.

"Perfect, as advertised. Great performance"
Spectacular launch, great reliability. Shot all 25 in one sitting. Scouts were so happy with the height and the show. Each engine performed well.

"Not the best, but..."
These aren't the best engines but I don't think that's the point. These engines are for those times when you just want to fire rockets. It's not for performance, it's just for firing rockets. These engines are still good, which is nice, but it's the price of $2 per engine that matters.

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