A very useful assortment for those that have several 18mm rockets. The A and B motors are ideal for 1-2 ounce rockets such as the Alpha and many others in the My kid's first rocket class. It makes sense that they do not include C6-7s in this kit, because any rocket light enough to fly well on that motor would most likely get lost with a kid flying it. The C6-3s and C6-5s are great for slightly larger/heavier/draggier rockets such as some of the fatter designs or 3-4 ounces (My kid's second rocket). One of the many advantages of flying with a club is that I can always swap with someone else if I wind up with too many of one motor or not enough of another. Plus it also includes wadding, so it's one stop shopping for everything needed for one or several enjoyable flying days.

This pack is definitely a good value. However, if you look carefully at the engines included, they are mostly short delay, low impulse engines. No C6-7, for example, which is an engine we use a lot. We have found that we have used all the larger impulse and longer delay engines from this pack, and are left with engines that we don't have as much use for in our selection of rockets. But if you are just starting out, we would recommend getting a heavier, low flying rocket, for the low delay engines, so you can get a sense of the size of your launch area. And get a smaller rocket that can use both the lower and higher impulse engines, and the longer delay engines, such as the standard Alpha III. If you use/need the engines included in this pack, it is a great value.
