I used to launch these back in the 80s, then got my kids into them a couple years before the Pandemic. Then really got into it the first two years of the pandemic.

Couple pointers:
1) If really dry, there is a fire hazard as the engine remains hot for some time after ignition. The engine should remain in the rocket, but the ejection charge sometimes blows it out. That is the greatest fire danger right there. You won't catch normal greenery or houses on fire, but if really dry and launching over dry grass you can get flames.

2) No one has ever called the cops on my kids - and we live in the metro Boston region. Find a large suburban field (think a complex of soccer fields) and if anything you'll get curious onlookers. There are model rocket parks but they have all sorts of membership requirements and scheduling, just easier to go to a complex of soccer fields. These aren't loud so unless someone is looking in the direction of launch they're going to be completely unaware you're launching if driving by or even walking a quarter mile away.

3) You will lose rockets. Depending on the size of the field, I found I needed 4 - 6 rockets to justify a trip with about 25 launches. Don't let your kids talk you into a nice paint job. Couple rattle cans of paint and the decals is more than an investment of time. Bring a 5 gallon homer bucket to sit on and another to put trash in.

4) If you get into the hobby go get a small car battery for launching - you can get further away from the launch pad and it is more reliable than 4 AA batteries. The plastic plugs for holding in the igniters is pretty good, but masking tape is the old standby and works better.

5) Big engines are cool but honestly, my kids preferred mid-sized engine launches - less likely to lose a rocket, slower flight so easier to follow rocket, and since they're cheaper dad buys more.

6) If any little kids come by to watch and their parents are there - invite them to press the button to launch one. A little goodwill goes a long way if anyone does complain.

Requires an Estes Engine
Both rockets require a specialized Estes engine to launch. For the Amazon, Estes recommends a B4-2 engine for your first flight. The rocket is also compatible with other Estes engines, including the B4-4, B6-2, B6-4, C6-3, and C6-5. For the Crossfire, Estes recommends the A8-3 for first flight, and the B4-4, B6-4, C6-5, and C6-7 for more advanced launching.

I used to love building and blasting off these. As stated above, if you have a local Hobby Lobby they frequently put rockets on clearance. They also carry a basic selection of engines in store.

My kids' last build we started off small and went to the biggest listed on the box. Never to be seen again! When I was a kid we ran out of C's so rubbed a D on the sidewalk until it was small enough to fit. That one suffered a flight anomaly - we found it, but it never flew again.

Right? I don't know if the likes of Hobby Lobby have a decent selection of plastic model kits in store, they seem expensive esp with paints and glue and required. I had a huge selection of Testors paints, rattle cans, enough plastic cement to get a small city dizzy.

I've had trouble with igniters/starters lately. They either flare but don't start the engine or don't go off at all. I've rigged overvolted lines, etc. Maybe a set of bad batch product. That said, DIY make your own instead of $1 each: https://www.youtube.com/watch?v=3L6FX7AQPIA

I loved this stuff, but every rocket I ever launched I ended up never seeing again, so it ended my hobby quickly when I was younger, lol.

You need a lot of open space and a clear non windy day for any chance to find the rocket after launch unless you use the weak engines....
