How many time can you use the rocket?

As many times as it holds up. 10-20 times if you do it right and take care of it.

The rocket is completely reusable - the only one I have ever lost came down in a 60' Oak tree and was lost that way. The ENGINES and wadding have to be replaced between each flight. You can buy packages of three engines with sufficient igniters and wadding for three flights separately. They can be ordered on Amazon - we usually get ours at Target or Wal-Mart simply for convenience. These are real solid fuel rocket engines - these rockets do not uses pumped pressurized water or air like some other systems for propulsion.

Virtually an unlimited number of times, provided that nothing goes wrong like a parachute melting causing it to crash.

That depends on how long you need to use it for each meal. If I use it three times a day for about 10-15 minutes each time, I can get about a week out of the fuel canister. I also use MSR fuel instead of Primus fuel.

As far as age group, I'd say old enough to where your kid can stop on a dime if told. I love rockets but they can be dangerous if not given the appropriate respect. With adult supervision I would not go under 6 (I insert engines, igniter, and place launch clips). These rockets are impressive to young kids. To do them alone, I would not go less than 11. An 11 year old could easily build it too. Be smart and safe. Have fun!!

That really depends on how much force is used during launch. My boys liked to jump on the launch pad and the rockets would go flying!! We "lost" several rockets on our roof (2.5 story home), so I do suggest that you move the launch pad away from anything that could potentially capture the rockets. But a one-footed good stomp could get these rockets flying a good 10-15 ft. in the air. It's a fun toy!

No! You can use them over & over & over, until they get stuck on the roof. :o)

I don't see why not. The rockets are seperate from the launcher. The rocket shafts are plastic so you could paint them a different color or put stickerson them or write something on them with a marker if you wanted. And yes, after that you just put the rocket on the launcher and stomp for lift off.

you can do them as many times as you want... you can do one and undo it, then do another one and undo it... you can even mix them in one circuit ... :D ... I bought ScienceWiz / Electricity Kit too.. and my sons (5 & 7 YO like to mix them all.... although these two kits have very similar stuff it's fun and my kids don't need to fight for material .... I warn you, these are very simple material that any one can get anywhere, but this kit is cute for a kid :)

It doesn't say this on the instruction sheet posted on the website. In fact Kiddie recommends running drills with it. It wouldn't make sense for it to be a "one time" use. You need to practice with it so everyone feels comfortable using it.

As many times as you want. The product will stop and then you just need to start a new session.

Wow..., what a question! Probably 10-20 years if you never use it. One hour at full blast.

Since my grandchildren only get to visit from out of state a couple times a year, our rockets have not gotten a work out to experience the same problem. Sorry I cannot be of assistance. Siince they don't cost that much and the joy the kids get, perhaps it would be best to just replace the rockets. Sorry.

I'm not sure the exact number of times but sufficient to keep chicks developing safely. You could time one slow rotation and use it to determine how many times an hour then a day.

If you are going to launch it on your own yes. I bought one Estes set that had a launch controller. This is because I have always launched with a rocket club. The club I belong too has a launch pad to accommodate 10 rockets at once with a switch to choose which rocket to launch. To find a club near you, you can go to http://www.nar.org/find-a-local-club/nar-club-locator/.

90 or more, my Grandson has been using this set for almost a year now, it has become everything from a interesting invention to a space station to launch his rocket..this set is well worth the money!!

Yes. 20 times on/off a day within 24 hour. It will repeats again on the next day.

I have only used mine 20 times or so since purchase, but i have not had any issues with it.

You can only pump once. That one pump is enough to carry it at rated speed. If you do it more than once nothing more happens.
