Rocket with gps/waypoints and mutch more..

Hey guys,
im thinking of using a multicopter control board (in name Mikrokopter) with special firmware to stabilize (mems gyros) and control a rocket.
it will be able to fly to gps set 3d waypoints, and return to home.
elektroniks and software is no problem.
BUT
i have never build a rocket (weight of the elektroniks will be 180g without servos for the control surfaces). i think hard motors are not the right thing for me i need more range. are there rc fluid rockets ? if anyone can help me that would be great.

sorry for my bad englisch

Don't know what country you're in, but in the US & Canada any sort of guidance like you're describing is very illegal. FYI

Try one thing at time. There are plenty of larger solid rocket motors to try. What experience do you have?

Sorry to resurrect old thread:

CF105: Where does it say that guidance is illegal? I can find organizations rules that don't allow for rockets with guidance but I can't find an FAA document that says so (didn't check Canada). Could you provide a link?

Thanks!

If you build it, they will come.

You're kidding right? You don't need a link! Common sense is the only link you need....

An individual builds a rocket with guidance to go from launch point A to target B.....come on.....really? Ask yourself, why would any private citizen want to build a guided rocket. Homeland security will be asking the same question.

There is a reason why the rocketry organizations don't allow it. If an individual could build a guided rocket without restrictions, so could someone with "not so pure" intentions.

Active stabilization is a different story....

Fortunately in a free country, you do need it in writing. If there isn't a specific law banning an action it isn't illegal. I've tried to find a law myself, because so many people ask but can't locate one. I'm not condoning the building of a missile by anyone. It's definately bad for our entire hobby. I beleive if you have a few people building guided missles the opponents of fun will quickly make all model rocketry illegal.

You can not however, assume something is illegal because it's a bad idea. If someone knows the law, I hope to see it posted.

Thanks.

About the closest I can find is:

NFA TITLE 27 CFR CHAPTER II
PART 479—MACHINE GUNS, DESTRUCTIVE DEVICES, AND CERTAIN
OTHER FIREARMS

479.11 any rocket having a propellent charge greater than 4oz that can be used or assembled into a weapon is defined as a destructive device and falls under the National Firearms Act.

-- If it is designed to home in on a target or waypoint it will be easy to argue it could be used as or assembled into a weapon.

Not familiar with the details of US law (being a Canuck & all...), but have heard/read about it plenty of times from NAR and TRA members. Besides... if word got out you were working on something like this (this is a public, online forum...)... how many gov't agencies would you attract (FAA, BATFE, FBI, HSA, who knows what else?)? No one needs that kind of grief, and our hobby *really* doesn't need that kind of publicity.

On the Canadian side, this from the "Requirements for Launching High-Power rockets in Canada", from Transport Canada:

Quote:
9.11. No person shall launch a high power
rocket horizontally, or at an angle
that takes the rocket beyond the
boundary of the launch site in the
event of a recovery system failure
resulting in “ballistic recovery”.
9.12. No person shall launch a high power
rocket as a weapon at a surface or air
target.
9.13. No person shall launch a high power
rocket that creates a hazard to
aircraft.

Also this:

11.1. Launches shall be conducted in an
area and manner that will not create a
hazard to persons or property.
Now, if you're talking about some sort of GPS guidance for the parachute recovery phase, that's one thing. But if you're talking about guiding the rocket during boost or coast, forget it. The exception is if the guidance is to help keep the rocket vertical; in Canada at least, that *is* allowed.
