I found i have an increasing interest in rocketry. And since i just bought some KNO3 i thought I'd make some Rcandy rockets. Although i had no success with the big rockets, the smaller Al/foil rockets i have excelled in.

my bad if theres already been a thread.

Unfortunatley, this is not worthy of a thread. Especially in a real part of the forum. It is a great website, with excellent information, but is actually well known.

Do not reply to this message unless you have some great information to contribute, not just a lousy apology. Take a look at all of the posts on this forum, and it will be easy to see that this is not the kind of forum I am sure you are accustomed to. I's are I not i, and a reputation is earned by your own work and research, not a search on google (which is expected not commended).

A really good site:cool: for flying a rocket before you build it is at :
http://exploration.grc.nasa.gov/education/rocket/bgmr.htmlNASA has spent a small fortune of OUR money on this, might just as well use hell out of it.

The simulators are the most fun. You design the rocket from the ground up, with a lot of user-chosen parameters for everything from type of fuel to the nose cone design, and everything in between (number and design of fins, degree of launch angle, height, length, nose cone design, CG vs CP, etc.).

After the design has been put in, the animated "launch" takes place on your command, complete with noise (lame), time to distance figures, altitude, distance down range- or CATO:eek:, as the case may be, and other info.

Check out the detail that occurs at the apogee of a successful launch- they thought of everything.:rolleyes:

Anybody wanting to get into KN/SU fueled rockets needs to take a look at Richard Nakka's well-publicized site:

The guy's good and between his and Yawn's site, a person could get a pretty good start.;)

I just thought that with the recent discussions of KNO3 and impact sensitive torpedoes that this would be a valuable resource.
