Jim Have you given any thought that maybe instead of a complicated active stabilization system a simple spin stabilization could be used to achieve a more vertical flight. Huge multistage sounding rockets have been flown successfully for decades with only pasive stabilization (fins with a...

At our local rocketry club we have been flying full scale toilets for about 12 years now. Every year in October our club organizes a large model rocketry (FAI) competition where people come from all over Europe. Competition runs from friday to sunday. On the field we have large tents where...

AWESOME. https://www.youtube.com/watch?v=PnsFFhKqXXo

Measurement Computing USB-201 (https://www.mccdaq.com/usb-data-acquisition/USB-201.aspx) seems like a good option. 12 bit resolution and 100kS/s sample rate for $99.00 is pretty good.

Cool. Rocket lottery. I'm in.

Mach 2.4 with a homemade sugar motor: https://www.rocketryforum.com/showthread.php?66821-Sugar-rocket-flown-to-25-000-feet

I'm still looking for an ARTS 2 flight computer. If any of you has it and doesn't plan to use it, please send me a PM. I will pay for international shipping.

Here is an additional launch video made by my friend with a GoPro camera: https://www.youtube.com/watch?v=zImHsYWY9-s

That's right. It's just four aluminum fins TIG welded to a short piece of tubing with a thread on one end.

About a week ago I successfully launched a rocket with a homemade sugar motor to over 25.000 feet. The rocket itself is more or less a flying motor case. Basic construction is very simple. Aluminum fincan is screwed to one end of the motor and on the other end is attached a short piece of...

Recently I was in an aviation museum in Belgrade, Serbia where pieces of a F-117A stealth bomber can be seen. This airplane was shot down in 1999 during the war in Kosovo. What is the most interesting is how the decades old russian missile system was used to shoot down at the time one of the...

Here is a fiberglass sugar M motor I static tested last year.Worked great. https://www.youtube.com/watch?v=Q2YJtmsqKSU

Looks awesome Damian. I'm allready looking forward to see this bad boy fly at FM 2014. Andrej

Here is acceleration data. Please note that acceleration data is just raw data from the sensor. I haven't yet converted them to G's or m/s2. Arek just added a new page in Arecorder manual describing how to convert data.

I work as a technician for a public water supply company and machining is just one of the things I had to learn in order to be able to build rockets like this. Waiver restrictions are a bit different than what you are used to in the US. Since I'm the only one in my country launching amateur...

Thanks. I'm glad you like my projects.

Well, there really isn't any other choice. Here we don't have any open unpopulated places. This launch site is on the army artillery range which is mostly forest, except for some clearings here and there. But it's not all that bad. If the rocket lands on the tree that is usually good because the...

Last friday I launched a small scratchbuilt rocket powered by a 60mm K-1200 sugar rocket motor. This flight was made to test a new rocket flight computer. Entire rocket was built in three days from spare parts laying around in the workshop. Everything worked as planed. Data from Arecorder...

He should know that something bad is going to happen when black cat entered the scene.:facepalm: https://www.youtube.com/watch?v=SFnSclfTkq8

Phil what kind of electronics did you use for staging and for tracking? Was the 2nd stage motor ignited with a head-end igniter or did you run the wires through the nozzle? How was the recovery setup? Did you have some kind of dual deployment in the second stage or just a single small chute?
