Mars project Phobos EAV (2006-01-22)MARS is a British high power - amateur rocketry group. This project uses a kosdon O-10,000 (can you tell I am a bit obsessed with this motor?) and a boosted dart rocket. The goal first of all was to ... [Read More]
Kosdon O-10,000 in a boosted dart (2010-06-27)Altitude was not as expected because of a separation problem. Still, for an O, it did get some pretty decent altitude. Most importantly, the O booster did recover. Here is a post about the motor. ... [Read More]
Freedom Phiter - 3x Kosdon motors (2010-10-11)Additional footage of freedom phiter. This is obviously lifted from a Pad 39 productions video so it may not stay up forever. Got to love the scream this rocket makes on the way up. [Read More]

Kosdon P 10,000 on Ebay (2012-08-10)I took a short break from rocketry and wound up missing tons of crazy stuff! Combine this kit with an all-motor N 5800, with a 20 second staging delay, and I think you could have a ... [Read More]
Kosdon rocket with 20 second burn time (2012-12-27)This makes the N1100 look fast! Put one of these as an upper stage to a faster N and 100,000 feet should be in the bag. [Read More]
Phreedom Phiter (2007-11-28)This great rocket, flown a few years ago, contains I think 3 Kosdon M-3000 motors, or something along those lines. Very nice sound, would have been better in person. No rocketry people are not ... [Read More]

OuR R motor project (2011-02-09)About 13 years ago, this was the rocketry article that got me back into the hobby, and into HPR for good. It was my rebar moment. I walked into Barnes and Noble and saw a huge rocket on the front of ... [Read More]
