Can't wait to try these :D

The other day a friend of mine was cleaning up his workshop, and he gave me these:

Kosdon I130

These loads are for the Kosdon 38/640 case, and use a 390 nozzle. They have a total impulse of 550 n/s, and have a c-slot configuration, which gives the motor a 4 second burn.

They are also certified... I have till Dec 2005 to use up all four loads

Doug you are beginning to suck even more than before....

only if he doesnt give one to me

Those are some of my favorite 38mm motors... they go great in a LOC Vulcanite (~7400 feet) or a LOC Expediter (~3500 feet). Nice long burn with a great flame, and LOUD!

Two of the Grains are marked Dirty Harry... my question is... was the I130 a dirty carry motor, or the Slow formula? Or did they call their Slow formula dirty harry because it produced more smoke? I am not that familar with Kosdon loads... I know two of the grains are certified.... but the ones mark Dirty Harry, I have to question?

The I130 was/is a C-Slot Slow propellant load... those are the ones that are certified, probably. Slow is basically a slow version of Fast. I bet Kosdon just used a little red iron oxide in the Fast to speed it up, the flames and sounds are almost identical (slow has a large orange flame, fast has a large orange flame separated from the motor by a bit). Compare the flames on my Arcas: K350 slow vs. K700 Fast . The Dirty Harry loads will produce a lower average thrust with some dense black smoke, and perhaps a longer burn time. (here's my I-ROC on an I255DH) I'd expect about an I110 out of the Dirty Harrys. It's only a little slower than slow... and none of Kosdon's motors are slow!

Sounds like fun

Sounds like a lot of fun. LOC Legacy's are made for a reason...

David's right. Even the Dirty Harry motors are incredibly fast. I saw one fly last month. It was an I 300 something or other. It took off quite fast and went pretty high.

The coolest Kosdon Motor i've seen so far is the Kosdon by Aerotech K600. Rob Bazinet flew on in a 3" all fiberglass rocket at METRA a couple of weeks ago. Nice and loud. Very cool.

Here's a pic of the Dirty Harry.

I have seen some awsome pictures of M dirty harry motors. Does anyone have any?

I really want to see those DH's Doug. When are you going to launch them?

 

[Rocketman248]

There's a really cool picture of a 7.5" Nike Smoke flying on an M1015 Dirty Harry in the Smokin Rockets photo gallery. It's about 3/4 of the way down. It's the 13th photo from the bottom.

I ran into a snag. Paul at AMW is away and won't be back in time for the next CMASS launch... so I am unable to obtain a 390 nozzle through him in time. So I was wondering if anyone here has a Kosdon 390 nozzle I could use with my I130 loads?

I need it by the 22nd

I will also e-mail the club list.

Nick, That was the pic I was talking about everyone should looks at it, it is so awsome
