What is the longest motor in 54 that can take? Edward

Fidy cents! Edward

Just read this and thought of an idea that might work to get the liner started to budge for the next time around. Take the forward closure (I'm assuming that it is tapped) and flip it around with the...

I would say you have to fly all 10 motors. If you did your A-F/G motors motor eject with altimeter for recording only. Your H, I, J would be DD. You'd have to be ready to fly when you got to the fi...

Here is something I was thinking about today at work.Fly motors A-J (your choice of motors) in a single day. You get 2 rockets with a total weight of 5 lbs. Highest cumulative altitude wins. Must b...

The other cool thing is at research launches even if you don't roll your own - if you have a rocket someone probably has a reload for you. And I second that I've seen less issues at research launches...

Ah, so that's a better difference. Though for the cost probably not worth it. Edward

No, I haven't. The cylinder that I have right now weighs 3.4 kgs and is aluminum. The equivalent from Luxfer on that page weighs 3.3 kgs empty. Not worth it for 100 grams. Edward

The M500 has a total impulse of 9000 N. I'm hoping to up that to around 10,000 N. I don't know about certifying it right now. I've been on/off about doing it. I don't think most people could build...

I'll have to get all the final numbers done for the M. It's kinda heavy and odd diameter 4.5" OD. The first priority of the M motor is a flight in HS-2 - a rocket built by John Bixler. To call it a...

Initial thrust is 200 pounds for about 2/3 of a second. Edward

I'm currently putting the finishing touches on the M 500 hybrid. Right now it's 98mm and burns for 12-15 seconds. And it's shiny. Did I mention it's shiny? I've got to sway you over to the dark si...

If you can wait until the new year Alpha Hybrids will have a 54mm I and J to offer. They are pre-filled tanks so there is no GSE at the pad. You need a scale and nitrous tank to fill them. In my te...

I use www.noaa.gov - same site but enter Carr also. It should all be within a Gelfand. Edward

I don't mind hauling them down but some weeks I'll have 5-6 ideas I want to test out and driving up here would be much easier than driving to Hartsel, plus I don't want to scare the buffalo. Edward
