I share My ‘Rocket Room’ With: Washer/Dryer. Three Cats. Furnace.Hot Water Heater. Computer.All my rockets have cat hair someplace in the paint, or glue. It mayjust make them stronger.Great MOON out tonight.

If that was your rocket shop, we need to talk.My wife will not enter my rocket area — too messy.Some things just work out ever so well ;-)Nice Rocket.Still love your Solar Flare!

It’s work……. would be nice…….. Can not do much there. Customersmay get the wrong idea.

Yes, please tell us that’s your place of employment and not your rocket workshop!!!We will all yell No Fair, otherwise!-Ken

That is the cleanest and most organized hobby room I have ever seen!

mmmmmm yes.Why stop at 5.5 (it probably is the perfect size)I did an 8″ and will again.http://ral-photos.smugmug.com/Rocket-Launches/2009-Launches/NCR-Oktoberfest-10-3-09/16950754_TfZWGq#1281752352_NLJLP4m-A-LBif I had used just one motor, not four. It would not have lost the fins. 8OWhy not go over the top and…   Read more»

Does this mean that I have to start my 5.5inch Swift 220?Ron

BEAR, the concrete pad at the Atlas site was part of the LOX cooling system and is called a spray pad. They had a recirculating evaporative chilled water system the sprayed water over the pad which then recirculated back through…   Read more»

There is a LOT of snow out east and it would NOT have been fun. Flyers would have had to shovel snow off the pad to set up. Skipping today was a great call! (Though I’d have enjoyed coming out…)

Funny, I thought NCR’s Creed of the Rocketeer was: “neither snow, nor rain, nor heat, nor gloom of night, nor the winds of change will keep us from launching our appointed rounds.” Especially after this most recent Oktoberfest experience. I…   Read more»

Not happening. NCR’s scheduled November launch has been cancelled. Apologies for the late notice. Weather concerns (Cold, Cloud cover and Wind) and launch site conditions (snow and mud) have made this the most sensible decision.NO LAUNCH. Regrettably, we won’t be…   Read more»

Any updates on the launch status?

Agreeing and adding to Warren’s comments. Most of the altitude junkie birds have relatively small fin areas, so the booster section with motor casing will become unstable once detached from the upper section. This makes going “drogueless” perfectly acceptable.In a…   Read more»

Rich, I’ve built birds that weigh over 20# and have NO drogue. They just break apart at the ebay joint and deploy a long shock cord and fall from apogee without any drogue whatsoever. You’ll find guys like John Wilke…   Read more»

Thanks everyone for the advice! I understand now why it’s best to put the main up top and the drogue down below. And, I will definitely ground test my charges.About using rivets/screws on the ebay instead of gluing it to…   Read more»

Shredder, just about every dual deploy L2 and L3 bird I’ve ever seen deploys apogee out of the middle of the airframe and main out the nose. There are a variety of reasons for this:1- When you break in the…   Read more»

Id agree with not gluing in your ebay, its just not necessary and rivets are quick and easy. For your apogee deployment I would deploy out your nose cones. Reason being if you deploy out the bottom your trying to…   Read more»

also I need the weight of the main up high. it helps with the CG and CP

The main reason for the main in the top and the drogue in the lower airframe (booster) is the mass of the objects at the ends of the harness:With it set up how you’re planning, when the drogue pops, the…   Read more»

Hey Rich, this sounds like a good plan to me. I know I am nowhere nearly as experienced as our esteemed experts, but it is similar to what I have been told. I am an L2 and I have asked…   Read more»
