LOL No. I know the answer to that one. We fly on a farm and the farmer has laughed many times and said , "I have 1000 gallons of diesel fuel and 10,000 lbs of fertilizer - why are they bothering with you. If anyone could blow something up it's me..." No he doesn't require a magazine...

Craigslist and Yard Sales... I paid 20.00 for my tabletop drill press and it works great. I paid 25.00 for my scroll saw (16" craftsman adjustable speed). I paid 25.00 for my shop vac. (Big Ryobi - dry only)

I really think that is one of the best I have seen. EDIT: What I like is that it is passive relying only on "gravity" and it is an original approach. My own was satisfying until I saw this.

"Fish paper couplers" Huh?

Maybe a set of C11's staged to a D or E?

Terry - you're reading my mind - or my old posts! I agree with this completely. The bad part is that adding any additional requirements is always viewed with suspicion. Frankly most of today's L2 written test is stuff that fliers need to know before they launch their first rocket. I'm not...

The only social networking sites I use are "Our Planet" and "LinkedIn". I don't use either one that much. LinkedIn is useful for making connections for work occasionally and Our Planet is just a nice way to share rocket tales and have club members chat about club business - we have a normal...

My understanding is that you could also cast on the farmland (not your land) and that's OK. Transportation? Not sure - maybe you need to talk to an agent. I would think that what you propose is not transportation.

Make the bands brown - Practice Round with Low Explosives. BP is a low explosive...

This is an amazing looking rocket. Do you have flight estimates of the D and E powered version and the 2 stage version?

;) Of course not. But they might listen further after that and allow you to take it apart and show that it is NOT a missile. With your NAR/TRA membership card and your other rockets you can probably convince them without this. I was actually thinking about what happens if it lands far...

Those who said that a Tripoli member flying at a NAR launch are covered by Tripoli insurance... might do well to contact Tripoli and confirm this with the organization's insurance agent. My initial contacts with both NAR and TRA insurance folks has left me with more questions than answers...

Details?

What about honeycomb material or foamboard covered in glass? Why not butt the fin against the ring - then add 1/4 inch strips on each side of the fin to make a slot. Then you get the benefits of the thinner rings and the slots. Bond those slot guides on with wood glue and clamps...

This one climbs like a lame horse. Stompity Stomp... https://FantasticContraption.com/?designId=3494592 As though that wasn't funny enough - it then falls back down the tube.

By hook or by crook... here's a stubborn machine. https://FantasticContraption.com/?designId=3493950

This one made me giggle... I had to be different! I designed an anchor that falls and digs in just in time. https://FantasticContraption.com/?designId=3492188 Uh... by design I mean... well... It works!

What size tube is a BT30A? BT101? I'm thinking of downsizing this to 13mm BT5 for the rocket. Just trying to get scale info so I can try to figure out what's close.

Depth of tab is 0.2125 just over 1/5 of an inch. Good call for not having it in front of you. Just remember that 29mm inside of 38mm is roughly 5mm radius smaller and an inch is just over 25mm. Nope you are right on the money. The rocket is over stable even with the change. I took a LOC...

That is a sweet rocket. If you had it to do over again is there anything you can think of to lower the aft weight? One of the Hellfire's from way back used cardstock/posterboard shrouds to lighten the load. Could you make the front fins detachable for flight and only have them for show...
