Last can I bought was from Tim at Giant Leap right on the launch field. Doug

Good for you Conway. I won't use them. I can't see any advantage to the eyenut method, other than a slight weight savings, but you have to admit there is the possibility of them backing out in fligh...

I'll send you a PM. Doug

Bruce, your question is why I don't use eyebolts or eyenuts. It is possible for them to un-thread especially if one section of the rocket like the fin can is rolling. I bolt the motor in with a bolt...

Bosun Supply is great and the prices beat the hell out of McMaster-Carr. I'm not sure how you figure that Warren. Price on these items is Bosun 3/8"$20.13 rated at 1160 poundMcMaster 3/8"$21.70 rated...

Sorry JW, it's still too early to tell. Art and I are building a new rocket that we hope to fly at MHM but considering it's still under construction... I hope to post some more information around Ap...

The way on the bottom is actually the correct method. The other method results in an unstable piston. Sorry to disagree with you Edward but I've seen that site before and his theory, analysis and "te...

Yea, they won't let any rocket fly with any "exposed" aluminum. It can have aluminum fin cans, nose tips, etc, but it must be painted. Of course no aluminum airframes but painting an aluminum piece ...

I guess so since they won't let it fly at Argonia for LDRS 27. It has to survive its maiden flight at MHM first. Doug

Absolutely, the flight I described before was traveling horizontal by the time the last stage went off. It was so small though, no harm, no foul, just cute. Doug

It IS an altitude contest - without question. The rest of the rules just make things harder and more constrained. Yes, but Warren it sounds like from the first post that these constraints are becoming...

Finally, as Doug will attest - when it is no longer a "single" shot event, then anyone traveling any distance is placed at a huge disadvantage. Were it a single flight, some of us would show up and go...

Has any one done 5 stages? Yes. I saw a tiny model rocket that flew four stages of A10's each and then an A3 I think. All I remember was, Pop, Pop, Pop, Pop, and Whoosh. Kind of cute actually. Doug

Kids too small to move quickly or understand the danger, adults in wheelchairs or on crutches, the blind or otherwise disabled, all have no place at a rocket launch where significant dangers exist. I'...

I use Fiskar's scissors. I like to seal the edge with CA first but I've had no problem cutting it. Doug
