How hard is to get Thermite? Sounds like good stuff. Thermalite sounds about like what you'd need for that 2-stager "hard to light" project! 😀 Ken

Tim, Sounds like Plan A might just be back on line. In my case, I don't want the central to light the outboards, but I think we could shield the dipped ematch/Thermalite combo with basic masking tape...

After 4 decent flights on just the central 38mm motor, Excess In Moderation is being called up to fly like it was made to. It is a 4.5lb LOC Fantom EXL with 6 additional 24mm mounts. Note I said 24....

Very nice work. Now Warren, if you're going to that much trouble for the thrust ring, why not just machine in the male threads half of the retainer as well? Save you all the extra bolts... 😉 Maybe m...

That does seem to be a helluvadeal, but I noticed that it does NOT include the Hypertek tanks. Any idea what THEY run, and I assume that the volume of the tank dictates what impulse range you're in. ...

Art, Since the magazine is no longer in print, can you scan and post the MHM article/photos? Ken

Very nice shop setup. I'll have to see if I can use the bandsaw here at work when I start on my PR Competitor3 (my Christmas present to myself... do you see a trend here?) For PR components, I highly...

The fireball has worked well for me (3 out of 4 times, anyway 😕 ) The 4th flight had an early eject and the chute pulled the harness quickly down the side of the airframe before the ball even hit the...

I think there are a few different "rocket curses" out there. I nailed my L1 on the first try, flew it on a couple more I's with perfect deployment at the top, then had Art put a beautiful paint job on...

I'd certainly be interested. I have a much greater fear of losing a rocket than destroying one. A long-range "here I am" call without HAM licensing would be sweet. I've been avoiding the temptation ...

As a recent victim of said zipper, let me say I've done a bit of reading and there is no 'perfect' solution... It's just you against physics. I had a reasonably long harness (~20'), but with an earl...

I have yet to do my first DD, but from everything I've read, drogue in the lower, main by the nose is the standard method. The shock (even if mild) of the drogue opening would probably shear the pins...

Well, so much for the ONE person who knows anything about rocketry at Hobbytown, and knows what to stock in the stores. Might as well rename it RC-town, now...😡Ken

As long as you've still got sufficient room for the recovery system, the longer motors should be no problem. There's plenty of support in 14" of motor mount tubing. Heck, longer motors help move the...

Ron,If you're using ematches (or especially Cessaronis), one timer will easily light them. The PF timer can handle more amps than you can supply with a hefty battery pack. I plan on lighting 6 24mm ...
