If I can make it up for the meeting, I can bring up a “still in the shrinkwrap” bundle of 8′ lengths of 1010 and 1020 rail.1010 – 1″x1″ standard 8′ long $20ea.1020 – 1″x2″ standard 8′ long $40ea.I need…   Read more»

Unfortunately, there aren’t any record-setting motors in 2.5″ diameter. How about TRA EX records? You’re L2 now, time to start rollin’ your own! Maybe a 2.5″ 100% K or L in a low thrust, very long burn?Finish taking care of…   Read more»

That 2.5″ glass tubing and cone sound like the perfect setup for Adrian’s next step up the altitude junkie ladder!Did I hear right? John W. is moving back to CO? I hope it’s for good reasons rather than the current…   Read more»

Welcome to NCR! The Bob Smith epoxy should be fine for all but the more extreme builds. You can get West Systems (though at an inflated price) at McGuckins in Boulder. I just get mine online from Commonwealth or some…   Read more»

Check McMaster-Carr. Planning an upscale payloader?Ken

“reliable, repeatable method of lighting two motors simultaneously”Cesaroni Seriously, Mike. Make a cheap 38mm version in LOC paper tubing and use the 1 or 2-grain Cesaroni G or H motors to prove it out. I think you’ll be pleased. I…   Read more»

Maybe Mike’s a beta tester for Rocksim 9. It would allow all those additional pods with nosecones and motors.Ken

Mike,I’m sure you have a novel answer for this, and I hope to hear it soon, but how are you going to light the sustainer? With the motor being the coupler to the cradle, there’s no room to run leads…   Read more»

The Perfectflite mini and micro timers should fit your application. The mini will light anything if you’ve got enough battery. The weight penalty of the batteries would be the problem if you’re going for an altitude record or something.Ken

Amen, Joe!

I believe that is refered to as a “window” by those in the trade.Ouch!

But wait, there’s more. Thursday night,my wife was rear-ended, and our minivan will likely be totalled. Can anyone guess how much they’ll give me for a 10-year old van? :xMy wife is whiplashed, but ok. Luckily, no kids with her…   Read more»

If you get up into the AP motors, Blue Thunder propellant lights the easiest, and clusters very well. Other than my 6x 24mm airstart attempt where the timer didn’t arm right, I’m 100% for clusters 7 airstart ignitions. (Now jinxed)…   Read more»

I wonder if anyone has messed around with a helical offset core? That would give it the same burn geometry (at least in 2D), but eliminate the weight imbalance. As long as it were a perfect helix, the core could…   Read more»

I need a motor tho. Going to fly my finally built Firestorm 54 from Tim. Want to fly it on an H and maybe then an I if I get it back. I’m talking a 38mm Aerotech reload – sorrt,…   Read more»

Too much going on this weekend, so we won’t be up this time. Scott was bummed, as he was hoping to burn a bunch of motors and gain in his standings for most flights of the year (#7 right now).Warren…   Read more»

You might give Mr. Rouse a call. I thought I read something on TRF about him doing an aft closure with the OD matching the tubing, specifically for staged projects, but it didn’t go to market. I’ll try to find…   Read more»

I have a good friend who just started there a couple months ago. Not many openings there for what I do, but I’d be happy to put resumes in through him. He sits near the HR person. I hear they…   Read more»

If it’s for a Vestas wind turbine, they make those up in Windsor. They are why the price of balsa is going up! They are opening up a new plant for the nacelle (hub/generator stuff) in Brighton soon. My friend…   Read more»
