Epoxy the bulkhead in where the top of the longest casing will be. Then, just use an eyebolt, or eyenut with allthread to go through the bulkhead into the threaded closure.Ooops. Forgot the Pro54 doesn’t have a threaded front. I…   Read more»

If you don’t want to use a delay or smoke grain put the nut on the inside for more strength.If you’re talking Aerotech hardware, you’re guaranteeing a front closure blowout by leaving out the delay. The motor structure relies on…   Read more»

Mike,If you’re going with the CTI J285’s, definitely airstart them! The Perfectflite timer is SO simple to set up, and fully ground test. And with CTI motors, it JUST WORKS. No dark art of igniter augmenting required.If I can just…   Read more»

Yup, your stars and bars are upside down.I’m sure you can fix it with some of that amazing hand-painting talent!Looks awesome. I love the metal fins with rivets look.Ken

I installed my sustainer and 3 airstarts igniters at the pad. It took quite a while and possibly backed up the line, but I thought that was the rule (real or not) for motors G and up. I could see…   Read more»

Yup, forgot about the home-brewed motors. Should be quite a help to those pursuing the dark art.It’s on my list, but way out there right now. 1st employment, 2nd L2, then …Ken

For those of us who fly almost exclusively with the club, I don’t see how this ruling affects us that much, as Tim is at nearly every launch. Those rare occasions, it would be nice to have a small stock…   Read more»

Not sure how they’d compare in tensile strength, but aluminum threads can strip really easily. I didn’t even notice the weight of the rods in my LOC ebay. It kind of got lost in the mass of a 4″ rocket….   Read more»

Nice pics, Mike S.Mike K. … The flight looked errr sub-optimal. 😯 When it’s rebuilt, I suggest the following if going Aerotech motors again in a cluster:1) Use Blue Thunder propellant – much easier to light2) Lightly sand the ID…   Read more»

I’ve gone through Wildman for all my PR stuff. Excellent customer service there. No direct experience with Curtis.Ken

I called and apologized to Mike, but I won’t be there tomorrow. I have a job interview Monday, and I’m going to prepare for it over the weekend. Wish me luck!Go get ’em Bruce! Find anything you can on the…   Read more»

Anyone in the Longmont area have an Astro gps I can borrow to test some DC20’s I bought on ebay? I just want to make sure they’re functional before leaving feedback.I’ve got a week and a half of real vacation…   Read more»

If there’s time, post some pictures of the DC-30 in “as delivered” and “for rocketry” configurations. Throw a ruler in the picture for some scale, or next to a DC-20 for reference.For my planned re-housing of the DC-20 (or 30),…   Read more»

I don’t think even Mike has dissected a DC30 yet. Would be nice if they’ve shrunk it further or fixed the problem with the antenna connector going the wrong direction (for us anyway).Ken

That’s great news, as I’m overbuilding a LOC Legacy for the I200 right now, and I’d rather not lose it.Ken

I thought (from Mike Konshak’s work) that 38mm was just slightly too small. I remember he tried to grind off the corners of the pcb, but either shorted layers or cut traces when he did so.I’d like to draw up…   Read more»

Scott,You might try what I did for the GPS in my 4″ cone. Once you have the weight where you want it, wrap up the gps in anti-static foam or bubblewrap, just to give it a smooth shape, then 2-part…   Read more»

If the laundry fit is very loose, you can get away with the charge above the laundry for the aft-most deployment. I’ve had 100% success so far this way, but it’s been a 16″ drogue in a 4″ tube (VERY…   Read more»

Yup, it seems like a steal to me, too. Unfortunately, unemployment takes away all good deals! Yeah, I’d buy that if I were you.Ken

Chad,At 6.5lbs, you could still lob that up with a decent I motor for 50 bucks or so. Heck, even the H999 will kick it up. The Wildman DD is almost the same as my PR Comp3, which I bought…   Read more»
