OK Doug, you win. 😛

Update time.I finally got the glassing done. 6oz strips in the fillets, 6oz tip-to-tip, and 1.5oz sanding veil. This was my first tip-to-tip job, and twas not easy. Looks a little ugly, but should clean up nicely with sanding and…   Read more»

I finally got started with the retrofit of the 38’s. Making it so the 2-grains will fit.3 pics at:http://www.putfile.com/pic/8430955Ken

Joe, is it 2 or 3 that you have? Loaning would be great, as I don’t (or at least I didn’t think I would) have much use for a 38mm G in normal usage.I’ll get with you if I need…   Read more»

Ron’s Quark has been great on the I300T. That would be my recommendation for the drag motor.Or H999? I like ’em.Ken

If the unidentifiable LCO markings were from Saturday afternoon to evening, that would be either Adrian or myself. We both tended to have a typical engineer’s scrawl. No offense Adrian! 8)Ken (KF on LCO or RSO boxes)

I think it would be very helpful for the PM job (and the RSO if he’s doing pad assignment as I did), to have some sort of identifier at the pads to tell what rod/rail is on each.Something like a…   Read more»

I totally understand Bruce’s frustration, as I was supposed to be working pad manager from 12-2, but got bogged down in my 1 flight of the day. I ended up working from about 2:30 to 6 doing pad manager, RSO,…   Read more»

Give me DIP switches or jumper blocks any day!Ken

Ain’t hi-res digital photography great for failure analysis?!Looks like you need bigger shear pins into a longer coupler??? That or a one-piece sustainer with all-out-the-top dual deployment (tethered main).Cool flight nonetheless! 8)Ken

Did everyone on the email list get pinged on this emergency? Some might not be checking the website very often, especially during the last week prior to launch when we’re all trying to get things wrapped up and ready.BTW, I…   Read more»

Go to the NFPA site, search for 1127 or other code.Go to the specific page for that document, then at the bottom, there is a link to “View the 2008 edition of this document”.I tried pasting a link, but it…   Read more»

You can view NFPA documents for free on their site, just not download them.Ken

Mike,Removing those PCB mount SMA connectors can be a bear, especially with a ground plane on the board. I generally sacrifice the connector, cutting bits of it off at a time with some strong cutters, to reduce the thermal mass…   Read more»

I unfortunately cannot make it this Saturday. Family obligations come first, so I’m trading this weekend so I can have MHM open.Maybe the next one.Ken

It’s really a matter of what you’re looking for. I liken it (in my field) to a full functional parametric test vs. a pass/fail test. Do you want to get all the data while the rocket is in flight (i.e….   Read more»

Mike installed it in his 3″ bird with the only mod being an antenna cable. By pulling the guts out of the waterproof and rugged housing, I think he said it would fit 54 or maybe even 38mm? Mike?Sure wish…   Read more»

Warren,I’ve been in disk and tape drives for about 18 years now. Zero gee should have zero effect on any of these storage devices. As Mike stated, you do need air, though. The head media spacing is a balance between…   Read more»

I wonder if using shielded or twisted pair wiring would resolve some or all of the RF coupling issue? One problem I note with most altimeters is that except for the power supply negative terminal, there’s not much in the…   Read more»
