Just as an FYI, NCR does not have the capability of tracking records for anything other than single motor, single stage, non-clustered rockets at this time. While we would like to do so, we do not currently have the programming…   Read more»

The original charger should be inside the orange range box, at least it’s the last place I saw it. It is also possible that Dale has it.Warren

Speaking of which, Ed, I need my battery charger back. Can you make sure it is either in the trailer or bring it to the launch?Warren

Glue over an airframe or fins does nothing but add weight and perhaps a small modicum of water resistance. It does NOTHING for strength. To add strength, you need to add something for the glue to bond to that will…   Read more»

John Hall. He used to be a founding member of NCR from when Tripoli Rocky Mountain merged with PHITS (Punching Holes in the Sky) to form NCR. He since discovered skydiving and last I heard spends most of his time…   Read more»

If Joe says OK, I have the original artwork files.Warren

If you’re talking NAR, you could be right, I can’t comment there. But if Tripoli, you can take the test a couple times in the same day if necessary – I did.Warren

It was found and turned into the LCO table around 11 or 12 and I announced it several times over the PA. It is in the LCO box that rides in the trailer. You can pick it up at the…   Read more»

I personally have used a lot of West Systems epoxy, others here use Aeropoxy. One reason I use West Systems is that you don’t need a curing oven. Some of the Aeropoxy’s do require a curing oven.Hobby epoxy doesn’t seem…   Read more»

I’m sorry John and Joe, but I lack certain necessary tools to troubleshoot and fix website issues like username/password problems and editing non-content blocks like the schedule on my laptop. My main machine is still not up and running since…   Read more»

Well John, it’s about time. Been wondering when you’d do something like this.W

Let’s see, to address your questions:1) I love the EZI65, my favorite LOC kit. A very good choice.2) Aeropack retainers are the sine qua non of motor retainers in my opinion. While I’ve only used the 54mm and 98mm sizes,…   Read more»

I’m with Chris on this – dadoed slots in the airframe with relatively thin, low mass cores properly glued in, then 8 maybe 10 or even more layers of tip to tip, vacuum bagged and with a proper cure process.W

It’s not the weight for the sake of weight, it’s the moment arm of having high density, high mass fins out far from the centerline trying to lever the fins off the body. Use low mass material – hell I…   Read more»

John,I suspect you already have a 75mm VK cone from PF. My take would be to lay up low mass fins out of honeycomb and multiple layers of CF, Kevlar and perhaps glass as a sanding veil like my L3…   Read more»

I’m in John. Let’s discuss when we get together to v-bag your fins. I even have a Kevlar conical we can use.Warren

As Ed said, we have a seriously difficult time tracking the club motor cases and I would vote against the club maintaining or being responsible for any altimeters in the pool.On the other hand, if you want to maintain and…   Read more»

Let me add my congratulations Ed. Are you going to do a production run for commercial sale?Warren

You can camp out there 365 days a year if you like – just no more than 14 days in a row.W

James Russell is the usual maintainer of the CO Rocketry Calender as I recall.Warren
