Powered by four 8" Q motors; surrounding a 12" S motor.

So... 64 or so? Yikes!

Lots of people brought their own pop-up canopies, but the wind was enough to wreck a good number of them.

Some launching Friday and quite a bit on Saturday. It was 100+ degrees and windy enough...

There's a big difference in how a mid-power launch feels in my opinion... It's much louder and more dramatic. Honestly, I think the change comes partly from bigger motors and partly from the...

What to do with the others? Remove the ejection charge and stick em in a 29mm art applewhite "rocket" that uses tumble recovery. I always wanted to see a Scimitar on a G80... :-)

Hey, thanks guys! Now I just have to decide on a paint job... :-)

I just bought the Wild Child deal with the Cesaroni casing, and this is my first fiberglass rocket. I want to be sure to order the right retainer... Aeropack has three 29mm retainers designated L,...

My opinion: Skip any smartphone altogether. Buy a phone whose sole purpose is, you know, being a phone. There's usually 2 or 3 that they give away for free with your contract in the stores.

I had a Thumper Jr. (5.5") on a 38mm mount and was uneasy about using a lot of the smaller 38mm engines -- The finished rocket is fairly heavy after adding the weight to the nose and so on. If the...

They certainly don't need epoxy. The only area that tends to take abuse is the fins, and the plastic will break before the CA glue gives out. (We had an Initiator stick a single fin in some soft...

I have a dremel and the drill press attachment... It's not a replacement for an actual drill press. Dremels have very high speeds and low torque -- You have to press more gently, but the heat from...

I've come across copperheads that can't be fitted through the nozzle on the the 29mm hobby line engines, but they're the exception rather than the rule... Generally only happens if there's some oddly...

1. Dual Deploy. I built my L1 rocket to be DD, but just did a regular engine deployment for my cert flight. Now that that's out of the way, I need to go ahead and try DD. :-)

2. Go to LDRS.

For me, the "standard" first-MPR-kit is the Aerotech Initiator.


It's ubiquitous... Just about everybody seems to have an AT kit
It goes together easy and fast
It's an extremely fun and...

MS offers a free compatibility pack for Office XP, 2000, and 2003 which gives them the ability to open up the newer Office 2007/2010 format.

Incidentally, the newer format is actually a zip file...

Oh, and then there was my other (less successful) L1 cert flight...

Thumper Jr.
I think the rocket was on the way down before the delay burned through, and the powder moved away from the delay...

Scratch built 2.5" rocket set up for dual deploy, but I haven't actually used DD yet. L1 cert flight was on an H123 (38/240). Altimeter read around 2100 feet.

The picture is from the second...

Does this make me an embracer? You can't see the spiral dimple because it's on the edge of a color change ;-)

12,551 :-)

I was able to make something that looks mostly right, but it looks tough to make it stable without the whole invisible fin thing.

As I understand it, the voltage on an AA with no load may be as high as 1.6 volts or more, but with any sort of load on it (for instance, charging the camera battery), the voltage will typically drop...

With a reasonably standard rocket, you could do this in rocksim and probably the other less costly alternatives too. With a spool, I don't know that I'd trust any of the answers from a simulation. I...

There are lots of car->usb charger devices, primarily so people can plug their ipods in while they drive and whatnot, but it should work for this too, and it ain't gonna make a dent in your car...

I've ordered from them and I'm all the way down in AZ. Takes about a week normally... Last time I ordered, all the motors were listed as out of stock, and we still received all the motors except for...

Hoax. Mars and Earth pass relatively close every couple years, and every couple years, we get the same emails about how it's the closest in 10239349 years and mars will be the size of the moon. So...

Ah, clever! I was thinking of teflon tape.

Out of curiosity, what are your opinions on the middle road -- rail lugs rather than buttons?

It might be an interesting option instead of a spill hole if it turns out to be too porous... An 8" hole in the center covered with tulle rather than a 4" spill hole or some such.It'll be interesting...

I just did this with the LOC 2.5" coupler which is 5" long, and it seemed awfully tight with THAT... But then again, I've no experience with getting a lot of electronics into a small space. I...

Can we expect a 1/2 scale for your L2? ;-)

PML has a 1/2 scale kit...

Hmm, I'll have to see if maybe I can find some thin rubber foam to line where the bottom bulkhead goes.

Incidentally, I launched Jack Skelerom for fun once the cert flight was out of the way....
