Anybody building anything?

I have a couple projects going. Aside from the usual winter repair work. I want to get my Estes Commanch complete for a 3 composit motor staged flight. Flew it last weekend on a D21, its setup for dual deployment, worked great,

1300'. But the motor bonded to the MMT and when I went to remove it pulled the whole mount out.

I also have a rocket I dubbed the Orient Express that I will fly at LDRS. Here is a link to it.

12in dia, 15feet tall. Working on assebling the fincan now.

I also just got a GPS for my Hyfly III, I will add this to the computer and log that too.

want to make two M flights of it at LDRS.

ok so I was rushed a bit to get moving. I missed a few Rocket related projects.

I need to redesign my Hybrid launch equipment to make it easier to use. I need to finish assembling my MSP430 based altimeter so I can start programming it. I have a new timer to assemble and test. I also need to complete testing of an altimeter that uses a different pressure sensor then I have been using. I have two other altimeter concepts that I am investigating, thoes eat into my time. I might even find time to do more testing of my tracking/telemetery transmitters.

Then if I get a wild hair I will build an adapter to mount my 4in Sandhawk to my 7.5in Hyfly III so I can fly it two stage. Minus the computer ballast of course. Speaking of which I still need to build a couple antennas for the network downlink for the computer and get thoes tested.

I just wish I didn't have to sleep. RDH8

I'm working a couple of paper model conversions: A Thunderbird 3 and a Thunderbird 1.

There's also an estes DOM JPZ-1 Shuttle project going that I need to turn nosecones for.

Bob I've got THREE already!!!!!!!! And 7 other 7.5 inch rockets using 30 inch tubes:-)! LOVE those short and fat rockets! Hmmmmm.....maybe a 5.5 inch Warloc?

Won't you be jealous of the cow?

I'll get my coat...

Hey, cool! I am building one too. Mine will be painted and decaled like the newer, modern Big Bertha (black with white decals). And mine will have a 3" mount.

Drag race at LDRS? ;)

A couple years back I grabbed a handful of Quest Lightnings at the Hobby Lobby Half Price sale. These have turned out to be perfect Fire and Forget rockets for E9s, F20s, etc except they keep coming back. First one has flown on F20 and F23. THe F23-7 flight at NARAM-44 in McGregor couldn't have landed more than 50' from the pad. And another with a 24mm MMT was used in E SD at NARAM-45 this summer, and was recovered after both flights.

It's got a 4 inch

Sheesh, with all that work into it, paint it yellow/red/black/white ranger:

Actually, I only did a single motor in each stage. The combo was F50-4/D12-3/C6-5. The problem with the flight was the electronics, not the wind. For some strange reason the circuit decided to start timing at apogee, not liftoff (a reset pin was removed at liftoff), so both the

2nd and 3rd stages were pointed earthward when they ignited. The upper stages were trashed, the first stage was still okay.

That had to be 5-6 years ago. I've been working on a new one since then, with different electronics. Maybe I'll get it finished sometime in the next 5-6 years. After that I'll try the 5-5-1 version :) :)

Rich Sounds great but we may have to wait until BUFFROC. Not sure if I'll have time to fly anything at LDRS. I'll be too busy keeping the rest of you guys in line:-).

Bob Can't do it. The fin slots are already cut:-)!

Ted I go back even farther than that! I'm looking at using the paint schemes from the' 66 and ' 67 catalogs:-).

The nice thing about this hobby is that sometimes, even the failures make for a spectacluar flight.

I'd love to see the one you're working on fly.

We need a name for it.

"The probability of successfully recovering a rocket is inversely proportional to your desire to get it back."

Kaplow Inverse Desirablity Principle. Not a good acronym, but catchy. Reciprocal Rocket Recovery Rule. Mmmm, acronym too plain. Reverse Effort-Recovery Relationship. I'm stuck in the R's.

Aw, there's probably a name for it anyways.

In general, this principle is known as the Non-Reciprocal Law of Expectations:

As soon as you think about something:

If it's good, it goes away. If it's bad, it happens.

:-)

Ahh, the Ugly Rocket Rule. The uglier the rocket, the more probable it will be recovered. The formula is as follows:

Percent chance of recovery = ( 1 / Ugliness ) * 100 ugliness is on a scale from 1 to 10, 1 being butt ugly, 10 being museum quality.

Note: this formula is only an approximation, it does not hold true at relativistic speeds.

Epoxy filler!
