In all seriousness, I could never compete. I have re-engineered nearly every rocket I've built. I move launch lugs around, split them in two, make them longer (or shorter), and bevel the ends, if not for aerodynamics, then for aesthetics. I'm sure I'd get clobbered on scoring

I also change the motor mounts, completely revamp the recovery systems, and modify the paint and decal schemes, such as adding the D-power decal to my Camroc booster ('cause it was D-powered).

And I'd readily drop a big block into some 6-banger 1967 Camaro regardless of whether it was a "numbers matching" car - we don't need to stinking matching numbers

You got me thinking.... A body tube from an Estes Alpha. A nosecone from an Apogee Avion. Fins from a Fliskits Thing-a-ma-jig. Launch lugs from a Maxi Alpha. A motor mount from a Quest Astra 1 (insert carefully!).

A real Johnny Cash rocket that could be entered in just about any classic model rocket contest.

WITCHCRAFT! WITCHCRAFT! DavidQ weighs the same as a duck!

It's a 50, 51, 52....

You describe a different animal, a SPEV, which is a category unto itself (that probably doesn't get enough respect )

That said, we've seen plenty of stuff launched at the cape over the years that, in many cases, looked to be thrown together - Little Joe, anyone?

So why should cadging a few disparate parts together into some sort of make-believe rocket be any less legit, eh?

I guess I need to build me a Little Dougie

Here's where I've mounted it: on the EH line and the bottom of the LL is 1.625" from the rear of the BT-50. The LL itself is 1.25" long.

That ought to work.

The launch lug on the Alpha (and the body tube itself) are the only individual parts that have been unchanged for the whole 52+ year run of the Alpha from the first K-25 to the current version of 1225.


Love David's comments.

As to Astronwolf's: The judges in Classic Model, as in other craftsmanship events, use the data provided by the contestant against which to judge the model. In Classic Model in particular, it's the catalog or face card illustration that they mainly go by (or so it was at NARAM-60). Most of these don't even show a launch lug....

Doug: As near as I can tell the judges at NARAM-60 didn't look inside - or they would have seen the length of kevlar I had between the shock cord mount and the rubber shock cord in my entry. There are no judging criteria for the internals....it's how well it matches outline and color on the outside that they are looking at.

Looks good. I approve of the way you align the launch lug and the motor clip. That is my preference to do too.

DavidQ's "overly technical" description is incorrect even if it's "artificially precise." Such a rendering ignores the two illustrations on the first page, and in the second illustration of step 7, where the launch lug appears to be in close alignment with the motor clip. The first illustration in step 7 appears to suggest placing the launch lug in a position on the body tube 180 degrees opposite of the motor clip. But in step 10 it appears as DavidQ's imprecise description suggests. My attempt at sarcasm seems to have flown the coop when I suggested the launch lug placement had anything to do with which two of three fins were important for launch lug placement. The best answer seems to be, "it doesn't matter which two fins."

Having judged classic model maybe a dozen or so times, I usually ignore the launch lug except when inspecting the model for "craftsmanship." But if I can see a launch lug in the entry's data packet, I may include its placement when evaluating "similarity of outline."

Apologies for seeming to lecture someone from whom I should be learning (especially my bit about what's in the data packet). I've only been a contestant a couple of times, never a judge.

I do more learning from your posts, that's for sure.
