Look for post number 50295

If that is the going price, can I assume correctly that it is no longer available from Estes (at a more reasonable price)?

And if it is out of print, has the copyright expired?

And if someone...

If so, I suggest keeping your rocket design subsonic (probably gonna start encountering transonic effects beyond M .9 to .95, depending on your design) and avoid the supersonic wave drag problem...

Sounds cool. I don't have any of your products so I am not familiar with them, but the "XS" version sounds like something I would be interested in.

Don't mention this to any of those guys over on the "intellectual property" thread

(Oh, wait....aren't you one of them, Larry?)

To work a design like the Estes OT you could continue with the "root attach" masking. You are gonna have to measure out where the nacelle pieces fit onto the wing panels and then mask off those zones...

A lot of good advice posted, a big thankyou to you guys who shared your experiences

I glue balsa fins to the rocket first.

The way I see it, no matter how pretty (or ugly) the fins end up, they don't do any good unless they stick solidly to the rocket. Also, once the fin is glued...

First vid made me laugh out loud.

Second one made me vomit.

If you need the absolute best chances to find a rocket during descent or after landing, I have found that adding a long skinny silver streamer to the recovery system is very beneficial. Obviously you...

That's just at the "big" launches.

Scratchin' my head, can't remember the name of it, but didn't Estes have a RTF modroc release a couple years ago that used this recovery system?

I agree with these other guys, the 3-ply should work fine (heck, basswood would probably be OK).

I suggest that your fins would be "a little bit" stronger if you lay out the fin leading edges to...

But not on a rocket.

Your post sounds very very familiar. Change a few details and it's much of my life story too. (And I'll bet it matches quite a few others here on TRF too.) I have raised three kids, and none of them...

That number itself (the "100,000") is questionable; I have seen other statistics, it's hard to know which one is accurate.
