Personally, I think it would be irresponsible for me to foist a design that "Looks Cool, But Doesn't Fly Worth Beans" (*That's* a terrible tag line) on the rest of you. So thanks for the specific feedback! Quote:
Okay, a *lot.* Quote:
As Craig mentioned, we're working on "getting it right" with my Tau Zero design. So just keep checking in here so you can find out *exactly* what works! Thanks, and cheers,

A C6-7. That's what works in mine. You can quote me on that.

Wall E. Coyote - SUPER genius I used a streamer with only Kevlar for a shock cord and a decent size screw eye.

The screw eye was one of an assortment that I bought at Lowe's. As for the flight, I think I was lucky. We'll see this weekend. If conditions are right, I'm going to try it again.

Tau Zero -- Screw Eye Woes
Quote:
How big is the outer diameter for the eye of your SE-14? Will it fit comfortably inside an ST-7? And how much does it weigh? (I need to add it to my RockSim data file.) Thanks, as always, and cheers,

Hi Jay!
You prodded me into doing something I should have already done! SE-10 .40" OD .95" Long 1.0g SE-12 .48" OD 1.12" Long 1.9g SE-14 .53" OD 1.47" Long 5.0g All fit the ST-7. The SE-14 is to large for ST-5. We use the SE-14 to add extra weight on several kits. At .176 oz., it is slightly heaver than the Estes NCW-1 (.12 oz.) and their small screw eye (.03 oz) combination (without the soft lead hazard.)

Eureka!
Good news! Thanks to Carl's information on Semroc screw eyes, I think I've solved the Tau Zero C6-5 instability problem I had! (And which Bill *didn't* have, apparently thanks to a beefier screw eye from Lowe's!)
I got the following RockSim results from a version *with NO screw eye!* Quote:
Empty - 4.17 A8-3 -- 1.49 -- 335' -- 23 FPS B4-4 -- 1.26 -- 650' -- 21 FPS B6-4 -- 1.32 -- 650' -- 24 FPS -- Wiggly! C6-5 -- 0.95 Marginal [1185' -- 8 FPS] With SE-14 Screw Eye (!) Empty - 4.77 A8-3 -- 2.13 -- 300' -- 18 FPS B4-4 -- 1.90 -- 619' -- 22 FPS B6-4 -- 1.96 -- 622' -- 26 FPS C6-5 -- 1.56 -- 1175' -- 14 FPS (*Not* marginal!) +++ So there I go! I just need to get some SE-14's with my next Semroc order! Quote:
