New Plan -- Tau Borealis
 

I don't remember if this model name was requested by anyone (Jay?), but it just came to my mind today and I noticed I didn't have one already in the line-up...

Here's something just familiar enough to be called a sibling to the Andromeda, but not exactly the same to be just a copy. This is also another (in)famous Cracker Barrel sketch come to life. It's a "Chicken & Eggs, smothered in white gravy" design. (There's a scarry bit of unrequested extra information for ya!)

Length: 22.44"
Diameter: 1.64" (ST-16 shrouds)
Fin Span: 3.76"
Weight: 1.52 oz

A8-3......180'......Dv 7 FPS
B4-4......443'......Dv 6 FPS
B6-4......451'......Dv 10 FPS
C6-5......976'......Dv 12 FPS

All motors reach flight velocity on a standard launch rod.

Enjoy!

"Mr. Borealis? --Meet Miss Aurora..."
 

Nope. I'm *so* into "Aurora," though... :eek: :rolleyes: ;) :D

Okay, for extra credit (Bill?), identify the "fabulous" 80's song this quote is from:

"Aurora comes in view..."


(--That means she shows up. *Not* the alternate meaning. :eek: :o )


Chuckling,

A Flock of Seagulls.......the group.....oh, but you wanted the song........I ran........

"I Ran," sang the Flock of Seagulls...
 

(Announcer's voice) "Ladies and gentlemen, Don Barone takes home ALL THE CANDY!" :D :cool: ;)

Thanks for playing. :D


Cheers,

AFOS reference! Niiiiiiice.

<WARNING - GEEK ALERT>

What's really scary is that I have a picture of me on stage singing with Mike Score (lead singer) at the end of a Seagulls concert from the 80's...

Did you have matching hair-do's? :D

Thank God, no.

What most don't know is Mike's "tailfin" hair-do was probably the world's most elaborate comb-over. By the time the concert I was at (later 80's, after their prime), he'd mostly lost it all on top and had the "bald-mullet" .

New Plan -- Tau Cygnus
 

It's been a slow January and February around here...

This design is another in the (in)famous TAU series, and draws some influence (OK, maybe more than just "some"...) from the Andromeda. It is a simplified model, but it retains the family styling with the reactor shroud and coils, the open fins, and the stylish nose cone.

Tau Cygnus also fits into the VR Class with its under-800' altitude on a C6-5.

Length: 23.95"
Diameter: 1.64" (ST-16 reactor shroud)
Fin Span: 6.04"
Weight: 2 oz

B4-4......330'......Dv 13 FPS
B6-4......340'......Dv 8 FPS
C6-5......787'......Dv 7 FPS

The A8-3 is not recommended as it does not reach safe flight velocity on a standard rod, and only attains about 125' at best. All other motors listed reach flight velocity in the length of a standard rod.

Enjoy!

Need RockSim Help
 

OK folks this one has me stumped. Flight simulation says it won't leave the rod and 2D profile shows it starting parallel to the ground (launch rod @ 0 degrees). Did I miss something? Software problems? Any help would be appreciated.

Look at the fin thickness of the rocket image when you prepare for launch to load a motor or view the line diagram in the 2D base view of the design.

It's your fins. I'm assuming that you wanted 0.09380 instead of your 0.9380 for the thickness of the fin material since these fins are almost an inch thick? You also selected "custom" for the fin material and that has a "zero" mass for the fins. Instead choose balsa or one of the other materials.

I changed the design to balsa and 0.09380 for the fin thickness and it flys fine.

The 3D export did look kinda cool ..... :)
