How about you?

Heh, I rarely use the program myself. So, no, I haven't played with any of the new features yet.

Revised plan -- Mini Loader

From 2003...

This is another "Schoolyard Sounder", with very classic styling. The performance is outstanding, too!

1/4A3-3T......190'......3.52 FPS
1/2A3-4T......425'......7.71 FPS

The full A3-4T and the A10-3T are NOT recommended for this model; the deployment V is too high, because the delay times are too short.

First time I've run this one through RockSim. This one is going to become part of my personal inventory soon!

Revised plan -- 1971 Parts Catalog Demo Rocket

I've gone back to this design and changed the nose cone to look more like the Gemini capsule from the original. I wound up using two balsa transitions and a solid balsa piece which look like and approximate the length of the BNC-60AB.

The pod nose and tail cones are still simulated as mass objects...

It still flies like a pig...

New Plan -- Mini 'Mega

This model is a simple 60% downscale of the Estes Astron Omega. Excellent performance on 18mm motors.

B6-0/B6-6.....1115'.....7.54 FPS
C6-0/B6-6.....1540'.....10.33 FPS
B6-0/C6-7.....1720'.....19.62 FPS
C6-0/C6-7.....2110'.....12.83 FPS

All simulations show a 36" rod is sufficient for stability.

Enjoy!

Revised plan -- Tempest

This was never posted here on the forum, but there is a PDF on the website. Up to this point it has remained a CONCEPT design, without being run through RockSim. I have now run the simulation, and have some good numbers, meaning it will shortly be moved to the PROVEN page.

B6-0/A8-5......550'.....22 FPS
B6-0/B6-6......790'.....30.2 FPS
C6-0/A8-5......900'.....10 FPS
C6-0/B6-6.....1120'.....22 FPS

This model uses a paper shroud, similar to the Laser-X. The upper body tube is hidden behind the shroud in the simulation, but on the model it would be there...

Enjoy!

Revised plan -- Triton

Another plan from the CONCEPT page on the website...

This is a three-stage model, with a wide range of motor combinations to reach anywhere from 935' to 2400' altitude. All SEMROC components.

This model requires an 8'-10' launch tower for safe flight.

B6-0/B6-0/A8-5......935'......9 FPS
B6-0/B6-0/B6-6.....1217'......4 FPS
C6-0/B6-0/B6-6.....1495'......10 FPS
B6-0/C6-0/B6-6.....1585'......20 FPS
C6-0/C6-0/A8-5.....1620'......29 FPS
B6-0/B6-0/C6-7.....1770'......26 FPS
C6-0/C6-0/B6-6.....1875'......15 FPS
B6-0/C6-0/C6-7.....2140'......18 FPS
C6-0/C6-0/C6-7.....2400'......18 FPS

Enjoy!

Revised plan -- Deltoid

Yet another revision of an early plan, the Deltoid was loosely based around the Boeing Delta and the Custom Serval. This model has a good power range, from BP D12 to AP F21.

Important note -- When using either a D12 or an E9, you need to use a 48" launch rod. All other motors have sufficient impulse to achieve safe flight velocity on a 36" rod.

Power settings:

D12-5.......690'......16 FPS
E9-4.......1080'......29 FPS
E28-5......1280'......24 FPS
F12-5......1470'.......2 FPS
F39-6......1480'.......5 FPS
F21W-6.....1675'......23 FPS

Enjoy!

Revised plan -- Minotaur

One more 2003 design brought up-to-date through RockSim...

Big, burly payload lofter capable of decent performance. Skill Level 2.

Power settings:

D12-5.......590'.......12.0 FPS......48" x 3/16" rod
E9-6.......1040'.......20.0 FPS.......8' tower
E15-7......1600'.......17.0 FPS......48" x 3/16" rod
F24-7......1810'........5.2 FPS......48" x 3/16" rod

Enjoy!
