The ST-6 is my own creation -- it doesn't actually exist yet. I needed a tube to use as a motor tube for the 15mm, so I created those specs to "fit" the motor casing with similar play to the ST-5 using the 13mm motors. OD = 0.620" ID = 0.594" Wall Thickness = 0.013" (Same as ST-5)

New Plan -- Whippit
Here's an example of what we could be doing in the area of two-stage models once we get the booster motors. This design is tweaked for 10mm motors.
Length: 23.45" Diameter: 0.908" (ST-8) Fin Span: 4.41" Weight: 1.105 oz A8-0 | 1/2A6-5......430'......Dv 25 FPS A10-0 | A8-5........700'......Dv 2 FPS A8-0 | A10-5........724'......Dv 12 FPS A10-0 | A10-4.......750'......Dv 22 FPS A8-0 | A3-5.........755'......Dv 5 FPS A10-0 | A3-5........780'......Dv 5 FPS The model qualifies as a "Schoolyard Sounder" by using motors 13mm or smaller [I may allow 15mm motors here, but not just yet.] All motor combinations reach flight velocity on a 36" standard rod. Enjoy!

Micro Hustler, Take IV
Better results using the most-recent motor file...
Length: 16.3" Diameter: 0.998" (ST-9) Fin Span: 4.875" Weight: 0.83 oz 1/2A6-3......121'......Dv 15 FPS A8-4......358'......Dv 3 FPS A10-4......413'......Dv 4 FPS A3-4......421'......Dv <1 FPS Thanks for the great design, David. This is going to be a popular model when those motors finally come on-line. I like this one!

Updated Semroc Motor File [Preliminary Data]
Version 4. I added the Quest A6 and B6 sizes to the 10mm and 15mm lines.
Same installation instructions as before.

All of my engine files are accessed as .eng files. Am I missing something? James |

What you have are RASP files. If you are using RockSim versions 7 or 8, you can import ENG files into the EngEdit program and convert them to RSE (RockSim Engine) files. RockSim reads RSE files only, but the Engine Editor program is where you create new engine values, or (as I'm doing) modify existing data files to appear as the new motors.

Interesting, as there are no .rse files in my Data folder except the Semroc files you provided. I am using RockSim version 7. I do have an RSEngine.dbs file, though. Nothing happens when I open RockSim and select File>Reload engine data. James |

Interesting. Apogee must have made a change between 7 and 8. I use version 8, and just had it updated in the last week. Let me look into this, and I'll see what can be done.
