Long post and kinda jumbled.
I'm at work, in and out of meetings prepping for some classes, so bear with me. I'm on my phone with no access to OR.
First file I posted was mid December and received zero input. Now everyone wants to jump in with ideas and suggestions.
Where were yall last month when we were trying to decide what to fly? LOL.
This ORK file was my latest design idea and now it is getting the comments and participation that I have been looking for. It will be tweaked, I only just now received all the parts. And it can be changed. I am open to ALL suggestions for airframe length and fin shape. I can cut the fins down but I can't add to them of course, but once they're mounted that will be it.
Airframe is cut at 9", the cutoff is 9" as well, more than willing to take it down to 6 or 7. I can lighten the rings and take some out of the fin tabs to shave some weight.

You haven't missed anything. I was only assuming most folks had at their disposal a shorter rod so I set that purposely short. Some of those motors are unacceptable and they are not recommendations but simply showing what I have simmed. But having them in there has opened up a line of communication that will help finalize the design. When it's built and ready to fly the sim will be finalized with weights and stability then I can recommend motors.
NAR requires only .5 CAL. I fly many well below that, albeit short stubbies. But for a rocket at 9:1, I have no problem flying it between .5 and 1 CAL.
Thank you for working on the sim. I'm at work and getting stuff ready for some classes with no access to OR.
I found anomalies when I added one inch to the airframe. Stability went up but altitudes went way down, some even returning large angles of attack.

Therein is the dilemma of this project. Keep it light for small motors and reduced shipping, but built with fiberglass, and can't go too high on readily available motors, oh yeah, it has to be stable.
@jbrracer
I'm there with ya. Most of the motors I fly are bigger than this rocket.
@DeepOvertone flies with me here in Louisiana and we have been texting back and forth. He is looking at the file since I can't while at work. Sweeping the fins appears to help quite a bit.
