Hey all-
Okay I know this is kind of a lame question. There is a reason why I am asking the rocketry community this question. ANYWAY..
If you have a dual deploy 3" MAC Performance Scorpion and have done some flights on it with 38mm motors...can you let me know what motors and what altitudes you got? Its that simple.
I am thinking of trying an I200-W (YES I said I200....I love that motor. Based on dry weights and adding a pinch for glue and paint I get a thrust to weight of around 6:1 for the life of the burn of the motor...not bad) for lower flights and the I284-W for higher flights (which may be a tad out of site....to much for me since that motor is almost a J motor). All I need is some rough ideas on motors and altitudes for this rocket....so I can get a general feel. Kind of like asking folks at the launch line "Say...what motors have you used in that rocket".....thing. Since I dont know anyone with this rocket...I go to the forums...
Back Story: So, I dont have Roc-Sim...Open Roc makes my computer crash, and I did go to Thrust Curve.org at one time....See, I have a 4" Scorpion that I entered all the actual weights and measures on the ThrustCurve guide. I entered my motor...a J540-R. It said a max altitude of around 4100 feet. When I launched it....it went 5289 feet (sweet). Just a little off though!! So now you know the boring back story to my original question. And since Thrust Curve says "Simulator Data" on the thrust curves I am looking for more real world, observed information on this rocket.
Thank you for your time and Help!
