Open rocket file

Hi, anyone have the OR file for the super viper? I upgraded mine to take 29mm motors and made the nose cone adjustable to add weight. More rockets was no help, just do the swing test
Kit comes w 30g clay weight
Weight 0.4lb ( no motor)
CG 16.5” from nose cone

and my body tube spirals, came

Who's kit? I'd check the vendor's site or send them a message asking if there is an OR or RockSim file.

If you've not designed a rocket in OR, that one may take you some time. It should be quite stable with the large fins coupled with the those tubes acting as fins. Of course, it's likely all that moves the CG toward the rear too. Was nose weight needed in that rocket?

A swing test is fine for proving stability; however, with OR, you can predict apogee and thus, nominal deployment delay time. I'm surprised that MoreRockets doesn't have an .ORK or .RKT file for that.
