Thank you! Had I known I was going to do the swap instead of a booster, I would have made those fin tabs longer(wider in length). If I can do this I'm very comfortable now building my L1 cert flight rocket for sure!coming along nicely
Yeah well have a little issue I just found....ugh. Ill get this taken care of, and respond later to all you said... lol..I don't think you'll have a problem with your setup as long as you don't go with a stupid powerful 29mm motor. Those large Big "B" fins could be prone to flutter under high velocity but I think your poster board reinforcement might be enough to prevent that. Back in the day I'd go with .75 ounce fiberglass cloth and laminating epoxy. That is such a PITA to do and is time consuming. Also would add more weight to the aft end than your method. Are you going to sand the leading and trailing edges?
If not, the drag might be good to keep the apogee down if flying in a smaller launch site. Just paint 'er up nice, make sure the fully loaded rocket is within CG limits and let 'er rip. Make sure you base the delay grain time on multiple simulation runs if not using deployment electronics and know how to drill a delay to get the time to where you want it.
Drop in a Jolly Logic chute release and you can have what I call a "pseudo" dual deploy rocket. "Pseudo" in that one is not using ematches for both events. Use the motor to blow the "parachute pack" out and let the JLCR let it unfurl at a lower altitude.
For first flights, I'd use lower impulse motors to see how the rocket behaves with a full "in sight" flight and increase from there to whatever you're comfortable with. Best of luck. Kurt
Ok, yeah this was really a booster idea that turned out so nice I thought why not swap it. Its a 10 year old build and I expect this to be a little off. Now that I'm dealing with the coupler issue(which is totally my fault and I've changed how I assemble them and have for some time) I had some time to write back. I'm going to start it out on something very small, honestly probably something to just take it up high enough for a successful flight. Ill mess around with OpenRocket first to see what simulations say with what motors I have. But like you said I'm not going to be putting any ridiculous motors in this. I have an adapter that I use for some of my builds(29mm to 24mm). It allows me to go fly them locally and then put something bigger in them for club launch days. But im dealing with that little inconvenience, which is being fixed now. I do have a JL chute release and will probably use that if I do get into higher impulse motors, but I'm going to be taking it very easy with this. Its more a low and slow rocket now, but with the capability to do more.I don't think you'll have a problem with your setup as long as you don't go with a stupid powerful 29mm motor.
