So glad you started a thread on the build. There were no instructions on this model nor a sim file as I'm told it's a new model. I was going to start a thread on my build. I also created a sim file which I think is very accurate on dimensions and weights for mine but I used the override function. Here is my file:
https://www.dropbox.com/s/hf130x481hip7uz/AMW Bigger Daddy from Toby.rkt?dl=0. And here are all of the weights of my components in grams to compare to yours. They are all pretty close. Seems irrelevant if you are also adding 1.5 pounds of nose weight!
AMW Bigger Daddy
Body Tube 360g
Nose Cone 385g
Nose cone aluminum tip 33g
Nose Cone Coupler Bulkhead 34g
Nose Cone Coupler 179g
54mm Motor Mount 108g
Fins (x4) 309g TOTAL
Centering Rings (x2) 25g each
Total dry weight 1458g (3.21 pounds)
I'll follow your thread and may start my own. I don't want to hijack yours. Just trying to throw some comparative info in if it helps.
I'm planning to launch mine on a 38mm H123 with an adapter for my level 1 cert on the first Saturday of February 2018. It sims to 1250 feet which I think is low enough to launch on a single parachute, although I do have a Jolly Logic chute release. On an I motor it sims to around 2500 feet. I would very much like to see yours go mach 1. Please continue to post.
