There is initial information over in the Rocketry Deals Forum on this rocket. Amazon keeps selling the Estes Der Big Red Max kit (3" version of the Der Red Max) for $21.99. I ended up with a number of kits.... then got this idea and got some more...
So this is a quick (hopefully) build thread for this kit bash. I do hope to keep this light enough to fly as Class 1, BUT with (3) 29mm Motor Mounts, and the overall size, the HPR Forum seems a better fit.
I did a bunch of copy-paste out of @K'Tesh OR design file for the original DBRM. My KitBash of 3 into 1 seems like it will work... Maybe even keep it class 1 if I can keep the glue amount under control...It sims OK on (3) F15-6 motors with a 7' launch rail. 850ft apogee. (4) original Skull & Crossbones parachutes.
[ NOT Class 1 with (3) F15's, it's over the 125gr propellant mass limit. It CAN use (3) Aerotech Composite F or G motors and stay class 1. (3) F42-Blue Thunder motors with a 6' launch rail. 1050ft apogee.]
Screen shot of initial SIM and OR Image. (Final SIM file will be posted at end of Build.) [If anyone wants me to post the initial version let me know and I can...but it's rough.]
