This is a 2 stage rocket design o' me own all made from 3” Blue tube. Blimey! T' First stage booster has two 29 mm engines and t' 2nd stage has a 38mm engine. Begad! It’s duel deployment runnin' a Raven 3 with a RockeTiltometer , shiver me timbers, all that in a 3” tube is a lot but can be done by usin' both sides o' t' sled. This is quite t' most complex rocket by far I’ve built. I’m findin' out that Rocksim is havin' a hard time with t' booster. When unloadin' one engine it still shows me t' results as if both were loaded and I can’t get a good feel for what loads would be safe if 1 didn’t light. I Finally decided that I’ll use 2 CTI G250 two grain VMAX motors in t' booster and Aerotech H245 in t' second stage. I’m goin' t' fly it without t' booster first with a I218R t' make sure it flies straight and we’ll go from there. Pucker factor should be high!
This is me first flame job and I was very happy with it, nay bilge-suckin' t' be done with spray can paint! I think it will look really hot on t' pad!
Weight Dry W/booster - 86 oz.
Weight Dry W/O booster - 72 oz.
