I'm running RocSim (Version: 9.6.0f202) on a new critter I'm building, an LOC I-Roc. I have the beastie all built there and with a 4gr 38mm CTI in her, I have to add 8oz of weight to the nose to get 1.9 calibers of stability. That's not even the >=2 I'd prefer. Whoa, almost 1/2 pound! I'm using the RocSim calc and sim methods. With Barrowman it's worse.
I had to add quite a bit of weight to my Minie Mag so is this just a challenge with short-wide rockets? The I-Roc is quite a bit longer but still only 55" OAL. I read that on the Minie Mag, the short / wide actually imparts greater stability with some suggesting that no weight was required from their experience. I thought, great and tried it even though I didn't very much like the sims I saw with that "phantom cone" on the tail. It was a sky-writer until it burned off enough fuel to become a TOW missile. :y: Fortunately, heading away from everyone. Not going there again as I must have misunderstood other folks' results, since mine were quite bad.
Anyone else have an I-Roc and how much weight did you add?
