I have been wanting to build a staged & clustered rocket for a while, and with Estes sales, I thought I would try it with mostly off the shelf rockets. The plan is to have a PSII booster acting as the 'anchor' of the system, not only acting as a booster, but as the lower support for the booster pods, which will be on little rails as to slide off the sustainer at second stage ignition. I had wanted to use the two Orange Crush rockets for boosters, but with the 3 fin design of the Mammoth and PSII booster, I had to shrink that down to a BT-55 tube instead. First stage will be 2xD12-3's and either a E16-0 or and E12-0 (with adapter) followed by a single F-15-8. My hope is to provide enough thrust with the boosters to make the PSII system take off at a better speed.
Rough sims currently have it going to ~2200 feet and 30 FPS off the rail with the E16-0 (which seems close to my stock Mammoth sims for FPS off the rail) Sims with the E-12 go to ~1900ft and 37 FPS off the rail.
Stability seems good at 2.6 with most items accounted for. Weight seems to be the bigger issue, and is holding down launch speeds. The E-12 gets off the rail faster, but E-12's seem to go boom a lot.....
I need to get a Chute Release before trying this, but I was wondering what your all thoughts were.
I will try to post pics when they are worth taking.
