K805G Data (RockSim)

File Notes

Not K805G but designated K715G-P J Brent June 28, 2008

The K715G is a 1719 N-s motor; based on research data from 11-26-07 (preproduction). This is a 54/1706 motor. Data source was D.B. at AT. Weight data was assumed to be same as K805G since this was not provided. I will inquire with AT if this was a right approach and why the difference between the burn times (K715G at 2.4s and K805G at 2.2s).
