Also, KISS III when fully loaded with 'fuel', 10 liters of peroxide, plus the extra plumbing/pressurant tank weight, will weigh about 30 more pounds at liftoff compared to KISS II. The gross liftoff weight (GLOW) of KISS II was about 51 pounds, and KISS III will be about 80 pounds. Thus, we wanted to increase the engine thrust to ensure sufficient velocity at the end of our 24 foot rail. The thrust of the KISS II engine was 300 lbf., and we wanted *about* 450 lbf. for KISS III.
We saw *about* 430 lbf. during our last test, even with excess plumbing and bends that won't be part of the actual flight. So, we declared victory and plan to fly in November.
