Is it possible there is some error in the data for these two motors? Rocket Reviews and Open Rocket state that the Quest has a total impulse of 12.68 and a peak thrust of 22.275, see https://www.rocketreviews.com/q-d16.html, while the Estes has a total impulse of 16.84 and a peak thrust of 29.73, see https://www.rocketreviews.com/estes-d12-5112.html. Accordingly, my Open Rocket sims show that my rockets will fly about 25% higher with the Estes D12. But that's not so, at least not for me, my rockets consistently fly substantially higher with the D16.
What am I missing?
Thanks,
Bill
