Unhappy C11s are gone ?

The C11s were my favorite motor to use. The KNO3 (Potassium Nitrate) Estes has been using is so impure that rocket motors of 25 years ago seem to have double the lift capacity because of the pure KNO3 they used.

Today's A8s are so weak they need to be MESS surveyed after every use. Based on visual observations from old timers, the C6 lack the power of their 1970s counterparts. C11 solved this. New I may switch to AT C14x to fly some of my rockets.
