Estes makes a nice kit, no doubt about it. Sure, their a few issues here and there, but by and large...nice kits. I'd be a little disappointed if that part went away, but not entirely sad. We have lots of good companies producing LPR kits, and enough resources for scratch building. It would be nice to see Estes introduce some new ideas, "bring backs", and less models with the same plastic fin can. But really, if they quit supplying kits all together, it wouldn't be the end of rocketry. If they are completely doing away with rocketry items, ie motors, then we will surely feel the hit. But only for a time. It opens the door wide open for other companies. Dollars (generally) spent on Estes motors by us, can be redirected and pooled to other ventures. The sport is here to stay, it's just a matter of how it will evolve given the available resources. IF we are indeed seeing the end of Estes "rocketry", then it's a shame. But the, "take my ball and go home" attitude would be par for the course.
