The Thrifty Rocketeer blog continues...
Most of us have flown an Estes Rocket kit before, and so we are familiar with the small blurb on the packaging and certainly in the instructions that cite two or three motors that the model will fly on.
It's my understanding that these motors are:
- Currently in production (at the time the kit is produced)
- Designed to "fit" in the unaltered kit, and
- Tested in "Open Rocket" or similar RocSim program
Now, if you've deviated from the plans, or made a special modification, you're gonna have to factor those changes into the rocket simulation program and see what it recommends for your motors to effectively fly the bird safely.
At least, that's my understanding.
If you go for the upper limit right out of the box, you may loose sight of the rocket, and may never recover it. I know this doesn't seem likely, but a second respondent also agreed, saying they lost their first two rockets by ignoring the first flight recommendation and going for the limit. By their third rocket, they had learned their lesson, and never have lost a rocket since.
