Hey gang:
I retired recently and am bored out of my mind. This Covid thing is killing me, figuratively. Not sure where the spark came, but I thought I could kill some time rekindling a passing interest I had many years ago.
I've designed, and am building a standard engine (18mm) rocket.
It is costing me a ridiculous amount of money. You can't just buy enough of anything for just one rocket. I realized mid stream that I should use 24mm body tubes and not 18mm. Accidentally ordered the wrong size of a couple things. Ordered a lot of tools, half of which I decided not to use. I've changed my mind so much, half the stuff I bought may end up in some drawer or the trash. Could have bought ten kits for what I have invested.
I stole my fin design from Boeing. Sorry Boeing. Seem big, but should do the job.
I do have a couple questions:
How do you use tracking powder?
Looking at the stats for Estes engines, it looks like the C5-3 is more powerful than the C6-3. From my understanding of the number system, this shouldn't be right. Am I wrong?
