L1 in my future

If you want a bit more confidence, do 2-3 simulations with your rocket - with 5mph wind/low turbulence, 10mph/moderate, 20mph/high. Make sure your chute is correct in the sim. Print flight side profile for each and keep with the rocket...

Come launch day find those printouts, check wind speed - and the map:

I will certainly do that Alex. What are the units on the map?

And now for some final bits:

1. Shear pins. I have a bunch of the small (2-56 X 1/4") nylon screws (ordered from Apogee). Considering whether to use 2 or 3 to secure the payload section to the booster section of the Super DX3. My concern is that I have no way to test whether this will work (specifically whether the motor ejection charge is of sufficient strength to snap the pins). Wondering if I might bring the DX3 to an upcoming launch and enlist the help of someone with a supply of 4FFFF powder for some ground tests? From what I read, they are recommended, and I can see why...

2. Nose rivets. I don't think the nose is going anywhere - the tape friction fit is pretty tight, but thinking of installing some plastic rivets (also on hand and obtained from Apogee). Of course, once this rocket is converted to DD, I will have two unsightly holes up top if I do so, so I'm leaning towards not doing this.

Appreciate any thoughts on these matters.

Thanks,
