Hey, everyone! I'm going to be getting a kit for a 3" Dual Deploy Twitch from Madcow Rocketry for my L2 cert. Here's a link for reference: https://www.madcowrocketry.com/3-thin-wall-fiberglass-dual-deploy-twitch/

Unfortunately, there is no RockSim file listed on their website for that particular kit. I was hoping to use the simulations to help me choose a motor for it. Does anyone know where I might find one, or one similar enough to approximate with? If not, any advice on choosing a good L2 motor for the design would be great as well.

Thanks!

-Josh

Along these Rocksim lines, I have been searching to no avail, for information on the thin wall FG parts to add to Rocksim.
Can anyone assist?

For simple motor selection and delay calculation purposes just put the weight, diameter, and a guess of the Cd into thrustcurve.com.

Thanks for all the replies, everyone! I'll take a look at all my options and decide from there.
