I’m getting ready to fly another 2-stage 38mm record attempt tomorrow. This one is using my heavier sustainer since the lightweight nosecone I made for BALLS last year is in need of repair, and I’m probably going to be maxing out the waiver as it is.
The motors are an AT I600 for the boost and then a CTI J94 sustainer. It sims to about 30,000. I have been gathering/repairing/making/prepping for all of the last 2 days and now I have had successful ground tests on my second try. Posting here for future reference on the charge sizing.
First the apogee charge of 0.34g in my nosecone ejector:
Then 0.34g in a plugged cardboard tube for the main ejection:
I’m reducing the main chute charge to 0.30 grams and keeping the nosecone at 0.34
(I’ll edit these later since the videos don’t seem to be loading from my phone)
