Ill be using electronic single deploy for the first time this weekend (with motor deploy backup) at MMMSC, which Ive also never been to before. I live in the city in MA, so storing BP legally isnt possible IIUC given the layout of my home, and even if I was willing to play loose with the storage rules (Im not), ground testing in my backyard would be a *terrible* idea - 100% chance police would be called. The club has told me I can buy/borrow BP and do ground testing at the site on launch day, but Id rather not spend all morning on it, so any tips on ground testing at site with a minimum of fuss and busy work? I have a 4 fiberglass airframe with a slightly unconventional interior that works out to about 200 cubic inches of volume to be pressurized with the motor Ill be flying. My reading online suggests this may need about 1.5g of BP, so I may just start with that and if it looks good go with it.
Alternatively, since this is a kit (Madcow Little John) that is designed for motor deploy only, I could just load the altimeter-controlled charge up with 1g of BP and launch and rely on the motor charge for if the altimeter charge isnt enough. That would solve the not-spend-entire-launch-day-groundtesting problem though Ive heard that if a charge isnt enough to separate a rocket you tend to really really cook the laundry
