G80T motor dimensions ASAP

Anyone with a spent G80T and calipers handy? Need nozzle geometry for CAD

Can't find nozzle-end dimensions anywhere — does it protrude past the casing, how much, and what's the OD? Even a photo next to a ruler would be a huge help. Thanks!

Rocket motor problem

Hello, I am planning to make a rocket that uses active control to stabilize itself. For this I need to have expensive electronics on board and have to use a manual parachute ejection charge. Which motor that is preferably high class (f-g) and long burning should I get so that the motor itself doesn’t have an ejection charge that ruins the electronics? Please be specific and if you can give links.
