I've been foregoing the winter launches because the next rockets I have on my sked all have PETG fins (with carbon fiber or plywood cores), outer sleeves (over cardboard/paper tubing), and nosecones (foam filled).
I've shattered PETG fins before in a winter landing on ice. I've heard of other people avoiding Quantum tube in cold weather - but what about PETG? Does anyone have a sense of where it becomes notably more brittle than normal? 25F? 35F? 45F?
