If you do run it in that cool of temperatures, it may not run right when the temps do warm back up. I keep a winter and summer engine on hand for my trucks. My savage and mammoth will both probably be shelved for the winter since I don't feel like putting in a weak OS 21 RG just for snow. But, my revo will see some snow since I have the original 2.5R that still runs just fine. I ran the 18TM in the warmer months.
Although, I am thinking about getting a new era BB kit to install one of my extra OS 21RG's. But if I remember correctly, I had a harder time keeping the BB engines tuned last year than my SB engines. The smaller head/engine has less surface area so the temps stay more consistent. At least that's how it seemed.
