RE: Parkzone P-51BL
You'll probably scoop up some snow through the air intake on the bottom front of the cowl. Just make sure you get it out before it melts and gets your motor wet.
If you've not flown this plane before, it lands on a skid on the fake super-charger intake on the belly and then immediately tilts forward so the front of the cowl and air intake scrape along the ground. I typically get a little dirt and grass in there and have to shake it out every so often. Landing in snow, you're sure to get a little snow in there, but if you clean most of it out of there you should be fine.
