ok on two stroke's carb in front i run airfilter's. my plane's are a little overpowered so the will make their own runway. snow is very easy to go thrue . i have taken off in grass about 14 inch's tall. so snow don't bother me much. i fly all my plane's but my propjet's in snow. 1/4 scale's are better to fly in snow than a 40 size. but ski's work good to. the most snow we get here is about 10 to 15 inch's normail but we have got 37 inche's
