I'm in New York just north of Buffalo and I installed skiis on my Nexstar and flew the other day. 20 degrees "F" and lite snow falling. Took alittle extra to tune it in, would recommend a hot glow plug, but it flew great. THUMBS WERE NUMB, but it was a riot. Be prepared how easy the skiis slide on icy lite snow covered ground. Took alot of room to slow down on landing.
