RE: Parkzone P-51BL
as long as you don't leave snow residue on it, which later melts and wets down your electronics causing oxidation or shorts...i don't think it is a problem.
i belly land my eflite p40 300 in damp grass w/o adverse effects. i just wipe it down with a paper towel before loading in truck. i've flown my balsa/solite parkfliers in light mist w/o any problems.
