This question is intended for part of the world who have below freezing point 
WX. I have an elevation rotor the Yeasu G-550 installed up side down but who 
work 2 winters seasons here. This year he just start to freeze and he stuck 
under minus 0C temperature?

Just before having to dismantle about 6 beams on the boom did anyone 
experienced this problem? As it seems this rotor has no draining holes i just 
think to add one to let the excess humidity to get out of the casing hoping the 
next above freezing point period will melt the ice build-up allowing water to 
drain out of the rotor casing.

Thank's for your input before i start drilling in the case...:)
