Hi guys,
I have got a problem with my 250 while flying in cold weather... The rotorhead gets stiff and paddles are very hard to move... this causes very sluggish controls and the heli is very hard to control and after a new input she doesn't come out of the previous one... I have lubricated the parts with WD-40, could that cause the problems I am having? And if how to get it out of the parts and what to use as a better lubrication?

Thanks

Airkid

No lubrication and you will have to re-size your ball links, the ball links gets tight in the cold compared to the inside of your home. You may still have problems because of the lube in the bearings, It's freezing were your at.

I keep my links dry and lubricate them with dry powdered graphite. I don't think you will ever get the WD40 out of the old links.
