I fly as much as possible and even in winter - If I can get a clear calmish day ... temps can be down to -20C at times ... last winter we hit -35C one night.

I keep spare LiPo in pocket to stay warm ...

One day - vid is on Youtube ... the 450 Heli would barely lift and stayed just a few cms of the ground ... showing that extreme cold did make a difference. The Lipo ... a 2280mAh 3S 30C good condition pack just couldn't work enough to generate heat and warm itself up ...

I have been thinking about pocket warmers as sold by Camping / Trekking shops .... maybe a PW fitted into a box could keep LiPo's ready for use ?

Anyway - flight times as original post was talking about ... I think if you fly to 45% or so on a LiPo as normal - then that's good enough in winter as well as long as temp is not extreme as I tried ... then to be honest - you can forget it as hands / fingers fail before the model !
