Just wondering why would you change fuel % in winter?

(I run) lower nitro in the winter because with the more dense air there is more oxygen.
Able to lean out the motor for longer flight times while still maintaining adequate power.

I'd try some 0% if I could find some.

At 20 deg f outside and 10% nitro, 2500hs, it make more than enough power for my ugly flips,rolls,& tictocs.
The motor on this thing is a monster, I'm used to flying the raptor with the same motor on 15%

Sorry thats wrong, you need to run richer in the winter... more dense air = more fuel needed to keep the same mixture ratio.
60% of the time, it works every time!

I run 30% in summer and 20% when colder. Same power and longer flight times. The dense air really allows the blades to bite, making the Heli really come to life!Enjoy things that money can buy IF you don't lose the things money can't buy.
