I was flying my Raptor 50 yesterday and it was about 39 degrees. The helicopter started fine with no issues like always, but 3 min into some pretty hard 3D flight it just shut off so I auto it in and check everything over start it up again and take it back up. THen again it shut off on me for no reason in about the same amount of time. Could this be a glow plug issue even though it starts fine? Is there a better plug to run in cold weather? A hotter plug? (Enya 8 Vs os 8) or do I need to lean out the motor? This is the first time I ever had a flame out so I don't know what to look for. Any info would be great. Oh and I am using 30% Cool power.

When you are flying in colder weather, the air is more dense and thus carries more oxygen. This makes your mixture a little lean. Richen it up a few clicks and it should solve your problem

I agree with Peter, likely heating up on you. Or....

Did you refill before second flight? If so, then maybe look for a break in fuel line inside tank?

Flame out

I just got back from the park and Peter you were right I went out 3 clicks and it seemed to be fine. This is really my first time flying in cold weather (well 35 and below that is) I have never flown this late into December but I've had the bug lately. So now I know to just richen it up a bit and I am good to go. Thanks for everyones responses, and have a merry Christmas!

You also want to check the belt - the boom will shrink causing the belt to get too loose

also, check to make sure that the fuel line in the tank has not folded over and pinched off. This has happened to me. Check header tank too. Amen on the tail boom shrinking.

Belt shrinking

Yes I am aware of the belt shrinking in the cold weather, it gets tighter not looser when it shrinks. I made the adjustment to it at the field.

The BOOM will shrink more than the belt causing the belt to become loose. Trust me,I live in the frozen North.....
