Fuel suggestion for cold weather?
So anybody got experience with running glow engines in below freezing temps?
I recently picked up some Powermaster 15% nitro with low viscosity full synthetic lube at 23%.
I tested it in my Great Planes Escapade 60 with an OS65LA in cool but not freezing temps sunday with good results. The oil left on the plane seems to be of normal thickness and the engine required only a small adjustment to fun fine on it. I noticed it transitioned from low speed very well, perhaps even better than usual.

I have seen the others in my club have trouble getting started in the winter, hopefully my new fuel choice and a good hot glow driver will be OK. Thanks.

It will help greatly if the fuel is warm, and if you have a hair dryer or heat gun to warm the engine a little. Those two things can make a huge difference.

I'm not a Jack fan, but I'd happily take a swig of Crown though.

I learned very early on.... If I borrow her fabric scissors (quilters have the sharpest scissors in the world I think) to cut fiberglass cloth without asking, holy cow. Bad news. She is quite protective of her $70 scissors. She gave me her old crappy hair dryer because she wanted a new one anyway... Now to get a crockpot out of her. Haha.

We have the Chili Fly on new years day, we all bring Chili or something and try to fly in below freezing weather with usually very high winds.
And personally I like Old Crow, I must be weird or cheap or something

Wild Turkey 101 warm all the way down I fly gas and electric so no problem getting started.

I forget now as to at what temperature the glow fuel starts to settle out the components, but it is usually way too cold for me at those temperatures anyway. I think it was someone up in Canada someplace who noticed it with the fuel. But I agree with the others in using a hair dryer to heat up the engine some and keeping the fuel warmer helps a lot. I used to use a transmitter mitten cover in the cold, that actually works pretty good, especially if there is some wind. I think they still make and sell the TX mitten covers, but they are easy enough to make though. If it is really cold, you may need to keep your batteries warm and put them in before you get ready to fly too.

It got down to +11*F the other night, and it just happened that I left my jug of fuel in the truck that is 20% all castor. It sounded "thick" but nothing settled out. If anyone can fly at that temp or colder, holy moly you're a dedicated modeler!

I like to hand prop my engines with a chicken stick. On cold mornings I remove the glow plug and place a few drops of fuel into the cylinder. Engine starts with a flip or two that way. This technique would make electric starting easier as well. It is important to keep the fuel warm, especially if it has a heavy dose of castor oil which makes the fuel more viscous and requires the needle valve to be richened in the cold..

I have flown in sub freezing weather quite a bit and don't recall having to change the mixture much if any from the fall setting. You don't want to be adjusting the needle in the cold or your fingers will be too cold to fly after you get it tuned. I usually use 10 - 15 % in my 46 engines and it works just fine. I do recall that it takes quite a prime to get it to kick over in the cold. Sometimes I think I have flooded it but it actually needed more fuel to start. You will find the lift in the cold weather is quite noticeable.
Oh, another thing is be very carefull of any plastic coverings. They get very brittle and will shatter if something drops on it. I even had my wing covering pop a hole it it from my finger hitting it too hard. If you wear glasses, be prepared to look around them if they fog up. Land before your fingers are too cold and become numb, your fingers become dumb when the get numb.
Below 0 deg F is about the limit for me. I have done it once and it is just too cold to even enjoy flying when it gets that cold. However on a very calm cold day, it is sometimes just too enticing to not go out for one quick round.
