I fixed the wing on my Big Stik and made a new fuel mix:

4 parts my Black Brew + 1 part Davis plane.

I flew this for 3 hours of flying time today. It worked well. It will start without the plumbers torch. Hand starts can be done but it is difficult. It needs alot of choking till it gets warmed up. The air temprature was in the high 50's. Well see how it works when the temps are in the low 50's and high 40'- it dosen't get much colder here anyway.

A rough caculation says this is about 5 to 6% either if Davis fuel is 30%.

This mix will cost about $9.20 per gallon which is still pretty good considering I get 3 minuets of flying per OZ. My K&B .65 is more thirsty but it still alot cheaper than glow fuel.

I can still go to Kerosene insted of pump diesel if I have any more problems.

By the way my used oil is RPM Dello 400 15-40 Chevron Diesel oil. I don't think additives hurt at all an if anything they might help. My used oil is pretty clean ( although black ). In my Cummins it goes through the full flow filter thousands and thousands of times and is still good oil when I drain it. I have a powerfull magnet on my drain plug and there is no trace of metal on it. This is the only vehicle that I've ever owned that doesn't have some metal on the magnetic drain plug at oil change time.


Andy,
another nice video! Do you do those with the a head camera?
I think it will be difficult to run eitherless in those kind of tempratures but I'm looking forward to hearing about how things work out.

Greg, I agree with you to a point about the vaporization. Our fuels needs to vaporize but I don't know if the crank case has to be above the fuel's boiling point but the fuel does need to be heated on the way to the combustion chamber. You may be right though.

Treven.
