Kirkyboy -> Changing Fuels (8/6/2007 5:47:32 PM)
Hey guys, Have just finished my last bottle of Flair Yellow Spot which is 5% Nitro, 20% Castor and rest Methanol. Have just gone to model shop and bought Model Technics Formula Irvine. Which is 5% Nitro, 18% Oil (4% Castor and 14% "Klotz") and remainder methanol. From what I have found, my new fuel is a great general sport flying fuel. But it is now mainly synthetic oil, do I need to do anything before switching to this fuel? Cheers for any help Paul

What engine(s)?

Kirkyboy -> RE: Changing Fuels (8/6/2007 6:22:46 PM)
Irvine .46 Cheers

Just Engines indicates 18% total oil is fine for Irvine engines: http://www.justengines.unseen.org/fuels.htm Since you’ll now have 2% more methanol in the mix you’ll probably need to adjust the needles some to compensate.

Kirkyboy -> RE: Changing Fuels (8/6/2007 10:57:55 PM)
Yes, I expected that, but I don't need to do anything else then? I thought there was maybe some sort of procedure when switching from castor to synthetic. Cheers Paul

There aren't any procedures needed when switching (other than a retune of course) but personally I'd run a little richer with synthetics just to be on the safe side.

carrellh -> RE: Changing Fuels (8/7/2007 6:14:40 PM)
There's no procedure that I know of other than tune and run.

Kirkyboy -> RE: Changing Fuels (8/7/2007 6:46:57 PM)
Thanks for your help guys. Think i'm going to run slightly rich for the first tankful just to be on safe side. Cheers people! Paul
