Thanks Gig. I missed that page. The problem that I have with some of the
reporting is that there isn't much supportive data. To wit: Corrosion of
aircraft fuel systems. Specifically what systems and what are the
differences in auto that allow them to use the E-10 with apparent immunity?
I've heard that the gravity fed fuel systems don't seem to experience the
vapor locking and I've never experienced carb ice in any vehicle but my VW.
The CAT gage on my Lycoming never gets within a large margin of the yellow
zone and even in Canada along side the lakes with temps in all ranges from
20 F to 80 F have I ever encountered any hint of carb ice in my
installation. Now with the metal floats in the carburetors, I can't see how
alcohol would affect that. Some of the O rings in the gascolators and fuel
shut off valves might need changing. I fully expect to lose some power
using Supreme with 10% ethanol, but at price differentials exceeding $1.00/
gal?
I'm going to get some 10% Ethanol Supreme and put one of my A/C quality
fuel lines in it and let it soak.

Thanks again for the link. BTW are you going to Oshkosh this year? We will
be covering the helicopters down at the Ultralite runway again.

The biggest problem IMHO is that it holds water. All the other issues
such as it eating the rubber can be dealt with but you can't make
Ethanol not hold water.

As for OSH this year I don't know. Hopefully about that time I will be
finishing up the engine install on my 601XL and since I have waited a
while to get the engine (technically I still am waiting)I'm going to be
hard pressed to make myself break away from building to make it. But
Hell or high water I will be there in 2009 and will be spending quite a
bit of time down with the helos because I really want to build a Mosquito.

And speaking of the Mosquito. Will those floats on the UL version really
float the helo and would the deployable floats from say a Bell 206
qualify the Mosquito to still be flown as a UL?
