What shelf life does glow-fuel have? I'm using Irvine Contest 10 that
I bought in April/May (Sandown show) and I can't get more than 1 or 2
degrees pitch at full throttle above the hovering pitch. e.g. 6 deg
hovering equates to about 7 degrees full throttle (idle up1) and
standard mode gives about 7deg hovering with 8 deg full pitch. I've
tried this with both a standard muffler and now with a Genesis Pro+
pipe. Any ideas?

Engine is OS32 SX-H on a Baron 30S, with Quick UK Glassies blades.

Thanks,
David.

Depends how it's stored.

Glo-fuel is hygroscopic, BTW, so it will absorb water vapour from the
atmosphere if you give it the chance.

I bought a load of fuel when the local hobby shop closed two or three
years ago, and have zero problems with it. Because it's stored sealed
and in a cool low-humidity environment, I expect to be able to continue
using it for a long time to come.

I have some out in my barn now for 2 years and it is still good. Bought a 55
gallon drum and tapped it all into 1 gallon jugs with very tight lids. That is
the clue.

I'm about to try a molecular sieve in some "wet" fuel. I'll report back in a
few days.

Sorry, off the subject a bit, (for anybody new to helis and other flying
objects!) don't EVER leave fuel in a tanks on a heli, or in a plane for any
length of time. I did this once, and the fuel causes the clunk to degrade,
and you get chunks of brass (clunk - this is not supposed to happen.....) in
your fuel. Your engine definately won't like it. If you leave fuel in a tank
with a clunk in it, (or anything brass), and it smells very bitter, (makes
your eyes water) get rid of it as it will ruin your engine!!!!!!

Some time ago several of us went together and bought a drum of fuel.  We had a
set up that allowed us to back fill (actually slightly pressurize) the drum with
argon while filling our fuel jugs.  Recently one of us got a couple of more
gallons of fuel from the drum and ran an OS .91 4 stroke on it.  No problems.
The person doing this checked the date on the drum;  1990.

You don't need to use argon -- fuel staleness isn't caused by any kind
of oxidation.  All you need is a *dry* gas.  You could probably use
dry compressed air with the same effect -- albeit an inert gas such as
argon does provide a tiny extra protection against a vapor fire within
the container and it is one of the cheapest gasses (next to nitrogen).

Okay now that we have that subject under wraps here is another question. The
last drum that I bought 2 years ago was 15%. I was wondering if any body knows
if Cool power 30% is available in a 55 gallon drum and where can someone get it
from?
