Dave...
I need to pick up some fuel tomorrow..

I have been using Powermaster YS 20/20 and want to try some 30% heli...

One store has Cool-Master 30% heli
the other store has Power-Master 30% heli.

I'm sure either will suffice...but if YOU HAD TO CHOOSE BETWEEN THEM....which would you Prefer?

Thanks

Larry

Either is fine. The Coolpower is probably more widely used, but we use the Powermaster in our shop and are pleased with it's performance.

I ran my first few tanks of the 30% Heli...Coolmaster.

WOW..It's like an entirely different engine now!

It's like it was designed for that Nitro content!

From now on..It's all I'll ever Use in that 110.

Any negatives to using it 100% of the time?? (Besides the Price?)

Larry

The only abuse will occur in the wallet! We have LOTS of our customers who use 30% (and higher) amounts of nitro with good success. As long as you don't get it too lean, the engine will handle it just fine.
