Seems that the oil % is the same in both as is the type of oil. What is the difference and has any body ever ran the plane fuel in a heli??? How did it do???

There is no such thing as up, it's all out...

It's the same fuel or at least it used to be.

I use the 2 and 4 cycle 15% wildcat.

I called around to some hobby shops in other states just to see what the prices were, one actually told me that they did not have any in stock and didn't keep much because most everybody was going electric. Not sure that weighed and measures out!

A few years ago i found the same thing with 15% Cool Power, even called Cool Power and they agreed it was the same formula for plane and heli fuel but yet they charged $1.00 / gal. more for the heli fuel back then. Not sure where the prices are now.

Just keep an eye on the oil content
at least 18% or better castor/synthetic blend best

you could run 10% airplane fuel but it would not be as fun as 15% heli

spending time, paying attention

If you want the answer straight from the horses mouth you can call Wildcat directly or PM Jerry right here on RR.

I've always used heli fuel in my planks, but never plank fuel in my helis.

See Jerry's RR ID in this thread:

Call Jerry. I think he's going to tell you it is NOT the same. The oil package is different. It may be the same amount of oil but it is likely a different viscosity. I can tell you from experience that they tune slightly differently which suggests to me they are not the same.

Ok thanks for the info, I think I will just use what specific type is for each.

If you are going to run lean enough to burn a hole in the top of the piston, then you should get the heli specific just in case it is slightly different. Otherwise, if you lumber around slightly rich, it won't matter and availability is the most important thing.

If I was standardizing on one or the other, I'd go with the Helimix since it seems to me the heli engine is a more demanding application. I have used 15% Helimix in smaller sport airplane engines but the airplane engines that really matter to me gets 15% Wildcat Premium Extra.

Just watch for the oil content and stay away from castor oil.

In general the oil content in Heli fuel is higher.
