The Glow fuel will eat the hell out of it. I did give it some thought, but not about to take a $135 risk. I think later today I may take the 125 out back and give it a tuneup. I did some adjustments to the landing gear on the Mustang, and replaced the 14 ounce tank with a 16 ounce one that I can see the fuel in. Once I can get the 125 to run as good as the 100, and now that the wheels roll freely on the Mustang, it should be much more enjoyable to fly.
