The stuff is great. I use the 15% in all my pylon racers and sport planes, and also use the 30% in my helis for 3D. I just broke in my YS .91SR for my Vibe with the 30% and the motor runs great. I have burned 5 gallons of 30% and have to say after I have compaired it to the rest it is as good if not better the the top name brand stuff that has been around for awhile. They will answer any questions you have right away and Stan comes to many of the contest for support.

Give Maxy's Fuel and shot and you will be hooked.
