I have used it for years in my planks, 2 YS120's and a YS140L. It works great in my OS32SX-H heli engine. I sold all my planks and fly strictly heli's right now and use only 30% in my YS80 and now my OS.32SX-H. I think I got 5 gallons in cans yet of 20/20 I need to sell of at the next club swap meet. It's a good all around fuel. 20% nitro 20% oil.
