Suitcase changed his old US 120 from a 3000 ST to a g-26. At first while the engine was new it was a dog but after more running time it has gotten stonger and stronger. Gas sure is cleaner and the engine is more reliable. A midair with a big tree has cased him to purchase a new US 120 Lite for his G-26. He is putting the servos in the tail and the fuel tank under the wing. Its not a hard mod to make and it sure is better than hauling extra lead just to balance. I can't wait to fly it. 2 1/2 lbs lighter with the same engine ,sounds like fun!
