And for Glow-Fuelers, like me, The OS 1.20 works just "Peachy". Only a few flights because of the strange weather here but, it's really a smooth flyer, just like the GP Super Stearman. They pretty much go hand in hand together. Both are very relaxing and enjoyable to fly. Just wish the winds would stop, it's howling at least 30 to 40 MPH gusts outside. What in the heck is going on ?. MM
