Yea I read that so it saves some time for sure. I think a day or two and I could have it flying. My biggest problem is I can't afford to buy a bigger motor to go in it so I have 2 options. I go with the OS 120 and see how it flies or put the Ryobi in it, but I don't want to ruin the look by cutting the cowl and have the big engine head sticking out. I do have a saito 150 but it is currently in my PT 17 Stearman which is way over powered. I could swap motors and put the OS 120 in the stearman and put the 150 in the Cub but that would be a pain. I would love to have a Evolution 26GT2 to put in it, its small enough so I don't think much of the engine would stick out unlike the ryobi which has a big cylinder head. I have the great planes 60 size cub in the clipped wing version 83" and the full wing is 90" and it flies great with an old tired thunder tiger 91 fourstroke. Thats not that much smaller than this so I bet the OS 120 would fly it fine.
