The YS stuff runs, and runs great. However, it is definitely a different setup than you are used to. The 1.10 is a pressurized fuel system and that has its own specifics that are a little different. For the Venus II, there isn't any advantage to have the 1.10 over the 1.20AX. The fuel system is nice, but not really necessary for where you are at the moment. You are familiar with the 2 strokes, and they run great. The 1.20AX is no exception. The YS stuff just is different. Not better, or worse, just different. I personally LOVE the YS stuff in the higher classes, and wouldn't trade my DZ's for anything. My 1.10 is great as well, but there is definitely a steeper learning curve with the pressurized systems than the OS 2 strokes. Fuel consumption is also higher with the 1.10 and you'll get better performance with high nitro's, which isn't really necessary with the OS. 15% Nitro, fuel, flip and fly which is much more benficial to you financial and for peace of mind right now,
