BigA1982,
I'm not familiar with a Yuki or FMS nor have I seen any at the field but I've built and flown a Sig Riser and a Gentle Lady, both 2m and excellent flyers and a great first glider, the Gentle Lady is available as a ARF as well. I bought a foam Parkzone Radian ARF for $160, it includes a 480-size 960Kv brushless outrunner motor, 30A brushless ESC, and servos, all installed. I had it built by the time my battery was charged, it's also easy to fly and is great to learn to thermal with. I can easily put 6 flights per battery charge because it gets to 400' so quickly.
There are lots of threads about Radian mods out there. Even though the stock motor/prop combo works really well I plan on replacing the prop, spinner, and motor soon. My two cents any ways.
