i went from a trainer to a UCD .46 with a Saito .82 and it's fun...there really isn't anything to be scared of considering that you can limit the amount of throw either way with a programmable radio or from the horns on the control surfaces. I set mine up so that ail/rud/elev all had about 1" of movement either way. Once i flew the plane around 3-4 flights and got used to the plane a little and felt comfortable i moved everything up to full rates, there is a big difference at full rates but that can also be programmed out with expo if you feel you need too.

What i'm trying to say is don't be scared of these planes because you can adjust the throws before you fly it, besides it's nice having a plane to grow into instead of growing out of.
