use the jr 821 servo for the rudder. It's high torque digital, about 39 bucks or so. That way you stick with all JR. If the elevator seems sluggish when you fly it, switch out those servo's too. The aileron should be ok.

I take it you've flown before, have you flown a pattern type plane before? If not, take it high and practice with it until you get the idea that they are somewhat different from other planes, that they fly where you point them. They fly nice and smooth and that's good.

I would upgrade it to one of the new OS 55's to give you more vertical. Other than that, you made a pretty good deal there.
