Yup!
While the knowledge of piloting full scale planes is nice, it's not even close to RC piloting,
much past theories and principles of heavier-than-air flight itself. Definitely get with
an instructor for those first few flights... until you see what it's all about. Things happen
a lot quicker with an RC plane, and you don't have the seat of the pants thing going on, either.

RC flying isn't hard, but there are a few gotcha's that the experienced guy will help you avoid,
and you might end up having the plane for more than a few joyous seconds of that first flight.
No shame in letting an instructor check it out first... then take it up and trim it all out, and let
you get your hands on it so you can see what it's all about... what kind of movement you need
on the sticks, its flight envelope, how to control it when it's coming toward you, etc... all that stuff.


Hey, you may be a natural, and solo on your first flight out... but that's awful rare


Edit... (because you had replied again before I got posted.)
Be careful with those "taxi tests" and don't let the bug bite you that has bitten hundreds or thousands!
It's so easy to get comfortable with taxiing, and think, "oh, just a little hop, then right back down."
That works sometimes, if you have the space... but more often than not, you either fumble it, or the
plane is badly out of trim, and you overcorrect a bad condition and make it worse, and the next thing
you know, you're staring at a pile of sticks wondering what went wrong. (must've been the radio... yeah!)
