Hi,
I was in exactly the same place a few years back as mrc100, his comments are spot on.
All i would add is you should be able to handle the plane, its more down to how its setup.
When i test flew my Cap 232 for the first time the controls were set soft and the CoG slightly forward just to make sure i would be ok. As it turns out the model flew like a trainer, then i bumped up the rates and moved the CoG back once i was comfortable...this was done gradualy to make sure everything would be controllable.
I would also suggest having someone with some knowledge of the plane standing with you "just in case" or at least to offer advice if required.
Just my $0.2.
Good Luck and most importantly have fun!
