No, not really.  If you are worried about having enough power, I would suggest
popping for an Enya .09 Pet, or an OS .10 FP.

|2.  The plans mark the center-of-gravity but say nothing about how the weight of

|will I gain stability by raising or lowering the components in the fuselage?

Don't worry about it.  Install the radio for maximum convenience, and best
nose-to-tail balance.   Vertical balance makes little difference on a plane
like that.

|3.  For a beginner, how much movement should I allow in the elevator and rudder?
|The original design did not allow for ANY downward motion in the elevator.  I
|adjusted that to allow at least 1/4" drop.

Start with about 1/4 to 3/8 inch each way on the elevator, a tad bit more on the
rudder.  GET AN EXPERIENCED PILOT TO HELP YOU FLY IT.  

|Any advice on the installation of the radio components would be appreciated.  So
|far, so good.

Actually, I would suggest shelving that particular airplane for a couple of years,
and buying a 40-sized trainer and engine to learn on.  An 049 sized biplane is
not going to be terribly stable, will be very affected by wind, will seem very
fast (due to small size), and you really want to use a mini radio for it.  If you
started now, you could easily have a trainer done for spring.  Above all, though,
get an instructor to help you.  Talk to your local hobby shop about clubs, and
go to a meeting or two.  If you don't do this, you will be very likely to lose
your investment the first time you take it out to fly it.
