Need help with my first model

I bought my first RC plane two weeks ago and am having trouble due to a lack of
info in
the instructions. I have an electric Sopwith Pup from Kavan (foam not balsa).
The
instructions do not mention anything about mounting of the receiver nor speed
controller.
They show a small access door on the bottom for getting to the servos (just a
piece of
foam with a dowel stuck through it to hold it in place). There is nothing about
where or
how to run the wires. Here are my questions.
1. Where should I place the receiver and how should I mount it? (It's a Hitec
HFS-04mg).
How important is it for me to be able to get to the reciever plugs? If I mount
it under
the pilot, the servos will block access to it. Should I glue it to the fuselage?
2. The electric controller recommends placing it in airflow but the fuselage
doesn't
appear to have any holes. How big of holes do I need and how many in order to
create some
cooling?
3. I do not currently have an On/Off switch in the power cable. How important
is this?
I assumed that I would simply unplug the battery cable when I wanted the plane
off since I
would probably need to recharge it anyway. Should the battery connection be on
the
exterior of the plane (the instructions show the battery cable hanging out
through the
cowling) or the interior (under some hatch or cover)?
4. Should I tape the wiring down or is it ok if they hang free? I assume I
need to place
it so it doesn't interfere with the servos.
5 The instructions show mounting the servos with the control arms(?) pointing
away from
the center of the plane but my servos (Hitec HS-55) have control arms that stick
out both
direction from the pivot point. This prevents me from mounting the servos close
enough
together to fit in the fuselage. Is it ok for me to trim off the control arm on
one side
of each servo so they can fit closer together?
6. Where should I have the reciever antenna wire exit the plane? Is it ok to
have it
come out in the middle (behind the wheels) or should I have it come out the tail?
Thanks for your help.
