Welcome M. Michael Meyer... There's never a dumb question!!, It's only dumb
if you do not ask it:-)

On the Battery, I use the "pull" type wire ties, I usually find a spot that I can
attach or drill a small hole in one of the inner struts to attach the tie too.. But
if the spot that you are going to put the battery and/or reciever is tight enough,
wrapping both in extra foam for a tight fit will work also, That's the way I install
my recievers to date, Most my batteries are wired tied, and one with just foam in
a tight spot.... I guess your manual is where your getting this info... But after
the plane is all setup and with an empty tank when you check your C.G.(it's
in your manual) you can move the battery/reciever to get the C. G. right on...
Velcro will work also, aslong as you have enough to support the weight and
movement of the plane... I used it on my first plane(Avistar)...

On the charge plug... Most radios come with just an on/off switch, with the
charge plug... You can do as you said and remove the wing to charge( A fully
charged battery will last longer that three flights, But you should always check
it after the thrid flight).... So you could just make a hole in the fuse to have the
wire hanging out( not real nice) Or have it hanging out before you attach the
wing(still not nice, but works, tho you could wear the wire bare) Or you can
buy another switch with the chargeing plug adapter build into the switch...
Which for me is the best and best looking choice... Hope this helps!!

Well Be safe, Always check your plane before starting it:-) And Have fun in this
Great Hobby!!!
