Is it better to build up the wooden body to convert it to electric
or buy the Fiberglass Monarch E body with the Chrysalis kit?
Which would be the lighter combo, do you give up strenght for
weight in the glass fuse? Will the built up wings fit the glass fuse?

Bill, the wing of the Chrysalis has more area than the Monarch, and the root
chord is also greater. The airfoils are also different, although the wing
saddle design on the Monarch 'E' could accomodate that. Because of the chord
difference, though, it would be very difficult to fit the Chrysalis wing to
that fuselage.
A bigger problem area is the tail. The greater area and mean aerodynamic
chord of the Chrysalis wing means the tail design is quite a bit different,
both in areas and in moment arms. This would require quite a bit of
aerodynamic redesign and experimental tuning. The balance between static and
dynamic stability would also be permanently altered. It may be possible to
end up with an acceptable model after a lot of work and testing, but you're
looking at a lot of work and risk.
Assuming you went ahead with altering the 'E' fuselage, the larger tail
required would change the loads on the tailboom, which might open a whole new
can of worms!
I think you've probably already figured out my recommendation, the 'E' and
the Chrysalis are both good models, but mixing and matching parts from each
is risky. I think your best bet is to alter the wood fuselage that comes with
the Chrysalis kit. The glass fuselage from the 'E' would be lighter, but it
is not suited to the Chrysalis wing. It would be better to build the wood
fuselage, fly a lot, have some fun, and save your money to buy an electric
version of the Monarch 'D' or Wizard ( the 'E' fuselage is available with
either of those wing and tail combinations) when you're ready.
