time. Do your final fitting with your choice
of spacer between the fuse and spinner. A
plywood ring just smaller than the front of
the fuselage works best. The front of the
fuse has the proper right and downthrust
molded into it. A 1/16" space is all that is
needed with an electric motor. Once you are
satisfied that the firewall is properly fitted
and not causing any bulging to the fuse sides
you can glue it in with 30 min epoxy mixed
with micro balloons. Tape the spinner to the
fuse to hold the firewall in alignment while
the glue sets. After it hardens remove the
motor and fill in any gaps between the fuse
and the firewall and add small epoxy - micro
balloon fillets.
The precut openings in the firewall can be
opened a little bit further to reduce weight
without sacrificing strength. The firewall
started at 41 gms and finished at 34 gms
ready to install.
Electronics installation:
The speed controller can be mounted to the
side of the front of the fuse, the floor in front
of the battery packs or the back of the
firewall if you need the weight moved as far
forward as possible. Just make sure that it
stays cool enough on your first flights.
Reposition for better airflow over it if
needed.
Additional electronics, your receiver, battery
pack and regulator can be mounted to the
sides of the fuse with Velcro. A small 2 cell
lithium poly battery pack and regulator
weigh less than a standard 4 or 5 cell air-
borne pack. They can also be mounted just
behind the gear supports on the panel that
makes up the rear wall of the chin cowl
cutout.

Air outlet:
There is no air outlet from the fuse so ex-
haust holes have to be cut. Any design or
pattern will do as long as they are large
enough. The Valiant has a nice ridge molded
in the bottom of the fuse that adds additional
