As do most Phoenix Model kits, the Genesis includes the necessary
pieces to use either nitro or electric power.
with an instrument panel and pilot seat. Removing the hatch
exposes the interior of the fuselage, making installation and
access to the radio gear and flight battery/fuel tank easy.
The included 15-page assembly manual features sketch-style
Phoenix recommends either a RimFire .46- or .55-size
brushless outrunner motor when choosing the electric power
system. Parts required for either nitro or electric power are
Electric power requires a small plywood subfirewall to be
mounted to the main firewall to create the proper motor
standoff and spacing. I chose the RimFire . 55, because of its
slightly higher net power rating and specified ability to swing
larger propellers. After all, the full-scale Nemesis was famous
for flying fast! However, the differences between the two
motors are subtle at best. With identical dimensions, either
motor will fit.
Before installing the mechanical retracts, I used a sharp
hobby knife blade to remove the Oracover covering from the
underside of the fuselage and wings. The main gear retract bays
are a thin gauge, Lexan-style plastic that must be trimmed to
the required size before installation.
Assembling the Genesis may require tools not normally
used when assembling an ARF. Curved-tip scissors work best
for trimming out the gear bays. I initially rough trimmed them
until they would start to slip into the openings in the bottom
of the fuselage, making the necessary small clearance cuts last.
I anchored these plastic main gear wells in place with white,
canopy-style glue. When the glue dried, I applied a second
round of it from the topside, working through the cavernous
canopy hatch opening to apply additional glue where the
plastic contacts the wood fuselage and formers.
The plastic gear bays are prepainted blue to match the
fuselage, but after they were installed, the cut edges were
glaring white. I used a blue Sharpie to blend them back into
the blue covering.
Each mechanical retract has its own quality Futaba retract
servo. Mechanical setup is much easier than when using one
servo to drive two retracts. After retracts were installed, I
noticed that when retracted, the geometry between the two
was different. Closer examination revealed that the hardwood
mounting blocks embedded in one wing half were slightly
canted. Remedying this was as easy as shimming the low end
of the mechanical retract with a couple of flat washers.
The short, stubby wing halves are removable. A thick
aluminum spar protrudes from the wing root and serves to
anchor them to the fuselage. A small gap remained between
the wing root and fuselage after I had them fixed firmly in
place. The end of the aluminum spar features an open slot
design; the thick aluminum spar is pinched under a cap screw
and flat washer that holds the wings in place.
