The pieces were well packed and arrived undamaged in a remarkably small box.
The fronts of the nacelles are held in place with locator pegs
and magnets and are easily removed to access the motor
Reminding you to thoroughly read the instruction manual
before beginning assembly seems unnecessary, but I’ll do it
anyway. Do yourself another favor and download the full-color online manual. The included manual is fine, but color
pictures help make the details easier to figure out. Maxford
recommends following all of the steps in the manual in order
when completing the assembly.
Assembly begins with the fuselage and setting the tail
control servos in place. This area is harder to reach later, so this
is a good time to place them. Use the EZ Link connectors to
attach the pushrods to the servo horns, but don’t tighten them
The motors and ESCs are mounted in the adjustable motor
mounts so they’ll be ready to install in the nacelles. This is
done early so the wire harness will be ready by the time you
reach that step in assembly.
After you’ve installed the motor mounts, it’s
back to the fuselage to fit the landing gear. This is
something that was changed between the time the
manual was printed and the kit was sent out. The
online manual didn’t yet reflect the change, but it
might by the time you read this. The manual shows
wheel collars and plain axles, but they are actually
threaded rods requiring nuts and washers.
Mine came with 3mm threaded axles and 4mm
nuts, so I made a quick trip to the hardware store
where I opted to get nylon locknuts. I like this
method of doing the axles and the rest went without
a hitch. (Editor’s note: Maxford USA now
includes nylon locknuts with the Gotha.)
The manual clearly shows which length leg
to use where, so pay attention as you go. They
only fit in the fuselage one way.
The tail assembly is next and there is
nothing unusual there. If you’ve assembled a
model before, this will be familiar. All of the
hinged surfaces require CA hinges that are
provided and the slots are precut. Control
horns are bolted through predrilled holes. Be
sure to put the horn on the Z-bend of the
pushrod before bolting it to the surface.
The lower center of the wing section is
an important step. The prewired harness is
already installed, but you need to mark the
servo ends now to avoid confusion later. Using
a servo tester or hooking up some servos and
a receiver works well.
This section is mounted with wing
dowels in the front and bolts in the back.
Everything is predrilled and the blind nuts are
preinstalled in the fuselage plate. The shorter
of the two carbon-fiber wing rods is for the
lower wing section. The nacelles are mounted onto the rods
and glued to the lower center section.
There are three things to be aware of on this step:
1. Look at the manual and drill/mount the rigging swivels
in place before attaching the nacelles. They will be difficult to
reach with a screwdriver or drill later.
2. Feed the wires carefully into the nacelles. I hope you
removed the covering before joining them. You did read the
3. The screw heads for the landing gear legs will fit into
corresponding holes in the wing panel edges, allowing for a flush
fit. Make sure that they fit perfectly! A couple of mine required
slight enlarging. This is not a big issue if you catch it now.
The upper center wing section is next and requires
