Setup
☐
Inspect the wings for any warps that may
have worked their way in when covering or
while the model was in storage, and remove
prior to flight. The
microMAX 103
is
designed to have a slight warp, or “washout”,
in each wing panel, as described in step 55.
This washout should be equal at both wing
tips, and should not exceed 1/4 in. Less is
ok, as long as both wings are equal.
Too
much washout will cause the model to
take on excessive amounts of trim for
level flight.
☐
Center the rudder, then set the direction, rate
of travel, and dampening (expo). The rudder
servo should be controlled by the aileron
channel of your radio, as rudder on this model
also controls the roll of the aircraft. Rudder
should follow aileron stick travel, i.e. moving
the aileron stick to the
right
should move the
rudder to the
right
of the aircraft.
☐
The elevator will be controlled by the elevator
channel of your radio. Moving the elevator
stick
back
should move the elevator
up
,
moving it
forward
should move the elevator
down
.
Our
microMAX 103
was designed to be a
very draggy, docile flyer, therefore the flight
controls are set up for fairly minimal throws.
With the pushrods connected per the
instructions in this Assembly Manual, the the
control throws should be as follows:
Rudder Travel
Rate +/- 20 degrees
Elevator Travel
Rate +/- 15 degrees
Pre-Flight
Have an experienced pilot assist you with pre-
flighting your new model. Just like having
someone proof read something you’ve written,
having a second
fresh
set of eyes to inspect your
final product is often helpful at avoiding disaster.
While not an exhaustive pre-flight check these are
some of the major items that you should consider
using when developing your own pre-flight check
list. Get in the habit of always pre-flighting your
models before each and every flight.
☐
W e i g h t a n d B a l a n c e
- C h e c k t h e
microMAX’s
balance. The model should
balance on the mark etched to the bottom of
the
right
and
left
wing tips.
☐
Use your
right
and
left
hand index fingers and
suspend the model from below, at the marked
balance point. Now, site from profile of
aircraft against horizon. If the
upper edge
of
the fuselage side and horizontal stabilizer
appear to hang level with horizon line, then
the
microMAX 103
is properly balanced to fly.
Move the battery within fuselage, and/or add
clay ballast to the nose or tail to obtain proper
balance.
☐
Check Weather
- The
microMAX‘s
first flight
should be outdoors and in
zero
wind
conditions. The
microMAX 103
is capable of
flying in winds up to 10 mph so long as the
pilot is capable.
☐
Inspect airframe
for warps and obvious signs
of wear or damage. Do not fly a damaged or
warped model.
☐
Inspect control surfaces
for center, proper
direction of travel, rate of throw, secure
pushrod connections, hinges, and receiver/
servo mounting hardware.
☐
Check wing attach points
for damage and/
or wear and that the wing struts are properly
attached.
☐
Inspect battery for full charge.
Never begin
a flight with a partially charged battery.
☐
Clear prop!
Stay clear of the prop arc when
the model is powered. Sure it’s a little bitty
flexible plastic prop but it’s still fun to yell
“Clear Prop” Before applying power to the
model... and an excellent habit to form.
