Electric NexStar Tips
These are only suggestions
and may or may not work for you!
Like everything in life, there are no guarantees!

Always
Stay Clear of an Electric Plane's propeller.
It's just like
a gun but they are worse!
Nobody thinks that an small electric motor can cut off a
finger WRONG!!!

When you
buy RTF park flyers, that include transmitters, those
radios
will not support "training or buddy boxes. This is
important
only because it's difficult for anyone to help. If you
are a
new flyer, consider spending a little more money upfront
and get "buddy box" compatible equipment. You'll be dollars
ahead! If you think I'm nuts, get on the beginners forums and
see how many times planes are destroyed or damaged.

When
setting up control surfaces and throws on a new
airplane? Take
off the Propeller!!! Save an Airplane!! |
Electric Motors & Props
|
|
It
is important to note that the electric motors mounts just
slightly higher than the OS 46AX. The 12" prop has
the almost
the same ground clearance as its 11" cousin.
|
|
|
These
NexStars are powered by a TowerPro 3520-7 with a 14.2 volt
5000mah lipo battery and a 60 amp speed control.
We have also
use a "BEC" due to the number of full size
servos.
|
|
|
We've
found that a "K" series Master Air Screw 12X6 performs
very well with this electric motor. The MAS "K" series
was developed
for 4 stroke glo engines, that have a lot of
torque. Electric are very
similar to 4 strokes, so
these props work well.

Here's
a no-brainer! If you nose in your plane and bend
the
shaft DO NOT try to run the motor! Running a motor with a
bent shaft kills it! After the hard landing check for a
free
turning motor, otherwise replace the shaft first!! |
ESC's & Servos
|
|
Here's
some great information about esc's. Click on the
underlined link.
|
|
|
Servo
buzz is generally not a big deal, but it sometimes can be
eliminated by making sure that the servo is at the "neutral"
position when at rest. Do this by centering the trims,
install the servo arm so it is a right angle to the servo case
and then adjust the control surface to neutral by using the
clevis.
|
|
|
The
electronic speed control and battery in your equipment is
supposed to get warm, not so HOT you can't hold it. The
temperature is telling you something is not rated high enough
or
your prop is to large. The bottom line: you are drawing
to many
amps!
|
|
|
Figure out
a way to use your ESC (electronic speed
control) and BEC's
without adding an extension between the
battery and Esc.
The extra length sets up a "feed back"
problem that can
actually cause your esc to catch fire!
|
|
|
ESC
(electronic speed control) and BEC's. They can and do
emit RF that will (not may) interfere with your receiver. Keep
them 4" apart!
Especially the Polk receivers!!
|
|
|
ESC's
are rated for a certain number of servos. If that number
is exceeded the ESC will fail, leaving you in the air without
any
control of your aircraft. Use a separate BEC or
receiver battery
to power your servos. See the next item.
|
|
|
If
the manufacture does not specify the number of servos their
ESC/BEC will support then figure that one regular servo will
draw 1/2 amp. Therefore a ESC/BEC that has an output of 2
amps will support 4 regular servos. If you are using micro
servos, subtract one servo from the previous figure.
|
Batteries
|
|
Is
your lipo battery Hot (not warm)
after flying? There's only
one reason. Your lipo battery is
being discharged faster than its
rating. Check the motor
rating (max amps) and then check the
discharge rating on
your battery, it's measured in "C's". Multiply
this
number times your mah and the result should be equal to or
greater than your motor rating in amps. If it's not the battery
will destroy its self. |
Flying off Water
|
|
Flying off
water?
Seal the receiver with "Press &
Seal" plastic wrap. Make the
covering long enough so that you are able to twist tie the
servo wires on one end. The antenna wire can be run
straight out back end, be sure the wrap has been sealed
around the wire. Seal the speed control ends with liquid
tape. Just fill up the open ends and be sure to get around
each wire.
(Learned the hard way on this one!) |
