It all depends on your interest and what type of

aircrafts. This article addresses the characteristics of flying electric
jets and some suggestions for suitable power plants.

Static Thrust Calculator Ever wanted to know how much
thrust your engines giving ?
Some may find that foam planes are easier to
build and quicker to assemble. With all the new materials available this is
possible. I'm not an expert in this field, but have learned some
valuable trick. Now a complete airplane can be created from these materials.
What I like the best is the resiliency (invincibility) of the craft. How
often can you crash a plane and make quick repairs and fly again? With
basal build-up this is not often possible. When I go to a flying field I
would like to put in as many flights as possible, and this is only achieved
with my foam planes.
A good source for ready made tools is Feather/cut and Compufoil,
The Compufoil is a good source of airfoils. You can also buy additional
airfoils. It can also help you with your wing designs. There is also a
tutorial on how to cut foam, making templates, and
is THE place to find out anything you could
want to know about BlueCor, Fan-Fold, Foam-Core, Depron, you-name-it foam,
for building radio-control aircraft. This material is not available in
CANADA, however you can order it with a link provide by this site.
This type of construction is unique and resilient to being damaged with a
great potential for new designs.
The Ductling II is
built from DEPRON, interesting results and findings.
DEPRON now becoming a favorite with building model planes because of
it's unique properties, however it is not readily available in North
America, it has to be imported.
Foam cutter details

I have encounter an
individual with the same interest in building processes and discovered a new
source of materials readily from a most unlikely source, yet common and
similar hobby. "Rocketry" The nose cones of rockets are a
perfect example. I will let you think of the possibilities you could use
found in the pass a valuable lesson to treat your batteries with care.
Not to overcharge them, for
this will over heat them and possibly explode.
For Nickle-Cadium let them run the full duration
of the charge. (discharge them completely before recharging) This will
reduce the possibility of forming a memory allowance.
You may want to log your
flight durations, to have a benchmark of your battery performance. This
will help with maintenance.
If battery pack is showing
signs of decreasing duration. This may be caused by poor charging habits
or bad cells. A recycling process is can determine if it is memory
allowance problem. If not then a bad cell is the cause.
Consider a good investment in
purchasing a digital charger with dual power source AC/DC,
charge/discharge, multiple battery pack configurations, fast/slow
charging, and most of all indestructible and reliable....

HOW TO BUILD A BRUSHLESS ELECTRIC MOTOR

A Brushless Motor You Can Build
With all the new RF towers
sprouting up around us you may want to consider this option for protection.
A solution to minimizing motors
generated radio noise in smaller planes with tight fuselage compartments is
to ensure the electronic speed control (ESC) is located away from your
receiver as far apart from each other and that all wire leads are twisted
(braided) to help with isolating the radio frequencies. This some time
is all that is required to do.
Motors generate radio noise
which can interfere with your receiver and cause problems. A solution is to
filter the noise by using capacitors and a Schottky diode. Two .10uF (104)
and one .047uF (473) non-polarized, ceramic capacitors. These capacitors
should be used at all times, and on every motor to help reduce the radio
noise generated by the motor and prevent possible damage to your electronic
speed control (ESC).
The Schottky diode will provide a slight increase in the ESC efficiency and
reduce its operating temperature. The Schottky diode must be installed
correctly. Installing it backward will destroy it.
Correct installation of the
