exactly is your Edge 540? A Shock Flyer maybe? I love mine for the same
reason. I can fly at the local soccer field while people are playing and they
don't even know I'm there. Great for practicing rudder drills etc. If you're
flying a Schocky - what brushless / batteries are you
using?</SPAN></FONT></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">For a while, 90% of the focus
will be on batteries. A comparison could be made between a single
fluid pump drawing from three different tanks simultaneously--you will get a
slight difference in the amount drawn from each due to friction losses,
tubing or pipe characteristics, length, gravity, etc. If you put
the same amount back in all three each time you refill--eventually you will
get an under/overfill situation. Same thing happens with the cells(I
am surmising). In a heavy charge/discharge cycle, this is
dangerous. That's why cell balancing is so important as they tend to
get out of balance over time. This can be alleviated by individual
cell balancing every so often--if the pack is built to do so. Kind of
a large problem to my way of thinking as there are MANY packs out there that
do not have that capability....and no one is really talking about it.
Probably huge liability issues there.</SPAN></FONT></P></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The good news is several
manufacturers are working on individual cell balancing chargers with
multi-plugs that will do it all as they are charging at maximum rates.(Then
only one required.) One manufacturer thinks he'll have a 20c discharge
rate cell that will allow smaller, lighter packs with
possibly higher charging rates. We'll see. Another has gotten over 700
cycles out of the pack and apparently still over the arbitrary 85% cap.

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Several folks are working on new
motors--direct and geared along with some large programmable controllers.
Apparently, most of the problems have been centered on too much draw (too
much prop) that screws up the motor magnets--causes The motor to
draw more than the controller is rated for and blows the controller if it
hadn't already been blown. Evidently if you use the stuff as
rated--the systems are fairly reliable.</SPAN></FONT></P></DIV>

take the jump--I have built several small park and indoor airplanes.
It's pretty nice to run down to the park at halftime and get in a couple
flights and only miss a few minutes of the second half. The power is
there and can be controlled well. It DOES feel a little like
cheating! The manufacturers are working on ways to get the weight AND
the danger out of the batteries.</SPAN></FONT></P></DIV>

the systems are operated within capacities and balanced properly they will
last FAR longer than 100 cycles. I suspect that once you do it by the
