<DIV>George, Del,</DIV>
<DIV> </DIV>
<DIV>There is no evidence to support that the LiPoly batteries,
motors and/or ESC's will last 1000 cycles/flights. There is ample evidence
in favor of these systems failing at less than 100 cycles. I have heard from
several who have run electrics in patern models, and they all have had some
issues with any of the three items.</DIV>
<DIV> </DIV>
<DIV>Be that as it may, the electrics are here to stay and, to me at least,
are a welcome addition to the choices we have in powering our beloved
pattern models. I am still not ready to commit the money to outfit a pattern
model but am getting closer. </DIV>
<DIV> </DIV>
<DIV>I have committed time and effort in developing a new landing gear
design to accomodate electric set-ups. All features will be the same as the
present gear design I offer, except longer struts for the larger props. I want
to ask the folks who are into electric power for feedback on what kind
of gear design they are fond of: straight out from fuse center line, or raked
back with straight legs. </DIV>
<DIV> </DIV>
<DIV>TIA</DIV>

Yes all you points about the advantages of electrics are real George.
<BR>But I for one would not choose to keep both glow and electric in my
hanger. <BR>The logistics of such an undertaking is to much for me
personally.<BR> For some to claim that electric isn't going to
change pattern is <BR>foolish.. Just look at the maneuvers that are created
for new schedules that <BR>dictate you must get a comparable competitive
aircraft if you are going to <BR>fly in that class. How many are allowed
to move back because of inadequate <BR>equipment?<BR> I will get
off my soapbox for now. I am only asking for the rest of the <BR>answers to
real questions that to me appear to either being ignored by those <BR>in the
know or it paints a big black eye for electrics and they don't want <BR>to
show the ugly side of it.<BR><BR>

<BR>electric!....................................................YET!!!!!!!!!!!!!!!!!!!!!!!!!!!<BR>
However, and it's a very big HOWEVER, I keep hearing about how
<BR>unbelievably expensive it is to participate in this aspect of the hobby. I
<BR>don't know that I can concur with this conclusion.<BR> I think most
of us lower eschelon participants are probably paying <BR>approximately $15
per gallon for fuel and the guys that are burning 30% heli <BR>somewhat
higher. Now, using the lower figure and running a 16 oz tank I'm
<BR><BR>getting about 8 flights out of every gallon I purchase(how many of you
guys <BR>are running 20 ouncers?) To me that approximates roughly $2 per
flight. All <BR>of the sources that I have been able to query indicate that
the current crop <BR>of lithium technology paks should cycle in the 1000 cycle
area if properly <BR>charged and discharged(no over-charging & no deep
discharging) which is <BR>easily achievable with currently available
programable ESC's.<BR> Now even if you figure on a pak like Jay is
running where each half pak <BR>costs $350(total $700), the 1000 cycle cost
comes out to .70 cents per <BR>flight. If you take it one step further and
consider a smaller size <BR>airplane, the cost per flight goes down
substantially as some of the local <BR>guys, in my area, are getting 3 ten
minute flights per charge.<BR> I don't know about you, but in my book,
the numbers are pretty compelling, <BR>rivaling the price that I used to pay
for my 60 size ignition powered Super <BR>Cyclone on Amoco gas.<BR>
Additionally, I have yet to see an electric motor advertized for $700 like
<BR>some of our glow motors.I think if I was Mr.Yamada I would have a little
bit <BR>of an uneasy feeling in the pit of my stomach regarding the future. I
think <BR>the writing on the wall is either pulsating or glowing 'cause it has
<BR>electrons behind it!<BR> Just think,.......... no glow plugs, no
glow fuel, no exhaust manifolds, <BR>no pipes, no starter, no starter motor
batteries, no fuel pumps, no tanks, <BR>no fuel tubing, no fuel dots, no fuel
line T's, no fuel line filters, no <BR>Cline regulators, no check valves, no
Mixture Carb servos, no soft mounts, <BR>no 7amp field box battery, no 409
clean-up solution, no paper towels, no <BR>igniter battery, no remote glow
receptacle and the list goes on and on. How <BR>much money did you just
save????? You may be able to retire earlier than you
<BR>anticipated!<BR> Nope!, I'm still not convinced that electric is
sooooo- expensive. I will <BR>acknowledge that if you are an individual that
burns 2 or 3 gallons a <BR>season, it's going to be a while before you start
to realize the <BR>differential.<BR> Georgie</FONT></BLOCKQUOTE></DIV>
