<DIV><FONT face=Arial size=2>The street price for my FMA/Kokam packs will be
in the $400.00 range/set(I think), but they need a little more
capacity. Give it a little more time--there are becoming some
alternatives that will help pricing and reliability. Put these critters
in a light, clean airplane like an OMS with retracts and I'd bet you'd
have plenty. Icepoint?!</FONT></DIV>

<DIV><FONT face=Arial size=2>I also got the electric bug, but the battery
cost always seems to overcome my excitement. I used 8 gallons last year and
havent' got through my first gallon yet this year. Though I typically end up
using 10-12 gallons of 15% on my OS1.40's. Which means buying a couple of
$700 battery packs totally out of the question. Hopefully this emerging
technology won't drive away even more of the guys like me who are
lucky to get out once a week during the summer. </FONT></DIV>

<DIV><FONT face=Arial size=2>Guys,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I'll jump back in here; Jim, your perceptions
are correct. My decision to go to Electric was based on some fairly
bad luck with engines last year--It was time to up-date power-plants as I
was driving my old stuff to pieces trying to get all the power I
could out of them. I purchased what I thought was going to be the
hot ticket engine and had a series of unfortunate events with it. By
the end of the season, I hadn't done a lot of flying--but had had a load
of problems. It was time to re-evaluate what I was doing. My
business doesn't allow for scads of practice time, so when I get the
chance--I like for it to count. Since I try to do things as right as I
can, I generally end up with three sets of everything eventually--you
know; the Primary, the Back-up, and the One you're building--never
seems to quite work out that way--but at least it's the plan.
I was flying Temptations, but had crashed one and hurried to get the
second done and while pretty good airplanes, I was beginning to think
there might be a change to a wider body style in my
future. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So basically I was looking at a clean
slate. AND I had 15 years of accumulated stuff to sell since
the last time I sold off my stuff to start over. I heard
and read about some of the guys having success with electric and was
intrigued, fooled around with the smaller park and indoor stuff and got to
know a little about it--decided with proper care, all parts of the systems
are pretty reliable and reasonably safe. I talked to a couple of the
old hands and a couple of fairly young guys and they were all enthusiastic
about the larger stuff and so I thought--"Hey, I've got to get to know
some new power-plants anyway--why not get up to speed with
electric?! " I got hooked-up with FMA through the small stuff
because they treated me fairly on some of the issues I was having and were
designing some battery protection features, cell balancing chargers and
some new batteries for the larger stuff.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Initially, I thought about--actually, I had
made up my mind--to do a Plettenberg outrunner so I wouldn't be dealing
with gear-sets. Eventually, It became clear that between what was
available a few months ago and the Hacker--that the Hacker set-up was
going to give better performance. One person likened the Plettenberg
to a good 110 system and the Hacker to a good 160 system. That may
have changed by now--but you still have to look at weight vs.
performance. I ordered an Impact--but had the brand new IC powered,
reasonably light Temptation that wasn't selling and decided to convert
it. That turned out to be fairly easy. First I started with a
conversion mm kit from Esprit out of Florida--but we saved 5 oz. by going
to a solid CF nose plate and end grain reinforced balsa in the rear opened
up and then the whole front of the airplane is open for
cooling. The batteries mounted exactly where the tank was--I beefed
the mounting up a bit. I put on a set of Matt's gear.
I'm making weight by all of .5 oz. I may be a smidge tail heavy and
may run the rec. batt to the front.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Flying. I'm fooling with the throttle
curve a little--experimenting with the feel. I'm guilty of probably
not experimenting enough sometimes when something already works pretty
well. It's probably not a whole lot different than the difference
between two and four cycle--but my experience is limited there
also.</FONT></DIV>
<DIV><FONT face=Arial size=2>There may be some interaction between what
the FMA discharge protection modules(DPMs) and the controller is doing in
regard to throttle response and how the motor surges to signal you're
running low on electrons--but so far, everything is working
reliably. We also know we're driving the hell out of the 3200s--but
I can't stand any more weight--so I'm sorta stuck for now. They've
got some experimental 4000 10s2ps that Orland is going to try--but they
weigh a few oz. more--but he's got lighter airplanes and can stand
it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I mentioned time--45 CONSECUTIVE flights with
a complete pattern in each. 12 or so trips to the field and
power-plant related problems have not ruined a flight. I haven't had
to 'tune' for the first couple in a session--first is identical to the
last. I'm working on throttle management--it's different. I'm
looking at this as a transitional year--to learn, to see what works best
for me, to figure out the logistics of charging at home and the field--or
on the way, to make it safe--all that good stuff. So far I'm
satisfied with the results.</FONT></DIV>

size=2>Having flown Tony's Partner only once (but watched it fly quite a
bit), and having seen just a few other electric pattern planes (Jason's,
and Billy Meadows'), the flying advantage of the electric was enough to
make me want to get one going, regardless of the learning curve.
From my perception, the pilot does feel the difference between the
glow and electric setups regarding less vibration. The plane is
going to be easier to setup for a constant speed envelope, where there
is less of a "gap" between slow and full-throttle horizontal velocity.
With the narrowed speed envelope, it MUST be a tad easier to setup
the plane as the "one" setup has a smaller velocity range to work and be
consistent in.</FONT> <BR><BR><FONT face=sans-serif size=2>I'm just
trying to stir up another side of the discussion. I hope that some
of the folks who have more of the "flying" experience with the electric
2M setup will relay their experience, and describe to us the piloting
differences, trim differences, etc.</FONT> <BR><BR><FONT face=sans-serif
