<DIV><FONT face=Arial size=2>The Eclipse looks like it might be an ideal
airplane to build as an electric. I was wondering how well it flies
compared to the other top pattern planes of the day? As good as the
stuff coming from Europe? Starting to think about my next project.
Any suggestions would be appreciated.</FONT></DIV>

<DIV><FONT face=Arial size=2>I have converted one of my Eclipses to

<DIV><SPAN class=msg><FONT size=2>I have been able to get another five
flights on the electric Eclipse. This time I had the Hacker C50 14XL 6.7:1
motor and the APC E22-12 prop. I am impressed on how well it flies even in a
moderate wind (some 15 mph). It has plenty of vertical for the Masters
pattern. <BR><BR>I did experience a battery failure. The air temperature was
93F. The maximum motor temperature I measured was 132F after landing. The
batteries never got hot. The first picture shows that cells second from the
end failed. I discussed the situation with Thunder power. They are replacing
the TP6000 5s3p packs under warranty. They have had some failures in these
packs. Mostly with the packs installed in pattern planes. Apparently the
cells are not getting enough cooling. I have since revised
support plates with plenty of cooling holes. I have also ducted all of my
air across the motor and directly to the batteries. I hope to get some more
test flights next weekend. I still hope to bring the plane to the Nats. Just
need some more practice. <BR><BR>The original conversion weighed in at
11#-6oz. That means I gained exactly one pound, one ounce in the conversion.
I now have the plane below 11# by 1 to 2 oz. Here is what I had to do:
<BR><BR>First I removed the wheel pants and Dave Brown 3" light tires. I
also carved all excess material from the Bolly CF landing gear. I will be
using the central hobbies aluminum axels and MK 55mm tires. This saved some
5oz. <BR><BR>Second I removed the 1600ma NiMH receiver battery and installed
a 770ma NiMH battery. This saved 2.1 oz. <BR><BR>Third I removed all excess
material from the fuselage. You don't need wide flanges on an </FONT><A

almost no vibration in the air frame. <BR><BR>There is some two more ounces
of weight savings I could do such as using the new JR770 pcm-s credit card
mini receiver and using the mid size aileron servos. This is more expensive
and is not necessary. <BR><BR>All in all, a glow conversion to electric can
come in under 11#. It is best to start with a plane weighing in at no
more than 10#-4oz. </FONT></SPAN></DIV>
