<DIV> Very good of HL I'm happy for you. Could you give us more info on
what motor and speed control so others could benefit from your experience, and
please keep us updated on your progress.</DIV>

<DIV><FONT face=Arial>Just to update the thread, I heard today from Hobby
Lobby and they recommend a different motor/esc combo that will run with my
5s4p packs in series...so I'll go with that. They also said they would
give me a 50% credit for the ESC which I think is pretty nice considering
that I take full responsibility for burning it up<G>.
</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Is there any way to tell that I fried the motor or
not? H_L says that I can send it back to Actro for repair, but I hate
to send it back to the continent if it isn't broken.</FONT></DIV>

George and Gang,</FONT></SPAN></DIV>
<DIV><SPAN class=296374515-11012006><FONT face=Arial color=#0000ff>Lacking
a copy of one of the fancy e-simulator tools, you can go to <A
href="http://www.aveox.com">www.aveox.com</A>, and find their free
simulator. It ain't fancy, but if you adjust the number of NiCad
cells used by default to get 34 or 35V, then it produces meaningful
results. Plug in the numbers for Kv, winding resistance, and no-load
current of your motor (should all be available on the mfgr's website
and to any who don't shame on you!) and you will get a good +/- 10%
estimate of the current you should expect with a given prop. The tool
works, and can save you money and grief. Most importantly, use a current
meter the very first time you try any new prop size! Sears sells a nifty
clamp-on DC current meter for $50. RVP, what was the part number on that
critter, again?</FONT></SPAN></DIV>

<DIV><FONT face=Arial>Thanks, Steve- I picked the Actro 32-3 because I'm
going to use one in my Ion and I therefore knew that it would run on the
5s4p packs. I picked the prop at the upper end of the Hobby Lobby
range...didn't do the RPM/volt calculation...but if that is true, even
with only only one pack(5S), I'd be pushing 10K rev's ..... My
Plettenberg turns about 9K with 42 Volts. As to the cell count---
at 1.5 volt per cell, 26 nicad cells is about 39 volts...and since I
knew the actro was run in heli's with the 10S setup, I thought that was
pretty close.....</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I'm not trying to be contentious, I'm just trying
to learn how to do these calculations properly in the future. Its
all well and good to say use a proven system, but someone has to "prove"
each one as they come available. I guess I need much more
info before I become a pioneer<G>.</FONT></DIV>

<DIV> I'm trying to learn some of this also, so take anything I
might say with a grain of salt, I will be using a standard setup this
spring that many have already used.</DIV>
<DIV> From Hobby-Lobby site for Actro 32-3</DIV>
<DIV>
<DIV align=left><FONT face="Verdana, Arial, Helvetica, sans-serif"
color=#ff0000>For 14-26 cells in propeller models and 28-32 cells in
helicopters. Propeller range is 13" to 18" in diameter. This 3 turn
motor has an RPM/Volt of 555, resistance of 34 mOhm. Maximum
efficiency of about 89% in the 50-95 amp draw range. Power output in
the 550-2000 watt range.</FONT></DIV></DIV>
<DIV> Sounds like you used 5S4P in series 42 volts X <FONT

rpm.</FONT></FONT></DIV>
<DIV><FONT face=Verdana color=#ff0000><FONT color=#000000> I
tried to run a setup on motor calc but there data is so outa date
nothing there to use maybe somehas elecalc to do figures for
you.</FONT></FONT></DIV>
<DIV><FONT face=Verdana> The other thing I have found on Hobby
Lobby site is most of the time they talk about cells is to NiMh or
NiCd if Lipo's they generally say so.</FONT></DIV>
<DIV><FONT face=Verdana> </FONT> Hope this will generate
some info and the best of luck.</DIV>

Electric Power Consumption</DIV>
<DIV><BR></DIV>
<DIV><FONT face=Arial>I have a problem with an electric conversion
which while not precisely pattern related, I'm sure will be
applicable to electric pattern problems...so I'll ask it
here.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I am trying to convert a Showtime from YS 110
4 cycle power to electric power. After looking around the web,
I got an Actro 32-3 - which is a popular motor for the Ion electric
helicopter. I know that this motor runs well with available
ESC's on 5S4P lithium packs, so I set it up with a 17X12 APC e prop
and a 77amp ESC from Hobby Lobby ( esc and prop recommended on
their website). To make a long story short, the
ESC litterally burned up 30 seconds into the first flight....but BOY
WHAT POWER for that 30 seconds<G>!!!</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>OK, so I'm thinking that burning up probably
indicates a problem.....and I start to investigate...I hook up a
watts-up to my Focus II with a Plettenberg 30-10 and a 21X12
APC and it pulls about 65 amps at full throttle on the bench....Then
I set up the Showtime and it tops 75 amps at half throttle!! HMMM,
so there is the problem....Now I try to make changes to decrease the
amperage -- larger prop and smaller prop---no major change, then I
tried just using a 5 cell pack cutting voltage in half...still about
the same....so the question is: How do you adjust the current
drawn by an electric motor? Can this set up be
salvaged...Where did I go wrong and how can I avoid this in the
future? </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>TIA for your help and the benefit of your
experience!</FONT></DIV>
