<DIV>Ron, you are right that the Dean's connectors are less prone to loosing
contact due to wear because of the way the contacts work. The tips of the
plug may wear due to spark, but the mating surfaces do not. I have
hundreds of flights using my Deans arming plug with no issues. Tips show
errosion due to sparks but the mating surfaces show none of the erossion.</DIV>

<DIV>The is supposedly a way to allow the capacitors of the ESC to charge slowly
by using a resistor in the circuit to pass current more slowly to charge the
capacitors. I have not done this but if you do a search in RCU or RCG, you
will probably find the info. I have also heard there is a recommendation
to not do this because the ESC may power up with less than minimum required
voltage and the logic may not work correctly. Like I said, I have not done
this, just passing on what I have heard.</DIV>

style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>I have a
problem which I am sure many other E-powered airplane owners <BR>have
that I'd like to solve. I use an arming plug to connect the two
<BR>5S Lipo packs to the ESC. On initial contact of the arming plug
with <BR>the receptacle, there's a big spark thrown. Eventually
the contacts <BR>on the arming plug and receptacle get burned to the
point where the <BR>electrical contact is very bad. Yesterday I
had to land my airplane <BR>deadstick because (I think) the ESC saw what
it thought was low <BR>voltage out of the battery that was actually due
to the burned arming <BR>plug/receptacle contacts. BTW, I am using
high-amp Anderson Power <BR>Pole connectors, which are probably more
susceptible to having the <BR>contacts burned than would Deans Ultra
connectors.<BR><BR> I have thought about putting a BIG capacitor in
parallel with the <BR>arming plug, that would damp the initial current
surge which causes <BR>the spark. The capacitor could be removed
before flight. However, <BR>I'm wondering if there's a more
elegant solution.<BR><BR>Ron Van
