John:
I was just going to make that reference to R/C airplanes.
I fly large electric planes, my largest being almost 12 pounds. I run
10 lithium polymer batteries in series for a total of just over 34 volts
at full load which draws approximately 62 amps. I'm using 45 amp APP's
and they work just great. I put the plane through some very high G
maneuvers and have never had a problem with the APP's coming apart.
However I do use a separate battery for my receiver so if I lose power
to my motor I still have control of the plane.
I think the issue is proper installation. Since I use lots of APP's I
went ahead and purchased the ratchet crimping tool from West Mountain.
However, if I just had one set of APP's to deal with, ie a K2 I don't
think I would want to purchase the crimper and would probably solder
them. But I think the trick here would be to watch the amount of heat
applied to the connector.

Our ARES group has standardized on the Anderson PPs and they
have been installed on all equipment used by our members.
I can't for the life of me understand the hatred some show of APPs.
Like any other connector, if installed PROPERLY and used for the
intended purpose, they do a great job. ANY connector can fail if
installed in a ham-handed manner, even the most expensive. My local
ARES group has standardized on these, and not just because "the ARRL
said so", as some imply. They truly are a superior connector if
installed to manufacturers spec. Crimp or solder, your choice,
although if crimping is good enough for NASA, Boeing,
McDonnell-Douglas et al, it's good enough for me.
Also, the roll pins are NOT recommended by most sellers of APPs, nor
Anderson. They do not stay put, and can cause a disaster if they fall
into the wrong place(see Murphy's Law). Better to use a drop of Super
Glue or similar after the connectors are dovetailed together. The
clip made to hold sets together is a great idea, although it does add
to the expense.
BTW, RC modelers use APPs extensively with no trouble or unwanted
disconnects, and this is certainly a harsher environment than most of
us will use them in.
Just my 2 cents, now back in my hole!!
