Hi Andrew,
I initially shared your views on soldered pins having fewer problems than
crimped pins. That is until I used “machined” pins for crimping. Using
machined pins provided a level of reliability much better than my crimped pins
using the “tin foil” pins. Turns out even better than solder as it did not
have a sharp stress point as a solder join may have. The machine pins have
a solid body with a cavity in one in for the wire, a crimp puts 3-4 indentions
into the barrel of the pin and secures the wire. You can really pull on
the wire and I have never had one come out.
Naturally, If it is done correctly then just about any method
will work, but my personal opinion is that using machined pins and crimping is
the best method I have found.
There is one downside to using machined pins – they are pricy. But,
then what price for a reliable connection – right? I only used them for
what I considered flight critical connections due to cost and never had one
fail.
Not suggesting you change anything, just wanted to give you my benefit of
going down the same path.

Thanks
Charlie. Yes all my earths go back to a forrest of tabs. Pretty sure it will be
an earth issue also, as its a new problem on a system that has been working
well. Some connections are crimped as in the later part of wiring I got a bit
tired of sniffing solder. Nearly all my wiring problems are associated with
those crimped connections so I just solder them now as they appear.
There is an aerial ag business based on our farm, I watch & admire them
flying close to the edge of the air all the time. But its not for me, I really
do prefer to fly in the middle, so I just wanted make sure the plane would cool
enough to get me there next time. But yeah, I'll take the wheels off &
check to see if I've spun a bearing.
Andrew
