Probably because some readers never consider the concept that some of
the articles on the web site have been posted for well over a decade and
may contain out-of-date information or may be intended for people who
want to spend as little as possible to operate a vehicle. For example,
the MAG relay controller with diode mixer (invented 13+ years ago) still
holds the record for the least expensive on-off tank-style mixing
controller that anyone with basic wiring skills can build. I can assure
you that more than a few of us "old guard" are sufficiently tech savvy
and still design/make/use some truly state-of-the-art components.
BTW: New and/or more features doesn't necessarily mean "better".
Reliability and "effectiveness" are the keys to success. The solid
state relays that you denounce controlled both the Tiger and Hetzer in
100+ combined battles over a 10+ year period. While the early versions
of Sabertooth and other more expensive ESCs were blowing up on a regular
basis, those "arcane" solid state relays and a simple 16-bit PIC
controller were still going.
More importantly, at the time they were first introduced by Dr. Sommer,
the overall system solution was roughly 50% of the equivalent
commercially available system, thereby allowing more people to use
proportional control without spending too much. Now (after 10+ years),
commercially available systems (like the Talon) have finally come down
to that price point, while providing the same level of reliability.

Ive also never understood why the old guard on this mailing list insist
on using the most arcane or feature-deprived methods and technology they
can find; case-in-point the MAGs and the people who use solid state relays.
