RE: (ET) A funny thing happened on my way to a new relay

["Markus Lorch" <mlorch vt edu>]

Great, thats just what I have in mind for my E20 as well. I've already 
ordered a suitable Rheostat a couple of days ago and was thinking
of adding a small 12V battery to (experimentially) increase the 
field voltage when lightly hitting the breaks ... thus having better 
motor-breaking

I did two things to speed up reverse.  First a momentary button to bypass
the resistor.  Second a reostat with self keeping relay.  You can field
weaken, but when you stop or change direction the relay drops out.  This
prevents high current start ups if the field weakening is left on.  I do
this with a e-20 motor.
